Recent catastrophic earthquake events have reinforced the necessity of evaluating the seismic performance of buildings. Notably, the buildings can go into the plastic phase during a striking earthquake disaster. Under this condition, the current design codes assume seismic response reduction by virtue of the energy dissipation capacity of the structural members. In the strong-column–weak-beam design, which involves I-shaped beams and boxed columns, the mechanism is defined as a standard design scheme to prevent the building from collapsing. Therefore, energy dissipation relies highly on the I-shaped beam performance. However, the I-shaped beam performance can differ depending on the loading history experienced, whereas this effect is untouched in the prevailing evaluation equation. Hence, this study first performs cyclic loading tests of 11 specimens using different loading protocols. The experimental results clarify the fluctuation in the structural performance of I-shaped beams depending on the applied loading hysteresis, proving the necessity of considering the stress history for proper assessment. Furthermore, the database of experimental results is constructed based on the previous experimental studies. Ultimately, the novel evaluation equation is proposed to reflect the influences of the loading protocol. This equation is demonstrated to effectively assess the member performance retrieved from the experiment of 65 specimens, comprising 11 specimens from this investigation and 54 specimens from the database. The width–thickness ratio, shear span-to-depth ratio, and loading protocols are utilized as the evaluation parameters. Moreover, the prediction equation of the Bauschinger effect coefficient is newly established to convert the energy dissipation capacity under monotonically applied force into hysteretic energy dissipation under the cyclic forces.

Non-structural members, such as roofs and ceilings, become affixed to main beams that are known as structural members. When such main beams experience bending or compressive forces that lead to lateral buckling, non-structural members may act to restrain the resulting lateral buckling deformation. Nevertheless, neither Japanese nor European guidelines advocate for the utilization of non-structural members as lateral buckling stiffeners for beams. Additionally, local buckling ensues near the bolt apertures in the beam–roof folded plate connection due to the torsional deformation induced by the lateral buckling of the H beam, thereby reducing the rotational stiffness of the roof folded plate to a percentage of its ideal stiffness. This paper conducts torsional experiments on roof folded plates, and with various connection methods between these plates and the beams, to comprehend the deformation mechanism of roof folded plates and the relationship between their rotational stiffness and the torsional moment. Then, the relationship between the demand values against restraining the lateral buckling of the main beam and the experimentally determined bearing capacity of the roof folded plate is elucidated. Results indicate the efficacy of utilizing the roof folded plate as a continuous brace. The lateral buckling design capacity of H beams that are continuously stiffened by roof folded plates is elucidated via application of a connection method that ensures joint stiffness between the roof folded plate and the beam while using Japanese and European design codes.

With demand for the long-term continued use of existing building facilities, structural health monitoring and damage detection are attracting interest from society. Sensors of various types have been practically applied in the industry to satisfy this need. Among the sensors, piezoelectric sensors are an extremely promising technology by virtue of their cost advantages and durability. Although they have been used in aerospace and civil engineering, their application for building engineering remains limited. Remarkably, recent catastrophic seismic events have further reinforced the necessity of rapid damage detection and quick judgment about the safe use of facilities. Faced with these circumstances, this study was conducted to assess the applicability of piezoelectric sensors to detect damage to building components stemming from concrete cracks and local buckling. Specifically, this study emphasizes structural damage caused by earthquakes. After first applying them to cyclic loading tests to composite beam component specimens and steel frame subassemblies with a folded roof plate, the prospective damage positions were also found using finite element analysis. Crack propagation and buckling locations were predicted adequately. The piezoelectric sensors provided output when the concrete slab showed tensile cracks or when the folded roof plate experienced local buckling. Furthermore, damage expansion and progression were detected multiple times during loading tests. Results showed that the piezoelectric sensors can detect the structural damage of building components, demonstrating their potential for use in inexpensive and stable monitoring systems.

In Japanese Recommendation for Design of Building Foundation, the method to estimate steel pile's ultimate strength in the liquefied soil at pile's collapsing due to the significant earthquake is proposed. However, there are some cases, in which steel piles do not fail and continue to carry the dead load, even though they become plastic due to the previous seismic motion. The ultimate strength of steel piles, which have already accumulated the damage due to the multiple earthquakes, may decrease and the piles may collapse when they experience the subsequent massive earthquake. In this paper, centrifugal tests for the case where piles are subjected to multiple earthquakes are conducted to clarify pile's collapse mechanism in the liquefied soil and pile's ultimate strength. Furthermore, the estimation method of pile's cumulative damage is presented based on results of centrifugal tests and numerical analyses.Fig. 1 shows the model and instruments. The specimen consisted of a superstructure and a footing beam with mass, two bending plates, four piles, and a saturated sand layer. Table 2 shows specimen parameters, which are pile's diameter, the relative density of the soil and the height-to-width aspect ratio of the superstructure. The centrifugal tests were performed under the centrifugal acceleration of 40 g.Figs. 11(b), (c)-16(b), (c) show response time histories of Case 4. The bending strain at the pile head for the first shaking reached ε_lc after the soil liquefied and superstructure's inertial force became maximum. The piles became inelastic although they kept their ability to carry the dead load even after shaking. The maximum value of superstructure's acceleration and pile's varying axial force during the second shaking were almost the same as that of first shaking. On the other hand, the bending strain gradually increased and reached the maximum value, ε_b,max, at 35 s. As shown in Fig. 19, the bending strain exceeded ε_yc for Case 2, but did not reach it in Case 1, Case 3, and Case 4. For all specimens, the local buckling occurred at the pile head, as well as at the bottom and the center of the pile as presented in Photo 1.Fig. 20 shows the relationship between pile's strength on centrifugal tests and the M-N interaction curves of design criteria. For Case 2, Case 5-Case 8, which collapsed during the first shaking, results at ε_b,max exceeded the M-N interaction curve of Japanese Recommendation for Design of Building Foundation and were distributed roughly following the ultimate strength curve. However, for Case 1, Case 3-Case 4, which collapsed subjected to multiple shaking events, the values at ε_b,max did not reach the ultimate strength curve and were smaller than those of Case 2, Case 5-Case 8.Fig. 21 represents the calculation flow of pile's accumulated plastic strain amplitude, ∑ε_pa, which is defined as pile's cumulative damage indicator in this paper. Mechanical characteristics' relationships (as shown in Figs. 26(a)-(c)), as well as regression equations (Eqs. (15)-(18)) are obtained based on analysis results of Figs. 22-25. Eq. (19), which is derived from Eqs. (15)-(18), shows the relationship between normalized ∑ε_pa and plastic deformation capacity μ_cmax. Fig. 27 describes the comparison between the values of centrifugal tests, numerical analyses, and Eq. (19). It is concluded that the cumulative damage of the steel pile, which collapses subjected to multiple earthquakes, can be evaluated using Eq. (19).

