【摘要】 采用经验证正确的钢筋混凝土框架-剪力墙非线性时程分析程序,对提出的算例进行了在单双向地震波输入下结构的弹塑性时程分析,得出如下结论:双向地震波作用下,结构的反应增大,周期略有增加;在双向地震波及扭转地震波作用下,角柱增加幅度可达到20%以上;对顶层的影响较底层大;最大位移出现的时间较单向地震波输入略有滞后。结构底层的层间位移角最大,说明是结构的薄弱环节,应该加强。更多还原

【Abstract】 The nonlinear time-history analytical method for frame-wall structures is developed.Through compared with analytical results and the results of shaking table tests,we can concluded that,the nonlinear analytical method developed in this paper is reliable.The bottom of structure should be strengthened because this part is unsubstantial for the displacement corner is maximal.Compared with the structural response under single seismic wave,the displacement and corner increase under bidirectional seismic wave.This phenomenon is distinct at the top of structure than at the bottom of structure. The period of structure is increased appreciably and the time of maximal peak value is delayed in a way.更多还原
