摘　　要：基于有限元分析软件SAP2000,结合某多层钢结构住宅工程实例,建立抗震和层间隔震结构的有限元模型,运用线性时程分析法对两种结构在多遇地震下的楼层剪力、层间位移、顶层加速度等地震反应进行动力分析,研究多层钢结构住宅层间隔震的规律与特点,验证层间隔震在多层钢结构住宅中的有效性和可行性。Based on the finite element analysis SAP2000 software,finite element models of the non-isolated structure and storey isolated structures are established on a multi-storey steel structure residence.Dynamic analysis of the structures’seismic response including the storey shear,the maximum story displacement and the acceleration of roof are conducted under frequently occurred earthquake by using liner time-history analysis method.The rule and characteristics of the multi-storey steel structure residence with interlayer seismic isolation are studied.The feasibility and validity of interlayer seismic isolation in multi-storey steel structure residence is verified.
