摘　　要：安徽省地质博物馆建筑造型新颖,平面和立面均不规则,结构设计较为复杂,有较多的结构设计难点,如设计使用年限为100年;半敞开式地下室;矿石展厅东侧最大悬挑达25.4 m;古生物化石展厅和矿石展厅两单体间的连廊及屋顶雨篷等。针对该不规则框架结构,采用了基于性能的抗震设计方法(包括小震弹性计算、中震不屈服构件验算、罕遇地震下的弹塑性分析)。详细介绍了设计参数的选择、计算分析的过程以及对各难点所采取的结构设计措施,可供同类工程设计参考。The structural system of the Anhui Geological Museum is complex. It has an innovative architectur-al design and irregular plane and elevation profiles. There are many challenges in structural design： 100 years of service life, partly opened basement, the large cantilever length （25.4 m in the east of the ore exhibition hall）, the corridor and the skylight between the fossil exhibition hall and the ore exhibition hall. In frame de- sign, performance-based seismic design method was used （ including elastic analysis under frequently occurred earthquakes, un-yielding check of structural components under medium earthquake, static and dynamic elasto-plastic analysis under rarely occurred earthquakes）. This article introduces in detail the selection of design co-efficients, the process of computation and analysis, as well as the structural design methods to solve various problems. The information reported here can be used as the reference for similar projects.
