[摘要] 太原博物馆主体结构由Tl~ T5单塔和各层连廊组成。其中Tl。T5单塔采用钢框架一钢筋混凝土剪力墙组合结构，连廊采用隔震支座与两侧塔楼进行弱连接。采用MIDAS/Gen软件对单塔进行罕遇地震作用下的静力弹塑性分析（Pushover分析），考察结构塑性发展顺序，找到结构薄弱部位，评估性能目标的实现情况，为设计提供依据。分析结果表明，针对该工程设定的性能目标得到了实现，结构的安全性可以得到保证。

Abstract:Tai Yuan Museum is composed of Tl～T5 towers and joint galleries. All towers are steel frame-shear wall structures, and joint galleries are weakly connected with seismic isolation bearings between two towers. The tower was modeled to conduct the static elastoplastic analysis under rare earthquake using MIDAS/Gen software. The appearing order of plastic hinges, the weak parts of structure and the objective of performance design were calculated and analyzed, which can provide foundation for design. The results show that the objective of performance design is realized for this
project, and safety of the structure is ensured.
