摘要
昆明某三层钢框架结构,结构总高度18.7m,最大层高3.6m,采用摩擦摆隔震技术。通过试验,获得了隔震支座的竖向刚度。在SAP2000中,通过合理的参数设置,对该结构进行了罕遇地震弹塑性时程分析。提出了支座在罕遇地震下发生破坏的判断条件,结果显示该结构所有摩擦摆隔震支座在罕遇地震下未发生破坏。
A three story steel frame structure in Kunming adopts friction pendulum isolation technology. The structure height is 18.7m and the maximum floor height is 3.6re,The vertical stiffness of the friction pendulum isolator is obtained by experiment. In SAP2000, through reasonable parameter settings, the plastic time history analysis of the rare earthquake in this structure is carried out. the conditions for the failure of the bearing under rare earthquake are proposed. The results show that the structure of all the friction pendulum bearing is not destroyed under the rare earthquake.
