[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，理论上会存在一定的误差，但是通过Pushover分析，可以帮助我们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 out of code high-rise structure, Qingdao Fortune building, Pushover analysis was conducted combined with the elastic and elastic-plastic analysis by using SATWE program and FEM software, ETABS and ANSYS. The results show that, while the elastic plastic analysis does not fully agree with the result from theoretical valuation due to the existence of high order mode shape, the push-over analysis is effective in analyzing failure mechanism and predicting the weakest links of out of code high-rise structure under strong earthquake. Proper detailing can then be carried out to enhance the weakest link in design.