 Steel piles below high-rise buildings may carry larger varying axial force generated by the overturning moment than those below low- or medium-rise buildings. On top of that, the subgrade lateral stiffness reduces drastically due to the soil liquefaction during a significant earthquake. Steel pile's horizontal strength may decrease due to the lower position of the inflection point. In this paper, centrifugal tests of the superstructure with high height-to-width aspect ratio, steel piles, and the liquefied soil system are presented. The collapse mechanism and the horizontal load bearing capacity of steel piles in the liquefied soil are clarified. Fig. 1 shows the model and instruments. The specimen consists of a superstructure with mass, a footing beam with mass, two bending plates, four piles, and a saturated sand layer. Table 2 shows specimen parameters, which are the height-to-width aspect ratio of the superstructure and the relative density of the soil. The centrifugal tests were performed under the centrifugal acceleration of 40 g. Figs. 5-18 show response time histories of Case 1-Case 6. The bending strain at the pile head gradually increases toward the one side after the soil liquefaction and reaches the maximum value, ε_b,max. After reaching ε_b,max, the piles of all specimens collapse, except for Case 4. As presented in Fig. 20, in the case of the same D_r values, the sum of pile head's shear forces, ΣQ_ph at ε_b,max are approximately equal regardless of the height-to-width aspect ratio. An additional shear force generated by pile's P-Δ effect, Q_PΔ,pl, accounts for the largest part in ΣQ_ph. On the other hand, in the case of high height-to-width aspect ratio, the value of Q_PΔ,pl is smaller issued from larger additional shear force generated by the superstructure's P-Δ effect, Q_PΔ,s. Fig. 21 shows the relationship between pile's strength on the centrifugal tests and the M-N interaction curves of design criteria. Ratios of pile's varying axial force to pile's flexural buckling strength, N_pl/N_cr0, are the same until at ε_b,max regardless of the height-to-width aspect ratio. For piles subjected to the dead load and the varying axial compression force of all specimens, the combinations of axial force and bending moment at ε_b,max are distributed roughly following the ultimate strength curve as presented in Ref. 6. On the other hand, the results of the pile subjected to the dead load and the varying axial tensile force in the case of D_r=30% are lower bound to the M-N interaction curve as shown in Ref. 9 and those of the case of D_r=60% approximately reach that curve. As presented in Figs. 22-24 and table 3, steel piles' collapse mechanism is concluded as follows. Pile's bending moment reaches pile's full plastic moment, _vrM_pc,cr0, at the top and the bottom of the pile subjected to the varying axial compression force. In the case of D_r=60%, pile's bending moment also approximately reaches _vrM_pc,cr0 at those points of the pile subjected to the varying axial tensile force due to the increase of the distribution ratio of superstructure's and footing beam's shear force after at ε_yc. As shown in Fig. 24, it is concluded that steel piles' horizontal load bearing capacity can be evaluated easily using steel piles' horizontal strength based on the location of the inflection point in the liquefied soil and pile's plastic bending strength reduced by initial axial force.

 In the current Japanese design code of pile foundations, the buckling behavior of pile member is not taken into account. This is because the surrounding ground restrains buckling of the pile member. However, when the ground liquefies, the stiffening force for horizontal deformation of the pile weakens. Therefore, when slender pile is subjected to high axial compression forces as a result of increased vertical loads by overturning moment of superstructure under the strong earthquake, flexural buckling may occur in pile member in soft ground. The buckling behavior of steel pile in liquefied ground has been studied previously. This study investigated the dynamic buckling behavior of reinforced concrete (RC) pile using a centrifuge model. This paper investigated the dynamic buckling behavior of reinforced concrete (RC) pile using a centrifuge model. Three specimens with soil densities and input waves as variables were tested by uni-axial shaking. Buckling failure occurred in the pile members of all centrifugal models after the ground were liquefied. All pile members formed three plastic hinges at the pile head, lower side, and middle position. The measured buckling strength of the centrifuge RC pile model was evaluated by extending the tangent modulus theory. In the shaking table test under a 40 G field, the specimen used RC pile models, saturated soil (Toyoura sand) with a relative density of 30%, footing and a superstructure model with a natural period of 0.027 sec (prototype scale: 1.10 sec). Shakings were two Sweep wave (maximum acceleration: 4.19 m/s², 4.44 m/s²) and one Rinkai wave (maximum acceleration: 7.36 m/s²). The lateral displacement of the pile foundation was fully restrained so that the only the vertical load (the sum of the sustained load of the superstructure and the temporary load by overturning moment) acted on the piles. Buckling failure occurred in the pile members of the centrifugal model after the ground was liquefied. After the pile buckled, the footing sank, and the seismic response of the superstructure decreased. The measured buckling strength of the centrifuge RC pile model was evaluated by extending the tangent modulus theory (Engesser and Schanley). Since concrete (mortar) is a non-linear material, the tangential stiffness changes according to the acting axial force. Also, even if the ground liquefies, the stiffening force for horizontal deformation of the pile members does not become zero. Therefore, in order to evaluate the buckling strength of RC pile members in liquefied ground, it is necessary to consider the influence of the non-linearity of concrete and the decrease in the stiffening force of the surrounding ground.

<jats:title>Abstract</jats:title><jats:p>During earthquakes, I‐shaped beams installed in a braced structure are subjected to a bending moment and compressive and tensile axial forces transmitted from the braces. The buckling behavior of a beam under the impact of an earthquake is thereby more complex than that under no axial force or constant compressive axial forces considered in previous studies. In this paper, cyclic loading tests and numerical analyses are presented with emphasis on cyclic buckling behavior and moment and deformation capacity of the beams subjected to synchronized flexural and axial loading. As a result, it is confirmed that the I‐shaped beams originate local buckling under compressive axial force, whereas the strength is regained up to the full plastic bending moment under tensile force. Based on the results obtained, this paper presents evaluation formulae for estimating the ultimate strength, plastic deformation capacity, and cumulative plastic deformation capacity. Finally, an empirical formula to convert cumulative plastic deformation capacity into hysteretic energy dissipation is proposed.</jats:p>

