摘　　要：针对一个10层框架-剪力墙基础隔震结构体系,考虑框架与剪力墙之间的相互作用,通过改变隔震层刚度及框架与剪力墙的刚度比,分析隔震层对地震波的滤波作用,以及考虑上部结构累积变形与隔震层大位移P-Δ效应,对高层框架-剪力墙结构的整体力学响应进行研究.结果表明:随着隔震层刚度的增加,传递到上部结构底部的加速度频谱幅值逐渐增大.随着框架与剪力墙刚度比增大,层间剪力的分布趋于均匀.上部结构累计变形产生的附加弯矩略大于隔震层本身P-Δ效应产生的附加弯矩.Aimed to the interaction of the frame-shear wall,the stiffness of isolation layer and stiffness ratio be-tween frame and shear wall were analyzed for a 10-stor high-rise frame-shear wall foundation isolation structure. The effect of seismic wave on the seismic response of high-rise frame-shear wall structure was studied by considering the fil-tering effect of seismic wave and considering the large displacement P-A effect of the upper structure and the large dis-placement of the isolation layer. The results showed that,with the increase of the stiffness of the isolation layer,the amplitude of the acceleration spectrum was increased gradually at the bottom of the upper structure. As the stiffness ra-tio between the frame and the shear wall increases,the distribution of interlaminar shear tends to be uniform. The addi-tional bending caused by the cumulative deformation of the superstructure was slightly larger than the additional bending moment produced by the P-A effect of the isolation layer itself.
