摘　　要：采用静力弹塑性方法对云南某工程购物中心南区(钢框架结构体系)在罕遇地震作用下的抗震性能进行了分析。结果表明,在罕遇地震作用下,该结构的最大弹塑性层间位移角小于规范的限值;钢框架结构的塑性铰主要出现在梁端;绝大部分钢框架柱处于弹性,只有极少数钢框架柱出现了塑性铰,通过调整设计使得全部框架柱都不出现塑性铰。该工程的设计达到了预定的抗震设防目标。Seismic hehavior of the south part of shopping mall which belongs to a project in Yunnan was studied by static elastoplastic analysis method under rare earthquake. Results indicate that the maximum drift angle of steel frame under rare earthquake is less than the limit value ; most plastic hinges are formed in frame beams ; only a few plastic hinges are formed in frame columns, the frame columns are almost in the elastic stage. By adjusting the design, there aren＇t plastic hinges formed in frame columns. The results indicate that the design of the structure achieves the seismic performance objectives.