 When steel moment frames are subjected to seismic forces, H-shaped beams carry the gradient flexural moment. Large cross-section beams are used as main beams to design structural members effectively in real large space structures. Long span beams may not possess the plastic strength due to lateral buckling, so that many lateral braces along the beams should be set up to prevent the lateral bucking deformation (AIJ 1998). Most oy beams in frames are connected by continuous braces such as folded-roof plates, which are effective to prevent the lateral buckling oy beams. However, in the Japanese design code, non-structural members are not considered as the braces.  On the other hands, there have been many moment resisting frames with dampers to prevent damages oy main frames recently, and then H-shaped beams connected with dampers are subjected to compressive axial forces in addition to gradient flexural moment. If the beam carries the large axial force induced by the damper during earthquake, the lateral-torsional buckling behavior oy H-shaped beam becomes more unstable than that under flexural moment only. The axial force which the beams carry is possible to exceed 30% oy yield load oy the beam.  Therefore, in this paper, the lateral buckling behavior for H-shaped beams with continuous braces under gradient flexural moment and compressive axial force is clarified and elasto-plastic lateral buckling stress oy the beams or lateral stiffing force and rotational stiffing moment oy continuous braces are evaluated by the energy method and numerical analyses.  In this study, for H-shaped beams with continuous braces subjected to gradient flexural moment and compressive axial force, two types oy loading conditions and two types oy bracing rigidities are considered. One oy the loading conditions, which is called as Type A, is the case that the upper flange's compressive load is larger than the lower flange's one in the left side oy beam as shown in Fig. 3(a), and another, which is called as Type B, is that the upper flange's compressive load is smaller than the lower flange's one in the left side oy beam as shown in Fig. 3(b). Furthermore, the ratio oy the compressive axial force, P₂ to P₁ is represented as an axial force ratio ‘p’ in equation oy elastic lateral buckling load. The continuous braces are divided into the lateral braces, k_u, and rotational braces, k_β, as shown in Fig. 1. In the case oy TypeA, k_u is effective for preventing lateral deformation oy compressive upper flange, whereas in the case oy TypeB, k_β, is effective for preventing torsional deformation.  This study is conducted by the following procedures:  1. The equations oy lateral buckling loads oy H-shaped beams with continuous braces under gradient flexural moment and compressive axial force are derived by energy method. To simplify the equations by energy method, the new equations oy lateral buckling loads are suggested with reference to the terms oy the flexural and torsional rigidities oy beams, the rigidities oy braces, and condition oy the loads.  2. The elasto-plastic buckling behaviors oy the beams are simulated by elasto-plastic large deformation analysis. The lower bound oy the elasto-plastic buckling stress oy the beams can be evaluated with the interpolated buckling curve between those oy bending member and compression member, which are provided by Recommendation for Limit State Design oy Steel Structure (AIJ), depending on the axial force ratio.  3. The upper bound oy moment and lateral force which continuous braces carry at the lateral buckling oy beams is evaluated based on the ratio oy the flexural and torsional rigidities oy beams, the rigidities oy braces, the axial force ratio, and the gradient oy flexural moment.

 In our previous paper, centrifuge tests of superstructure-pile-liquefied soil systems have been conducted, and dynamic ultimate mechanism of steel piles subjected to the vertical force and horizontal force in the liquefied soil was clarified. It is shown that piles' ultimate strength was estimated using the M-N interaction curves. In the other hand, for real structures, reinforced concrete is filled at a pile head to fix a connection between steel piles and a reinforced concrete footing beam. It is considered that the flexural buckling length of steel piles becomes shortened because pile head filled with concrete acts as the rigid body. In this paper, centrifuge tests of superstructure-pile-liquefied soil systems are conducted to compare the dynamic ultimate mechanism of steel piles reinforced at pile heads with that of non-stiffened ones. Subsequently, piles' ultimate strength is estimated using M-N interaction curves with pile's equivalent buckling slenderness ratio.  Figure 1 shows a specimen of centrifuge tests. The specimen is configured by a superstructure represented consisting of a mass and a pair of spring elements, four piles and a saturated sand layer. In this paper, an aluminum cross section member is inserted into the pile head of a specimen to reproduce a real pile reinforced filled with concrete at the pile head. In Case 1, the pile cap is laterally fixed, and then only varying axial force acts on the piles. In Case 2, the pile cap can laterally move, and the vertical and horizontal forces act on the piles. The centrifuge tests were performed under centrifugal acceleration 40 g.  Figures 7 and 8 show the response time histories of Case 1 specimens and table 5 shows the pile's maximum axial force. It is shown that the bucking strength becomes larger as reinforcement length at the pile head is longer.  Figures 14 and 15 show the response time histories of Case 2 specimens. For all Case 2 specimens, the bending strain increased immediately after soil liquefied.  For specimens of Case 1, the dynamic buckling strength of piles is evaluated. Figure 13 shows the relationship between observed pile's dynamic buckling strength subjected to only vertical load and buckling curves for Japanese limit state design of steel structures and Japanese design standard for steel structures. Here, the equivalent slenderness ratio is calculated by the ratio of pile's elastic flexural buckling load to the yield load. For a pile reinforced at the pile head, elastic flexural buckling load developed by the energy method in Section 3.3 is applied. The buckling curve of Japanese recommendations for limit state design of steel structures is lower bound of flexural buckling strength of piles in the liquefied soil. As the results, it is shown that the buckling stress curve with the equivalent slenderness ratio can be applied to estimate flexural buckling stress of pile reinforced at the pile head.  Next, for piles subjected to lateral and vertical forces, ultimate strength is evaluated using Japanese current design criteria. Figure 19 shows the relationship between ultimate strength of piles on centrifuge tests and the M-N interaction curves for the design criteria. The axial force of piles is divided by elastic-plastic buckling stress of piles obtained from buckling curve of Japanese recommendations for limit state design of steel structures as shown in Fig. 13, and the bending moment at the maximum bending strain position is divided by the full plastic moment of piles. It is shown that the M-N interaction curves of Japanese recommendations for design of building foundation is lower bound of pile's ultimate strength in the liquefied soil at the maximum bending strain.

This paper presents the damage mechanism of gymnasium building with RC frame and steel roof structure damaged by the 2011 Off the Pacific Coast of Tohoku Earthquake. The result of pushover analysis reveals that the damage at top of column progresses from the frame with seismic walls to the moment resisting frame. Furthermore, the damages at top of column around the frame with seismic walls are confirmed by seismic response analysis. Additionally, the cause of the difference between push over analysis and seismic response analysis is investigated in terms of the distribution of external forces and shear forces at the top of column.

Our previous papers proposed a pin column support system on 1^st story, which consist of the reinforced concrete downside column and the steel topside column to keep column elastic against base shear force issued by the huge seismic force. The joint consists of an anchor bolt, a cover plate on the RC column and a shear plates into RC column. In this paper, the vertical loading tests are performed to clarify the transmission system of axial force for the joints between the reinforced concrete downside column and the steel topside column. Finally, the yielding strength and ultimate strength are estimated by the closed form solution of the experimental results.

The steel piles beneath the building structures may buckle when the soil becomes liquefied during the large earthquake. In our previous papers, the static buckling behavior of the steel pile is clarified, but the shaking tests of the frames with circular tube piles and the soil, has not been performed to clarify the dynamic buckling behavior. In this paper, the centrifuge test which is a kind of the shaking tests, is applied for the dynamic behavior of small scaled models with the similarity rule, and it is shown that the collapse mechanism issued from dynamic flexural buckling for the piles in liquefied soil is described, and the piles' strength with liquefied soil is larger than that without soil because of the subgrade reaction.

