【摘要】 借助于有限元软件ETABS对唐山市一隔震设计的医院住院楼进行了地震反应分析,分析中采用了与传统的抗震结构相对比的方案,分析结果表明隔震结构延长了结构的周期,使结构的加速度反应大大减小,同时使结构的位移集中于隔震层,上部结构像刚体一样,自身相对位移很小,结构基本上处于弹性工作状态。更多还原

【Abstract】 With the assistance of the finite element software ETABS,the paper has the seismic response analysis on the inpatient buildings of some hospital with the isolation earthquake design in Tangshan,adopts the scheme compared with the traditional seismic structure.It is shown by the result that the isolation seismic structure prolongs the structural period to reduce the acceleration response of the structure greatly,and to collect the displacement of the structure around the isolation layer,so the upper structure can be the same with the rigid body and self relative displacement is little and the structure is basically kept the elastic state.更多还原
