含断层剪力墙框-剪结构的楼层地震剪力
|
摘要
在用数值分析法分析含断层剪力墙框 -剪结构地震响应的基础上 ,采用杆系 -层间模型 ,对不同剪力墙高度的剪力墙刚度中断的框 -剪结构模型进行动力分析 .通过输入 EL- Centro地震波 ,将所得到的结构最大位移反应和楼层剪力与振动台的试验结果进行对比 ,结果吻合较好 .文中得出反应点以上的截断剪力墙 ,比在其下截断对于框 -剪结构的抗震和受力更为有利的结论 .
The present work is based on the numerical analysis of the seismic response of a frame-shear structure containing fault shear wall. By adopting member-relative storey model, a dynamic analysis is made on a model of frame-shear structure containing shear wall with stiffness interruption at different heights of shear wall. After inputting El-Centro seismic wave, maximum displacement reaction and floor shear of the structure are obtained and are comparied to the results from test of vibrostand, both results are well-coincided. It is also concluded that truncation of shear wall above inflection point will be favourable to seismic resistance and force condition of the frame-shear structure more than that below inflection point.