Our previous papers have evaluated the effect of the eccentric braces to restrain the buckling deformation for H-shaped compression members with an eccentric brace at the center of the member, and with continuously eccentric braces, respectively. But the effect for the continuously eccentric braces may be different from that for an eccentric brace at the center of the compression member. In addition, the reduction ratio of the buckling stress with web deformationin inelastic range may be different from that in elastic range．If it makes the effect of each eccentric bracing equivalent, it is more practical to design the compression members with eccentric braces in the space structures. This paper compares the elasto-plastic buckling behavior for H-shaped compression members with eccentric braces at the center of members to that with continuously eccentric braces, and estimates the equivalent of the bucking bracing stiffness for two kinds of eccentric bracing methods within critical slenderness ratio.

There are some differences in the steel structures from the view of seismic design and practice between U.S., and Japan. In Japan all columns and beams are the seismic elements in X and Y directions. In U.S. frames in the perimeter zone are only the seismic elements, and the columns inside the building are designed as the gravity columns which support only the weight of the building. In our previous research, it is clarified that such gravity columns can control story drift concentration during an earthquake. We need more study about the effect of damage control for beams and columns by the gravity columns. We will discuss about the seismic limit capacity of the moment resisting frames when the beams or the columns reach their plastic deformation capacities.

In our previous paper, the possibility of flexural bucking of slender piles in liquefied soil was presented, and the buckling stress for the AIJ design code is estimated. Then the boundary conditions were assumed to be pinned support, but in the real structures, the pile heads will move laterally during earthquake. This paper describes the evaluation of the buckling length of slender piles with roller supports on the pile head when the soil liquefies and then the distribution of the coefficient of the subgrade reaction is assumed to be unified or triangular. The relationship between the buckling length of the slender piles and the soil-pile interaction is presented.

Our previous papers clarified the flexural buckling load for H-shaped compression members with the eccentric braces, which are located on the center of their length axis. Then, it was assumed that the non-structural members were used as the bracing. On the other hand, if the roof with any flexural stiffness can be jointed directly to the compression members, it is possible to use it as the bracing. In this paper, the flexural buckling behavior with torsion for H-shaped compression members is presented, and the relationship between the buckling load and rotational stiffness of the roof is estimated.

My previous papers have clarified the effect of the column stiffness and strength for drift concentration of the two story braced frames. The column can have distributed the shear force on each story over height and the story drift concentration is restraint, if it keeps elastic. The equations of the drift concentration factor for the column pinned bases have been developed from the equilibrium conditions of the frames subjected to lateral force. This paper clarifies the mechanism of the two story braced frames with the fixed column bases and shows the equations of the drift concentration factor and the column moment demand.

This paper clarifies the influence of web deformation on the flexural buckling load of H-shaped compression members with eccentric braces at the center of their length axis. In the previous papers, it is assumed that the web deformation of the compression members is restrained in order to have the stiffeners at their joint between braces and members, but a form of joint becomes complicate and constructive efficiency decrease. In this paper, the buckling load is developed by the energy method and confirmed by the elastic eigen-value analysis, and the rigidity demand is evaluated using inelastic large deformation analysis.

When slender steel piles beneath buildings experience high axial compression forces as a result of vertical loads increased by P-Δ effects with inertia forces acting on the buildings and then the soil liquefies, buckling of the piles may occur even thought they are restrained laterally by the liquefied soil. This paper describes the evaluation of the buckling length of slender piles in liquefied soil with the unified and triangular distributions of the coefficient of the subgrade reaction. The relationship between the buckling length of the slender piles and the soil-pile interaction is presented.

Columns in concentrically braced steel frames are generally designed for axial force and column moment demands do not affect the member sizes. If no column flexural stiffness is provided, a soft-story mechanism may occur in a braced frame as soon as the braces in one level reach their strength. In a previous paper, the effect of the column flexural stiffness on two story braced frames with pinned column bases was quantified using direct mathematical formulation, frame push-over and dynamic analyses. This paper evaluates the effect of column base fixity, as well as column stiffness and strength, on drift concentration in two story braced frames.

The authors have proposed the concept of ductile truss structures replacing critical members to buckling-restrained braces. However, in case of seismic retrofit for existing truss structures, effective buckling restrain method for existing members are required. In this paper, buckling restrain retrofit method using outer-tube and in-filled mortal in-between is proposed, and tested under elasto-plastic compression conditions. Their performances are compared with tubes without restrainer or mortal in-filled tube, and their buckling behaviors are studied by numerical analyses.

The previous paper clarified the demands of lateral stiffness and rotational stiffness for the eccentrical lateral support to prevent the flexural buckling of the compression member. The required properties for the lateral support is not only the stiffness but also the strength, and especially, for the eccentrical lateral support, both of the lateral strength and bending strength are required. This paper evaluates the strength demand equivalent to immovable lateral supports, and the inelastic large deformation analysis and the loading test of compression are performed to confirms the effect of the eccentrical support.

In this study, the braces used as lateral supports are eccentrically jointed to the compression members in their sections. The buckling load of the members with eccentric support is calculated by the energy method and the elastic eigen-value analysis. In the modeling, the braces are replaced by lateral and rotational springs. This paper evaluates the rigidity demand equivalent to immovable lateral supports and also confirms its effect using inelastic large deformation analysis.

Column sizes in concentrally braced frames are generally controlled by axial forces since elastic moments due to code seismic loading are generally small. However, if no column flexural stiffness and strength is provided, then a soft-story mechanism is likely to occur when the strength of one story is reached. This paper evaluates the effect of column flexural stiffness on the behavior of a two story braced frame using push-over and dynamic inelastic analyses. Equations for estimating the likely concentration of drift in a specific story, as well as the expected column moment, are developed.

In recent years, stainless steel is superior in fire and corrosion resistance to ordinary steel, and is widely used as a thin walled member in the structure. Its material characteristics are considerably clarified, but the structural characteristics such as tube branches are not sufficiently studied. In this paper, the structural behaviors of the thin-walled stainless steel tubes with X branch joints are investigated by both the experiment and the FEM analysis. Expanding the concept of a ring-model, yield strength and ultimate strength of the branch joint are estimated.

In the previous paper, we clarified that in the frame structure lateral deformation of the beams connected to columns is restricted by those columns, and it is possible to reduce these buckling length Then we assume that boundary conditon of these beam is warping fixed. But in the case of beams connected to H-shaped column, the torsional rigidity of beam-to column joint is small, so we can hardly expect effect of warping restraint at the edge. In this paper, we investigate the lateral buckling length of the beams prevented warping deformation by beam-to column joints

Lateral buckling of H-shaped beams often represents a limiting factor in their bending performance. So we proposed the new methods to improve a lateral buckling strength of H-shaped beam. In this paper, we propose the structual member to consist of a pair of parallel web plates and flanges having prescribed width on both edges of the web plates. This double-web steel member enables to increase torsional rigidity and lateral buckling strength greatly. We clarified quantitatively the effect of this device to lateral buckling behavior by the results of experiments and theoretical analysis.

