【提要】  从理论上探讨了剪力墙中断对框剪结构的影响，并结合实际工程，利用ANSYS软件建立了三维模型，通过地震反应分析的结果，证明了从反弯点中断剪力墙是不安全的，而从剪力墙剪力为零处以上中断则不会对原结构产生明显影响，且减小了结构顶部水平位移及层间位移角,提高结构的整体刚度。

Abstract:The influence of interrupted shear wall on frameshear wall structures is studied.The 3D models of frameshear wall structures with interrupted shear wall in different place are established to calculate their behaviors under earthquake using ANSYS software.The results indicate that interrupting shear wall at the point of moment inflection is not safe enough,while that at the point of shear inflection will not produce the obvious influence to the structure,and it can reduce the movement of the top floor and increase the stiffness of structure.
