项目摘要

Structural behavior of building foundation during seismic action is examined. First the equilibrium condition for the forces acting on the structural system and passive resistance of foundation system is discussed. Secondly the compatibility condition for the piles and surrounding soil layer is discussed from a point of active resistance of foundation system. (Kubo)The torsional response of a frame structure with an eccentrically placed wall subjected to earthquake motions with an arbitrary direction was studied. The study has revealed the necessity of considering the direction of ground motions in assessing the torsion response of a structure. (Yoshimura)The nonlinear response of a building with soft first story was studied. The study has revealed that the amplitude of maximum first story drift is affected not only by the strength of the first story but also that of other stories. On the basis of the study, the strength of buildings required to control the first story drift within giv … More en permissible limits was presented. (Yoshimura)Based on general correlations between basic characteristics of earthquake motions and nonlinear responses, an equivalent linear system for nonlinear system could be defined rationally considering the equilibrium of energy and the duration of earthquake. (Kabeyasawa)Story shear safty factor is defined to prevent story collapse in reinforced concrete buildings during severe earthquake. A method is proposed to predict inter-story displacement of reinforced concrete buildings. Effect of rib shape and splice length on the strength of lap splices without stirrups is analytically discussed. (Ichinose)This study presents the procedure for estimating seismic performance of asymmetric buildings based on a concept of the capacity spectrum method. In the method, the seismic response of the buildings can be evaluated simply and clearly by using the capacity curve and the demand spectrum obtained from seismic design spectrum. (Teshigawara)The objectives of this study were to examine deformation capacities of cantilever shear walls with openings experimentally and to evaluate the design equation (truss-arch analogous model), which had been developed to estimate the shear strength of shear walls with openings, for the estimation of the deformation capacities of cantilever shear walls with openings. (Kato)The failure mechanism of an interior beam-column joint was investigated by the tests using six plane cruciform subassemblage specimens. All specimens failed in a joint. The joint failed in a shear through the compressive collapse of the diagonal concrete strut formed in the joint panel. The diagonal joint shear however could be carried by the surrounding concrete of the diagonal strut. (Kitayama)Nonlinear dynamic response analyses of RC buildings having unbalanced distribution of lateral resistance in plan were carried out, and an index to be considered in structural design related to the torsional responses was proposed.

检查地震行动期间建筑基础的结构行为。首先，讨论了作用在结构系统上的力和基础系统的被动抗性的等效条件。其次，从基础系统的主动阻力中讨论了桩和周围土壤层的兼容性条件。（Kubo）研究了具有偏心壁的框架结构的扭转响应，并研究了与任意方向的地震运动。该研究揭示了考虑地面运动方向评估结构的扭转反应的必要性。（Yoshimura）研究了具有柔软第一故事的建筑物的非线性响应。该研究表明，最大第一故事漂移的幅度不仅受到第一个故事的实力，而且还受其他故事的影响。在研究的基础上，控制了GIV内的第一个故事漂移所需的建筑物的力量……提出了更多的许可限制。（Yoshimura）基于地震运动的基本特征与非线性响应之间的一般相关性，可以考虑到能量平衡和地震持续时间，可以在理性上定义非线性系统的相等线性系统。（Kabeyasawa）故事剪切安全系数的定义是为了防止在严重地震期间钢筋混凝土建筑物中的故事崩溃。提出了一种方法来预测钢筋混凝土建筑物的层间位移。分析讨论肋骨形状和剪接长度对没有压力的膝盖剪接强度的影响。（Ichinose）这项研究提出了基于容量谱法概念来估计不对称建筑物的地震性能的程序。在该方法中，可以通过使用能力曲线和从地震设计频谱获得的容量曲线和需求频谱来简单明了地评估建筑物的地震响应。（Teshigawara）这项研究的目标是检查悬臂剪力壁的变形能力，并在实验上开口检查并评估设计方程式（Truss-Arch类似模型），该方程已开发出来，以估算剪切壁的剪切强度，并通过开口估算带有开孔的矮衣壁的变形能力。（KATO）使用六个平面十字形亚摘要样品研究了内部梁柱接头的破坏机理。所有标本在关节中都失败了。该关节因在关节面板中形成的对角线混凝土支柱的压缩塌陷而在剪切中失效。然而，对角线剪切可以通过对角支柱的周围混凝土携带。（Kitayama）进行了计划中横向电阻不平衡分布的RC建筑物的非线性动态响应分析，并提出了与扭转响应有关的结构设计中考虑的索引。（nakano）少
