摘　　要：本文提出高层框支剪力墙结构地震反应分析的超元法 ,即将每榀框支墙中的上部剪力墙和落地墙简化处理成等效柱 ,底部框架简化处理成等代柱 ,楼板视为深梁 ,将连续分布的质量离散化 ,建立二维空间结构的“串并联质点系”振动模型 ,采用超级单元进行结构的地震作用计算及内力分析。此法计算简便并适用于结构竖向变刚度和考虑楼板变形等情况。The super element method for seismic response of high-rise frame-supported shear wall structure is presented. The authors take the serioparallel distributed mass system as the mathematical model of the two-dimensional structure and assume the upper shear walls to be equivalent columns, the bottom frames to be substitute columns and the floor to be a deep beam. The structure subjected to earthquake is analyzed with the super element stiffness matrices. This method may simply used to the structure with vertically variable stiffness and to the case considering the floor deformation.
