水平地震作用下转换层上、下结构侧向刚度比对框支剪力墙结构抗震性能的影响

摘要

针对不同的转换层上、下结构侧向刚度比γ,采用有限元软件ANSYS对转换层设在第1层的14层框支剪力墙结构在水平地震作用下的抗震性能进行了计算分析.研究了水平地震作用下转换层上、下结构侧向刚度比对框支剪力墙结构抗震性能的影响,并对加强落地剪力墙和减少转换层上部剪力墙对框支剪力墙结构抗震性能的影响进行了比较分析.%Based on different lateral stiffness ratio,a sens of 14-story shear wall structures supported on frames with transfer story at the bottom layer are analyzed under horizontal seismic action by finite element program ANSYS. The influence of lateral stiffness ratio on seismic behavior of shear wall structures supported on frames under horizontal seismic action are studied, and the influence of strengthening shear wall linked with the ground and decreasing shear wall on the transfer floor on seismic behavior of shear wall structures supported on frames are compared.