In the present study, we clarified quantitatively the effect of the torsional stiffening device as the steel pipe to the web of H-section by the results of the experiments and the theoretical analysis. And we proposed the another method to improve a lateral strength of H-shaped beam. The method is to add the steel pipes connected to the web and flanges of the H-section. This enables to increase torsional rigidity and lateral buckling strength greatly and it is possible to set up the web opening. We confirmed validity of the proposed device.

本研究で設計・製作したピエゾ複合センサの出力特性を計測するロボットSALLYは，センサ1種類の計測時間は約20分であり，測定員2人で1日に24種類のセンサ出力測定が可能である．仮に30種類のセンサ出力を測定する場合でも延べ日数で1.2日×2人＝計2.4日で計測でき，鉄骨試験体を用いる実装試験と比較して人的コストは1/18になることが証明された．これまでに鉄骨の試験により，センサ出力特性計測を実施したのは板厚2.0 mmのA型センサのみであるが，このセンサでは特性計測ロボットと実装の両試験において変位量とセンサ出力の関係は同様であった．また，FEM解析と実装試験の結果ピエゾ複合センサはベース金属板の厚さや形状により溶接接合部を想定した破壊時のセンサ出力状況が異なることが明らかになった．SALLYによる引張試験と圧縮試験においては，A型センサ，B型センサともに板厚1.6 mmと2.0 mmの両ピエゾ複合センサで比較的安定した計測結果が得られ，変位量8 ～10 mm近傍の時に大きなセンサ出力が認められた．一方，板厚2.0 mm のA型センサの実装試験結果においても，変位量8～11mm近傍でセンサ出力が生じた．目標とする変位量5 mm以上10 mm未満の範囲において，ロボットと実装の両試験でセンサ出力を確認することができたことから，本センサの信頼性が証明されたと思われる．センサの信頼性や特性を検証するためには，定量的に多数のセンサ出力特性を計測できるロボット開発が重要であり，将来的に実用化が強く望まれる分野であると思われる．構造物の健全性の長期計測を可能にするセンサ開発および簡易モニタリング技術の構築は非常に重要な課題であり，今後も地道に計測システムの構築や計測技術の向上のために努力したい．

Concrete floor slabs are attached to most of beams in buildings, and it has been considered that they are highly effective in restraining for local buckling and lateral buckling of H-shaped beams during large earthquakes. However, during earthquakes, the concrete slab is also subjected to large cyclic stresses, and its stiffness and bearing capacity decrease gradually through a mechanism in which the stiffness and bearing capacity decrease significantly in tension and recover in compression. On the other hand, the deformation due to local buckling and lateral buckling of H-beams by the floor slab was evaluated with high accuracy in terms of the restraining effect and the ultimate bearing capacity and plastic deformation capacity of beams and columns.

To establish a seismic design method of pile foundations for strong earthquakes, pile behavior in ultimate limit state was investigated by both geotechnical engineering and structural engineering. For this purpose, geotechnical centrifuge tests, static loading tests and numerical analysis were performed. The shaft resistance along a pile under combined horizontal and vertical loadings, effects of bending stiffness of a footing beam and pile tip’s support condition on pile stress in a group, pile settlement under cyclic loading, moment-curvature relations and shear capacities of precast and cast-in-site concrete piles, the ultimate strength of steel piles considering the M-N interaction curve according to design criteria and elasto-plastic buckling strength and pile behavior in ultimate limit state were investigated.

In the design of steel structures, composite effects by stud shear connectors are generally measured using ordinary push-out tests. Furthermore, based on those results, the evaluation formulae of the ultimate shear strength are constructed in the design guidelines. However, a concrete slab is subjected to reversed stress during an earthquake, whereas existing tests consider only compressive stresses on the concrete. The mechanical behavior in existing structures thereby might be different from those under compressive force alone. This research therefore proposes a component model in composite beam modeling the stress in actual buildings. In conclusion, results show that the ultimate shear strength is considerably lower than that under compressive stress. Consequently, this report presents equations to assess structural performance precisely considering various influential factors of composite structures.

The estimation method of the steel pile’s ultimate strength in the liquefied soil collapsing due to the significant earthquake is suggested. However, there are some cases, in which the steel piles do not fail and can carry the dead load of the building due to the seismic motion. On the other hand, the steel pile, which has accumulated the damage due to long period earthquakes, might collapse when it experiences the subsequent massive earthquake. In this research, the centrifugal tests are conducted to clarify the steel piles' collapse behavior in the liquefied soil subjected to the multiple earthquakes. Moreover, the steel pile’s ultimate strength and cumulative damage estimation are estimated by numerical analyses.

This study aims to elucidate the damage mechanism of the earthquake caused by the space structure used as a shelter at the time of a disaster and to propose a damage control method.Pushover analysis and seismic response analysis using several analytical programs revealed that the damage of the bearing part progresses toward the center frame from side frame.Moreover, It was confirmed that the base shear coefficient of the bearing when it is damaged is influenced by the shear stiffness of roof and tie beams. Increasing the shear stiffness of the tie beam, the base shear coefficient at the time of damage to the bearing part can be increased.In addition, we confirmed that the horizontal and vertical response of the roof can be controlled by seismic isolation of the bearing part, and safety of the space structure against earthquake can be secured.

Performance-based seismic design requires engineers to develop structural systems which reliably control damages with respect to not only their location but also their extent as engineers expect in a design stage. Beam-yielding mechanism is seismic design concept which is fundamental and is adopted by most of buildings. However, seismic responses of these buildings are subject to types of ground motions so that unexpectedly large damage may occurs. This research proposes a new structural system which reliably control structural damages: A simple connection is applied to a column to control stress distribution and additional structural system is attached which reduces concentration of story displacement.

In the steel frames, the column base is allowed to yield after beam yielding subjected to large earthquake in Japanese design codes such as “The Building Standard Low of Japan” by Building Center of Japan. If the frames have unexpected seismic horizontal force, the soft story mechanism may occur. To prevent the plastic collapse of the column on 1st story, our previous paper suggested the new column support system on 1st story, which consist of the reinforced concrete downside column and the steel topside column. In this paper, the virtual work method is applied to estimate the damage distribution and the collapse deformation capacity of the steel moment resisting frames with dampers and these support systems, and the shear and axial demands the column joints on 1st story are clarified.

In the previous papers, when slender steel piles beneath buildings experience high axial compression forces as a result of vertical loads increased by P-Δeffects with inertia forces acting on the buildings and then the soil liquefies, buckling of the piles occurred even though they are restrained laterally by the liquefied soil. In the real structures, the pile is subjected to the lateral and axial force during earthquake. This paper estimates the ultimate strength of slender piles in liquefied soil when steel pile subjected to vertical and horizontal load. The relationship between the axial force and the flexural moment of the slender piles and the soil-pile interaction is presented.

