摘　　要：运用通用有限元软件MIDAS建立了带缝剪力墙和普通剪力墙两种有限元模型,对两种结构的基本动力特性进行了比较研究,并在此基础上对两种结构形式进行了时程分析。研究表明:带缝剪力墙结构体系具有较好的整体性,刚度降低较小,具有与普通剪力墙良好的抗剪承载力。地震设防烈度范围的时程分析表明,受力更集中,使剪力墙更加容易破坏,能满足现行规范的设计要求。Two-store finite element model of SSW and SW is built by MIDAS, then comparison research of basic driving force property of two kinds of structure is carried out with time analysis on two structureal forms as the basis. Result shows the SSW system features good integrity and bearing capacity as well as SW within elasticity range, and less stiffness reduction.The earthquake intensity range time,it is easy to be broken in earthquake, asatisfying standard design demand currently.
