摘　　要：利用结构有限元分析软件ETABS建立了框架-剪力墙结构三维分析模型,在基础设置FPS摩擦摆隔震装置。计算结果表明,在结构基础设置FPS隔震装置以后,结构的楼层位移有所增大,但沿结构高度分布趋于均匀,层间位移与结构内力都明显减少。对于以弯曲变形为主的高层结构,底部层间位移降低较少而顶部层间位移降低较多。结构顶部柱的剪力在中柱与边柱之间分配趋于均匀。剪力墙的剪力与弯矩分别减少了30%以上。A 3D finite element model for frame-shear wall structure was formulated with ETABS structural analysis software, to investigate the seismic isolation efficiency. It is shown that after installation of the FPS system, the storey drift was increased but tend to be more even along structure height. The inter-storey drift and internal forces was decreased significantly. The reduction of inter-storey drift was larger at structure top but less at base for high-rise building of bending type. The shear force in columns tends to be more even between the interior columns and exteri- or columns. The shear force in wails was decreased by as seismic isolation. high as 30%, which exhibits a significant efficiency of