There are some differences in the steel structures from the view of seismic designs between U.S.and Japan. Japanese typical frames are spatial moment resisting frames. U.S. frames are the perimeter frames, and the columns inside the frames are designed as the gravity columns which support only the weight of the buildings. Such columns may divide the shear force over the height of the frame and work as the damage control systems. This study clarifies the drift deformation concentration for the standard steel moment resistant frames in U.S.and Japan. The equations for the drift concentration are developed under the equilibrium conditions, and compared with the push over analyses results.

Field investigation after recent earthquakes has shown that damage to foundations and superstructures located in similar soil profile could vary. For example, some foundations were damage without significant damage to their superstructures, while some superstructures collapsed without significant damage to their foundations. Such a difference in damage might have been induced partly by the effects of soil-pile-structure interaction and suggests that the effects of dynamic soil-pile-structure interaction should be properly taken into account in seismic design to mitigate damage to superstructure response and pile stresses. In this study, therefore, centrifuge model tests, large shaking table tests, and numerical analysis were conducted, to estimate dynamic soil-pile-structure interaction in various seismic loading conditions and to investigate possibility of new foundation systems. The test results and analysis have shown that (1) The combination of earth pressure, friction and inertial force is affected by the relation between foundation displacement and ground displacement, the height of non-liquefied crust layer, and the relation of natural period of superstructure and ground; (2) The subgrade reaction within a pile group in non-liquefied ground is larger in the leading piles than in the following piles, while that in liquefied ground is larger in the outside piles than the inside piles. As a result, the horizontal load is the largest in the leading piles in non-liquefied ground but in the outside piles in liquefied ground; (3) Buckling stress is estimated by buckling length, soil stiffness and support condition. The slenderness ratio proposed in this study corresponds to that indicated in the guideline for steel structures; (4) Not only soil-pile-structure response but also pile stress is affected such parameter as; predominant period of input motion, natural periods of superstructure and ground, occurrence of liquefaction, presence of foundation embedment. The foundation embedment decreases the pile stresses in non-liquefied ground but increases pile stresses in liquefied ground.

Effects of soil-pile-structure interaction on pile stresses are studied based on large shaking table tests on pile-structure models with and without embedded foundations that are constructed in dry and liquefiable sand deposits. The test results have shown the following : (1)The horizontal subgrade reaction of piles in liquefied soils increases in such a way that the piles are pulled by the soil on the extension side where the reduction of pore pressure occurs. Such mechanism is quite different from that occurring in dry sand where horizontal subgrade reaction is always induced by the increase in earth pressure on the compression side of the pile. (2)If the natural period of the superstructure, T_b, is less than that of the ground, T_g, the ground displacement tend to be in phase with the inertial force from the superstructure, increasing the shear force transmitted to the pile. In contrast, if T_b>T_g, the ground displacement tends to be out of phase with the inertial force, restraining the pile stress from increasing. (3)If soil liquefaction occurs, near surface soil may push the foundation, resulting in an increase in pile stresses. The higher the foundation rigidity, the larger become the pile stresses. The increase in axial force in this case cannot be estimated from the equilibrium of the overturning base moment, as the center of moment equilibrium becomes lower with the development of soil liquefaction. (4)The pile stresses estimated by the pseudo-static analysis, assuming that the maximum moment is equal to the sum of the two stresses caused by the inertial and kinematic effects if T_b<T_g or the squire root of the sum of the squires of the two if T_b>T_g, are in good agreement with the observed ones regardless of the occurrence of soil liquefaction.

This study is projected for the purpose of collecting of the data on buckling strength and ultimate strength of single layer lattice shells with optional shapes. The outlines for the research results in 2002 and 2003 are shown below. Shape optimizations of single layer lattice shells were carried out for maximizing the linear buckling load and minimizing the difference between the maximum and minimum lengths among the specified members. As a result, while taking the linear buckling loads into consideration, the optimal shapes with few kind of member length were obtained. Smooth optimal shapes could be obtained by modeling the lattice shells using tensor product Bezier surface. The buckling behavior of HP (Hyperbolic Paraboloidal) lattice shells under uniform loadings was examined using the static elasto-plastic buckling analysis. HP lattice shell is a surface with a negative Gauss curvature. The initial yield load and the ultimate load were expressed in terms of column buckling strength, and the concept was applied to estimate the initial yield load and the ultimate load of HP lattice shells. In addition, the effects of loading imperfection and geometrical initial imperfection on the buckling behavior were made clear. On the single layer lattice shells with dome shape, the earthquake response behavior and the dynamic buckling behavior were examined. The CQC (Complete Quadratic Combination) method of response spectrum analysis was used. The response acceleration subjected to horizontal earthquake motions were evaluated. Based on the result, the static earthquake load for lattice dome was proposed. On the dynamic buckling analysis, the step wave and single pulse wave were adopted as input waveforms, the analysis method was the time history non-linear response analysis. The effects of the half subtended angle of the dome and the input direction on the dynamic buckling behavior were examined.

The purpose of this study is to investigate the ultimate strength of single-layer latticed domes under the influence of the geometrical imperfections and loading conditions. To examine the fundamental elasto-plastic buckling behavior of the dome without geometrical initial imperfections, the elasto-plastic analysis is carried out. Next, the buckling behavior of the domes with geometrical initial imperfections is examined. Then we carried out the model experiment of span 4.6m. Loading types are concentrated load, one-side uniform load and uniform load with additional concentrated load. As a result, the buckling load of the domes reduced considerably by the existence of the additional load and the initial imperfections. Summaries of the results obtained may be as follows. The elasto-plastic buckling behavior of the rigidly jointed single-layer latticed dome is estimated by the slenderness ratio of the dome lambdas. For the domes without geometrical initial imperfections, for the domes with is <0.80, the elasto-plastic buckling load is smaller than the elastic buckling load, And these domes are collapsed by general buckling. For the domes with 0.80 < ls < 1.0, the domes are collapsed by node buckling. For the domes with geometrical initial imperfections, as the value of ls increases, the elasto-plastic buckling load decreases. Especially, the elasto-plastic buckling load of the dome which is collapsed by node buckling is greatly influenced by geometrical initial imperfections. The elasto-plastic buckling load is estimated by using Modified Dunkerley Formulation as the function of lambdas as well as the function of LAMBDA.

