[摘要]遼寧省科技館是多功能的大型展覽館，鋼-混凝土混合框架結(jié)構(gòu)，體型復(fù)雜。采用CFX軟件對其進(jìn)行數(shù)值風(fēng)洞模擬，得到了球體、大挑檐、幕墻的平均風(fēng)壓；采用SATWE和MIDAS軟件進(jìn)行整體分析，應(yīng)用屈曲約束支撐調(diào)整結(jié)構(gòu)整體扭轉(zhuǎn)性能，對大開洞部分進(jìn)行樓板應(yīng)力分析。分析結(jié)果表明，主體結(jié)構(gòu)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.
