［摘要］采用HBTA和ETABS软件对重庆万豪国际会展中心两种结构方案（框架-支撑全钢结构与钢-混结构）分别进行弹塑性分析，并对分析结果进行对比。通过弹性时程分析、静力弹塑性和弹塑性时程分析，对两种方案的弹性和弹塑性性能进行研究。结果表明，两种结构方案均能满足我国《建筑抗震设计规范》（GB 50011—2001）中“小震不坏、中震可修、大震不倒”的设防目标。同时对两种结构形式的抗震性能进行了比较。

Abstract: Elastic-plastic analysis of hybrid structure and steel structure of Chongqing Marriott International Conference Center tower was carried out by HBTA and ETABS. By elastic time-history analysis, Pushover analysis and elastic-plastic time-history analysis, elastic and elastic-plastic properties of two structures were investigated. Results show that both of two structures can satisfy Code for seismic design of buildings（GB 50011—2001）of “not be damaged under frequent earthquake, can be repaired under fortification earthquake and not be collapsed under rare earthquake”. The seismic performance of two structures was also compared.

Keywords: super-tall building; steel structure; hybrid structure; elastic-plastic analysis
