摘　　要：用杆系-层模型和Wilson-θ法,以及El Centro地震记录,分析不同高度和结构刚度特征值的断层剪力墙的框剪结构地震反应。设定可中断剪力墙的高度的条件,计算表明:可中断剪力墙高度的主要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-storey model, Wilson-θ method and E1 Centro ground motion record, the seismic responses of the frame-shear wall structures with shear wall interruption for different heights and rigidity characteristics are analyzed. The conditions of interruptible shear wall height are established. Calculation results indicate ： the primary factor influencing interruptible shear wall height is the shear force carrying capacity of the frame above shear wall interruption ; with the increase of the rigidity characteristic, the interruptible shear wall height increases. The equation for the rigidity characteristic and the interruptible shear wall height is presented. The height of the structure influences little on the interruptible shear wall height.
