| 摘 要： | 青岛财富大厦是一座复杂的超限高层建筑.设计除利用SATWE程序及ETABS和ANSYS有限元分析程序进行弹性和弹塑性计算分析外,还对结构进行了静力弹塑性分析(Pushover Analysis).研究表明:静力弹塑性分析方法在超限高层结构设计中,由于受高振型的影响,虽然理论上会存在一定的误差,但是通过Pushover分析可以从宏观上发现结构在罕遇地震作用下的破坏机制,从而对可能存在的薄弱部位进行有针对性的加强,提高结构可靠度.

| Abstract: | To investigate the seismic behavior of an ultralimit high rise structure,in Qingdao Fortune center,a Pushover analysis was applied combined with the elastic and elastic-plastic analysis by means of SATWE program and ETABS and ANSYS software.The results show that the elastic-plastic analysis does not fully coincide the result of theoretical valuation due to the existence of high order mode shape,the Pushover analysis is effective in analyzing of the failure mechanism and predicting of the weakest link of ult... |
