摘　　要：以某大厦实际工程为背景,对其开展弹塑性时程分析,探究该结构体系在罕遇地震下的抗震性能。用DIANA程序建立结构简化模型,选择结构材料的应力-应变关系和单元类型,对原型结构在罕遇地震下的层间位移角和底部剪力进行分析,最后对结构进行整体评价。Elasto-plastic time history analysis on a super high-rise building was carried out in this paper to study the seismic behavior of this structure under rare earthquake. Firstly, the simplified analytical model, the material stress-strain relation and the analytical element style were achieved. The elasto-plastic seismic response of prototype structure was calculated under rare earthquake. The inter-story drift distribution and bottom shear were discussed in detail. Finally the seismic behavior of this building was evaluated based on these results.
