摘　　要：以某六层框架结构作为分析对象,设置不同刚度的摇摆墙,研究加入摇摆墙前后以及摇摆墙刚度大小对结构内力分布及变化规律的影响。分析结果表明:当框架结构层间刚度不均匀时,对摇摆墙的内力分布和结构受力会产生较大的影响,摇摆墙的剪力、弯矩均随地震强度和刚度比的增加而增加,摇摆墙的加入减小了框架部分的地震作用,达到防止出现薄弱层的作用。This article takes the six story frame structure adding different stiffness wall as the analysis object. The effects of adding the rocking wall and the wall stiffness variation on the structure internal force distribution and the changing rule are studied. From the analysis results it is concluded that： when the interlayer stiffness of the framework is uneven, it has great influence on the internal force distribution of rocking wall and the force of the structure. The shear force and the bending moment of the rocking wall increase with the increasing of earthquake intensity and stiffness ratio. With the addition of the rocking wall, the seismic effect of the frame part decreases, and the emergence of the weak layer is prevented.
