[摘要] 基于ABAQUS软件，对某实际工程的超限高层结构进行了罕遇地震弹塑性时程分析，归纳了结构超限情况，介绍了有限元合理建模方法与隐式分析的收敛问题，及前后处理的相关技术，总结了计算参数取值，对该结构的抗震性能从结构整体指标和构件性能指标两方面进行了评价，为工程设计与实践提供了有益的参考和借鉴。

Abstract: Elasto-plastic time-history analysis of an out-of-code tall building under rare earthquake was carried out based on finite element analysis software of ABAQUS. The out-of-code information was concluded firstly, and then the reasonable method of finite element modeling, the convergence of implicit analysis and the relevant technique of pre- and post-processing was introduced. The summation of the parameter selection for the analysis was also put forward. The seismic performance of the structure was evaluated in two aspects, the whole structure performance indicator and the member performance indicator. All of these provide a useful reference for project design and practice.
