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.

研究了建筑物基础在地震作用下的结构性能。首先讨论了结构体系的受力平衡条件和基础体系的被动抗力。其次，从地基系统主动抗力的角度讨论了桩与周围土层的协调条件。本文研究了偏心墙框架结构在任意方向地震作用下的扭转反应。研究结果表明，在结构扭转反应分析中，考虑地震动方向是必要的。研究了底层为软土的建筑物的非线性响应。研究表明，第一层最大位移幅值不仅受第一层强度的影响，还受其它层强度的影响。在此基础上，提出了将底层侧移控制在给定范围内所需的建筑物强度 ...更多信息提出了允许的极限。根据地震动基本特征与非线性反应之间的一般关系，考虑能量平衡和地震持续时间，可以合理地定义非线性系统的等效线性系统。为防止钢筋混凝土建筑物在强震作用下发生层间倒塌，定义了层间剪切安全系数。提出了一种钢筋混凝土结构层间位移的预测方法。分析了肋形和搭接长度对无腹筋搭接接头强度的影响。本研究提出了基于能力谱法概念的非对称建筑抗震性能评估程序。该方法利用由抗震设计谱得到的能力曲线和需求谱，可以简单明了地评估建筑物的地震反应。本研究的目的是通过实验研究开洞悬臂剪力墙的变形能力，并对开洞悬臂剪力墙的变形能力的计算公式（桁架-拱模型）进行评价。通过6个平面十字形组合试件的试验，研究了梁柱中节点的破坏机理。所有样本均在接头处失效。节点板中形成的斜向混凝土支柱的压缩坍塌导致节点剪切破坏。然而，对角节点剪力可以由对角支柱周围的混凝土承担。对平面侧阻分布不均匀的钢筋混凝土结构进行了非线性动力反应分析，提出了结构设计中应考虑的扭转反应指标。（中野）减