本研究ではH形鋼梁の耐力を低下させる要因となる局部座屈,横座屈の連成問題について検討している。現状の設計基準では局部座屈については幅厚比制限を,横座屈については細長比制限を個別に設けることで部材の設計耐力を規定している。しかし,この二つの座屈現象が連成して生じることは一般的にも認識されつつあり、両座屈の相関性が座屈耐力,変形能力に大きな影響を与えるものと思われる。そこで局部座屈と横座屈が連成するH形鋼梁を対象とし,静載荷実験を行った。試験体は連成座屈は局部座屈が先行した後,横座屈が生じる場合と局部座屈が先行しつつ,局部座屈波形が発声する細長比λyが60〜80,フランジ,ウェブ幅厚比がA〜Cランクに相当するH形鋼梁を選択し,このような連成座屈する梁については支配的な座屈現象を見極め,最大耐力後の崩壊メカニズムを把握した。さらに有限要素法による弾塑性大変形解析を行い,局部座屈と横座屈とが連成するH形鋼梁の塑性変形性能及び最大耐力後の劣化勾配を細長比,幅厚比の観点から定量的に把握した。細長比が等しくても,幅厚比の違いによりその崩壊性状は異なり,また変形性能が同程度の梁でも主たる崩壊性状が横座屈の場合,局部座屈と比較して耐力劣化勾配が急激になっている。そして崩壊性状の変化は梁の応力分布にも違いが生じることから,座屈発生後の局所的な応力集中する位置が異なっている。部材の形状による崩壊形式,塑性変形能力,耐力劣化勾配率の違いを幅厚比,細長比の観点から体系的に整理し,連成座屈を生じるH形鋼梁の保有耐力評価の指標とした。しかし、このようなH形鋼梁のエネルギー吸収能力は幅厚比従来の幅厚比,細長比では一義的に評価することはできないため,今後新たな指標の提示が必要となる。

長周期地震動を受ける高層建築物における杭基礎の液状化地盤上の終局メカニズムの解明

More details Close

高2011年3月11日に発生した東北地方太平洋沖地震では，震源地から300km以上も離れた東京湾沿岸埋立地でも広範囲にわたり地盤が液状化し，上屋構造がほとんど無被害であっても建物が傾き，建て替えや補修を余儀なくされた。その要因の一つとして液状化による杭基礎の破壊が挙げられている。これまでの地震動であれば液状化しない地盤であっても，今回の地震動は，継続時間が長く，地盤の間隙水圧比が徐々に上昇し，液状化に至った。さらに，長周期成分が卓越し，高層建築物の上層階では数ｍの水平振幅を何回も経験した。中低層建築物に比べて，高層建築物ではこのような水平振幅によるP-効果に伴う転倒モーメントが非常に大きく，地下数十mの長さとなる杭基礎には設計時に想定していない曲げモーメントと変動軸力を生じてしまう。現行の杭基礎の耐震設計では，地盤による杭の水平変形拘束に期待し，杭の曲げ座屈崩壊の可能性は検討されていない。しかし，地盤が液状化し，地盤の水平抵抗が急激に低下すれば，杭基礎は曲げ座屈を生じるため，鉛直支持力を喪失し，上屋構造である高層建築物が倒壊する危険性がある。本研究では，これまで研究事例のない長周期地震動を受ける高層建築物の杭基礎の鉛直支持力の喪失と上屋構造の連鎖的な倒壊現象を実証し，地震動の特性と建築物の被害を予測する。さらに，このような杭基礎の終局耐力設計法を提案する。
激震時に柱の降伏を防ぐ柱脚機構を有する鉄骨ラーメン構造の終局設計法の確立

More details Close

一般的な中低層鉄骨ラーメン構造物では，上屋構造の柱，梁に鋼構造部材，基礎梁にRC部材が用いられ，柱脚には埋め込み型柱脚，露出型柱脚等の工法が用いられる。前者の工法は柱脚の回転剛性が高く，柱脚固定に近いため，最下層の水平層剛性が高く，層間変形角が小さくなるものの，上層に比べて柱の脚部と柱頭での作用曲げモーメントのバランスが悪く，脚部の作用曲げモーメントは柱頭に比べて大きくなり，脚部で降伏してしまう。鉄筋の納まり上，基礎梁の断面を大きくするか，基礎梁にハンチを設けなければならない。さらに，鉄骨建て方を基礎梁の工事の前に行わなければならないため，鉄骨部材の製作時間が十分でなく，その間の工事工程が遅れることも少なくない。一方，露出型柱脚は半剛接合となるため，柱頭の曲げモーメントが大きくなるだけでなく，最下層の層間変形も大きくなることから，この層の柱断面を大きくするか，柱脚を弾性固定金物等で基礎梁に緊結し，固定度を上げる必要がある。多くのアンカーボルトが必要となり，厳しい施工精度が要求されるとともに，基礎梁鉄筋との納まりが複雑となる。いずれも，最下層柱の降伏は避けられない。柱梁耐力比が大きければ，梁が柱よりも先行して降伏するものの，塑性変形性能の小さい柱が梁よりも先にその塑性変形限界に達し，耐力低下を起こす2)。軸力の大きい最下層柱で塑性ヒンジ回転量が部材の安定した塑性変形の限界に達し，耐力低下を生じれば，構造物の倒壊に至る可能性がある。E-Defenseによる実大4層鉄骨ラーメン構造物の倒壊実験では，建築基準法に準拠した構造物に1995年兵庫県南部地震JR鷹取駅記録の100%の地震動を入力した際，最下層柱の脚部及び柱頭で局部座屈を生じ，最下層に損傷集中したため，構造物は倒壊した。そこで，関連論文1)3)4)では図1(c)に示すようにRC基礎梁からRC柱を立ち上げ，上部鉄骨柱と下部RC柱を簡易接合し，鉄骨支点部で地震時の曲げ応力の反曲点とする新しい柱脚機構を提案した。この機構は，柱脚が基礎梁と同様，RC構造であり，高い固定度を有する一方，上部鉄骨柱と下部RC柱の接合はベースプレートによるシアキャップとアンカーボルトの緊結とし，鉄骨柱支点部での回転を許容する。この鉄骨柱支点部には，柱の作用せん断力にはシアプレートで抵抗し，圧縮力とせん断力はRC柱の頂部に設けたシアプレートで伝達させ，軸方向の引張力はアンカーボルトで伝達させる方法とする。鉄骨柱支点部の位置を高さ方向に調節することで，最下層の水平層剛性や柱の曲げ応力を制御できるため，従来の柱脚とは異なり，最下層のRC柱の脚部と鉄骨柱の柱頭の曲げ応力の比を制御できる。これまで，この柱脚機構を有する鉄骨ラーメン構造の耐震限界性能や最下層柱を弾性保持するための柱梁耐力比，鉄骨柱支点部高さ等を明らかにした。本研究では，鉄骨柱支

