【摘要】 主要就异形柱隔震结构进行弹塑性动力时程反应分析,研究异形柱隔震结构的抗震性能。利用PERFORM 3D软件,对高烈度区同样条件的隔震与非隔震结构在罕遇地震下的加速度、位移与剪力等进行对比分析,最后得出在罕遇地震作用下异形柱隔震结构比非隔震结构能大大降低上部结构的地震反应。更多还原

【Abstract】 Isolation structures with specially-shaped columns are analysed mainly elastic–plastic dynamic to study performance of specially-shaped columns with isolation structures.Using PERFORM 3D software,the same condition of isolation and without isolation structures are studied acceleration,displacement and shear under rare earthquake with high intensity.Finally,to without isolation structures,the paper concludes that isolation structures with specially-shaped columns can greatly reduce the seismic response of upper structures under rare earthquake.更多还原
