断层剪力墙框剪结构地震作用的时程分析

Seismic analysis of the frame-shear wall structures with shear wall interruption by the time-history method

采用杆系-层间模型和弹性时程分析法对不同高度和结构刚度特征值的断层剪力墙框剪结构进行动力分析.该法与振动台实验结果对比,吻合较好.设定了最大层间位移角θmax为可中断剪力墙的条件.计算表明:随着刚度特征值的增加,可中断剪力墙的高度随之增加.给出了两者之间的表达式;结构高度对中断剪力墙高度的影响较小.

Based on the member- relative storey model and linear time - history analysis, the frame - shear structures with shear wall interruption for different heights and rigidity characteristics are analyzed. The result from the method has tallied with those from the shaking table. The conditions that the most story drift angle of interruptable shear wall height are established. The results show that, with the increase of the rigidity characteristic, the interruptable shear wall height increases. The equation between the rigidity characteristic and the interruptable shear wall height is also presented. The height of the structure has small influences to the interruptable shear wall height.
