[摘要]辽宁省科技馆是多功能的大型展览馆，钢-混凝土混合框架结构，体型复杂。采用CFX软件对其进行数值风洞模拟，得到了球体、大挑檐、幕墙的平均风压；采用SATWE和MIDAS软件进行整体分析，应用屈曲约束支撑调整结构整体扭转性能，对大开洞部分进行楼板应力分析。分析结果表明，主体结构抗震性能良好，有很好的延性。

Abstract: Science and Technology Museum of LiaoNing Province is a multifunction exhibition building with steel-concrete frame structure system, CFX analysis was used to numerical simulation analysis of the wind load for the data of sphere, cantilever roof and facade. SATWE and MIDAS were used in seismic calculation, buckling-restrained brace was applied to adjust the building torsion behavior, and also we made stress analysis for the slab of all floors. The results show that the main structure has sufficient seismic capacity and ductility.
