建筑隔震结构地震反应分析
|
摘要
通过建立下部结构—周围土体—隔震层—上部结构整体系统的空间模型,对三里河三区12号地办公楼工程中的隔震结构进行有限元非线性分析,通过模拟系统地震振动响应,对比分析隔震与非隔震结构层间剪力和剪力比,以及验算隔震层隔震垫的水平位移,从而验证隔震技术的有效性。
This paper used FEM to nonlinear analysis the isolating earthshock structure at No.12 plot office building in Sanlihe three district,by establishing spatial model of total system of substructure,surrounding soil body,the isolating earthshock floor and superstructure.With analyzing the system responding to imitating earthshock vibration,the paper compared interlaminar shear and ratio of shear force of isolating earthshock structure with usual structure, and checked the level displacement of nappe rubber brace,in order to proof validity of the technology for isolating earthshock.
