摘要

为研究大震下结构三维弹塑性地震反应,基于纤维模型,对一个规则、对称的钢筋混凝土框架-剪力墙结构建立三维分析模型,分别在单、双向输入地震动情况下进行了弹塑性地震反应分析,对两种情况下结构顶层位移、加速度、扭转角,基底剪力及各层的最大层间位移角、层剪力、层扭转角等反应进行对比分析。结果表明:在单、双向输入地震动时结构水平方向反应变化不大;双向输入时的结构顶层扭转角时程反应和楼层最大扭转角反应都远大于单方向输入时的扭转反应。
Directed at investigating 3D inelastic earthquake response of frame-shear wall buildings exposed to big earthquake,this paper gives fiber model-based 3D nonlinear analysis model to analyze earthquake response of a regular and symmetrical R.C.frame-shear wall building under the conditions of one-direction inputted and two-directions inputted.The comparative analysis of the results of top story displacement,acceleration,base shear response,maximum story drift ratio,maximum story shear response and story torsional angle proves that the reponse in horizontal direction shows a less change under the conditions of one-direction inputted and two-directions inputted and the torsional angle time histories response at top story and peak value of story torsional angle response under two-direction inputted condition are far more than the ones under one-direction inputted condition.
