摘　　要：用杆系-层模型和振型分解反应谱法,分析不同高度和结构刚度特征值的断层剪力墙框剪结构地震反应,设定可中断剪力墙的高度条件.计算表明,可中断剪力墙高度的决定因素为上部框架的抗剪能力,随着刚度特征值的增加,可中断剪力墙的相对高度随之增加.文中给出结构高度和相对高度的表达式,结构高度对相对高度的影响较小.Based on the member-storey model and SRSS method, the frame-shear wall structures with shear wall interruption for different heights and rigidity characteristics are analyzed. The conditions of interruptable shear wall height are established. The calculation results indicate： the decisive factor influencing relative height of interruptable shear wall is the shear force carrying capacity of the frame above shear wall interruption; with the increase of the rigidity characteristic, the relative height of interruptable shear wall increases also. The equation between the rigidity characteristic and the relative height of interruptable shear wall is also presented. The height of the structure influences little on the relative height of interruptable shear wall.