柱，梁を全て剛接合した日本型ラーメン構造物が地震時に梁降伏型の損傷メカニズムを形成する場合，優れた耐震性能を発揮するものの，地震後の復旧は困難となる。兵庫県南部沖地震(1995年)では，構造設計どおり梁降伏型の損傷メカニズムを形成した架構でも損傷が著しく，居住者の退去が相次ぎ取り壊しとなった。このように，柱・梁などの構造物全体で地震エネルギーを吸収することで，倒壊は免れるものの地震後の継続使用が困難となる。また，設計では高さ方向の静的地震層せん断力を層せん断力係数の高さ方向の分布Aiを用いて算定するが，地震動により最大層間変形を生じるときの層せん断力分布とは必ずしも相似になるとは限らず，特定層への変形集中、損傷集中を生じる可能性が大きい。一方，外構面を剛接合ラーメン架構，構造物の内部を軸力支持柱(Gravity Column)とした米国型ラーメン構造物では，地震外力を受ける外構面の剛接合ラーメン架構のみが水平外力に抵抗する。そのため，日本型に比べて梁や柱の断面が部材のせいだけでなく板厚も大きくなってしまう。架構内で損傷が生じ，特定層に層間変形集中が生じようと場合，剛接合ラーメン架構に対して弱軸方向だけでなく強軸に向いている柱もあるが、これらのH形鋼柱が構造体にとっての心棒となり，特定層への変形集中を緩和する効果を有する。このような心棒柱として構造物内の柱や梁全体に損傷が分散され，特定部材に過大な損傷が集中することを防ぐことができる。本研究では，このような軸力支持柱と呼ばれる冗長部材が鉄骨ラーメン架構の損傷集中抑制効果に及ぼす影響を縮小模型振動台実験及び有限要素法による動的解析により明らかにする。

単層トラス架構において，構造部材に取り付く非構造部材は耐震設計上，座屈拘束材としての効果は検討されていないものの，非構造部材による座屈拘束が可能となれば，座屈長さの低減を図ることができる。一方で非構造部材が取り付くことにより，耐震設計上想定されていない座屈挙動を示すことが考えられる。本研究では非構造部材による補剛効果の定量的な把握を目的とし，このような部材の座屈挙動の把握及び座屈設計法を提案する。

本研究では，基礎構造をも含む架構の統合的な構造特性に着目し，鉄骨構造物における冗長システムが損傷メカニズム及び倒壊時性能に及ぼす影響を明らかにする。これまで検討されていない構造物が保有する限界性能に着目し，冗長システムの構造性能をパラメータとした倒壊時における耐震性能評価（倒壊時性能）を行う。ここで，冗長システムは応力分散機構と機能回復機構を有する機構とする。地震時には構造物内で応力を適宜分散させ，地震後の構造物の残留変形に対して自己修復能力を付与したシステムを開発する。本研究は，従来の研究の知見を総括する応用研究であるとともに上屋・基礎系鉄骨構造物の倒壊メカニズムを統合的に検討した先駆的な研究である。

これまでに液状化地盤における鋼管杭の保有水平耐力及び塑性変形性能の把握を行ってきた。液状化地盤では，地盤による側方流動や地盤水平反力の低下により上部構造物の自重及び慣性力により生じる偶力等の影響によって杭の軸力が大幅に増加し，曲げ座屈を生じる可能性があることを示すとともに，杭頭支持条件が座屈荷重に大きな影響を及ぼすことが明らかにされた。そして，エネルギー法を用いて，液状化地盤をモデル化した杭の座屈荷重式を提示し，現行の設計指針への適用の可能性を示した。一方，杭に作用するモーメントは，一般的に上部構造物からの慣性力の影響により杭頭で最大となり，鋼管杭の場合杭頭局部座屈を生じる。そのため，杭頭での曲げモーメントを低減させる目的で，半剛接杭の開発が行われ，実用化されているものの，液状化地盤では上記のような不安定現象を引き起こすことから，適用範囲は限定されている。そこで，本研究では，液状化地盤における高靭性鋼管杭の限界状態を明らかにし，その崩壊時性能の向上を目的として杭頭半剛接合杭の開発を行うとともに，設計に適用できる性能評価を行う。

地震外力等を受ける空間構造物において，通常，非構造部材が構造部材の座屈拘束材として考慮されておらず，架構の耐震性能に寄与していない。非構造部材は構造部材に比べて，断面剛性及び耐力が小さいものの，補剛材に要求される性能は構造部材の性能の数%程度と小さい。そのため，屋根折板等のように材長方向に連続的に取り付く非構造部材が構造部材に直接取り付く場合，座屈拘束材としての活用は十分考えられる。本研究では，空間構造物において材長方向に連続的に取り付いた屋根折板が，図に示すように偏心補剛材として適用された場合の座屈性状を把握するとともに，非構造部材による拘束効果を考慮した構造部材の座屈長さを提示する。

本研究では，地震外力を受けるせん断抵抗型ブレース構造物の損傷集中の抑制を目的として，架構内に弾性柱材を配置したブレース架構を提案し，その耐震性能を評価する。本架構は，その水平初期剛性及び降伏耐力をブレース材に期待し，ブレース材降伏後の層間変形抑制に柱材が働く機能分離型の架構である。そのため，ブレース材は履歴エネルギー吸収能力に優れた座屈拘束型ブレース材等を想定し，柱材はあくまで架構内でredundancyとして，大地震時においても弾性を保つものとする。米国の構造物では建物の自重のみを支持するgravity columnをこのような柱材として捉えることもでき，耐震性能に対するredundancyとして再評価すべきであるとの考えもある。本研究では，このような架構の耐震性能評価として，１）架構の塑性変形倍率と層間変形集中率との関係，２）層間変形集中を抑制する上で必要とされる柱材の曲げ剛性と曲げ耐力との関係を把握する。

性能設計法の導入に伴い，杭基礎においても塑性変形性能等を明確にし，想定地震動に対して適切な性能を保有する必要がある。しかし，地震時の液状化地盤では杭の曲げ座屈に対する地盤の拘束効果がほとんど喪失するにも関わらず，現行の設計指針では細長比制限等を規定していない。本研究では，高い靭性を有する鋼管杭の適用により，液状化地盤における基礎構造物の耐震性能を確保し，設計法の確立を目的としている。上部構造の自重及び水平変形に伴う偶力による圧縮荷重を受ける鋼管杭の座屈荷重を理論的に求め，数値解析によりその妥当性を検証する。

過去の都市直下地震時に埋立地等の軟弱地盤では液状化や側方流動が生じ，杭基礎は図1(a)のような杭頭移動を伴う曲げ座屈を生じる可能性が示されている。このような杭の崩壊挙動は上屋構造の慣性力，曲げ変形による偶力，そして基礎梁による回転拘束等，様々な要因に支配される。しかし，杭の崩壊による構造物全体の損傷を検討した研究は見受けられない。そこで，本研究では，図1(a)に示すような上屋構造の影響を考慮した鋼管杭を対象とし，杭の崩壊挙動の一つである曲げ座屈に着目し，その崩壊メカニズム及び設計荷重の評価を検討する。
