［摘要］湖南省博物館新館采用鋼筋混凝土框架-剪力墻結(jié)構(gòu)，屋蓋采用空間H型鋼桁架結(jié)構(gòu)，屋蓋支承在主體結(jié)構(gòu)中的方鋼管混凝土柱上。主體結(jié)構(gòu)為具有多塔、連體、樓板不連續(xù)等多項平面不規(guī)則的超限結(jié)構(gòu)。采用多種計算軟件對整體模型和單塔模型進行靜力及動力反應(yīng)分析，找出了結(jié)構(gòu)的抗震薄弱部位和薄弱構(gòu)件，并采取相應(yīng)的抗震加強措施。結(jié)果表明，本工程具有較好的抗震性能，能夠滿足抗震設(shè)防要求。

Abstract:The new Hunan Provincial Museum adopts a reinforced concrete structure with a frame-shear wall structure and the H-shaped steel spatial truss structure on the roof, and the roof is supported by concrete-filled square steel tubular columns in the main structure. The main structure is an out-of-code structure with many plane irregularities such as multi-tower, continuous body and floor discontinuity. The static and dynamic responses of the whole model and the single-tower model were analyzed by using a variety of computational software, and the parts and members with weak seismic resistance capability were found out, and the corresponding seismic strengthening measures were taken. The results show that the project has good seismic performance and can meet the requirements of seismic fortification.
Keywords:Hunan Provincial Museum; frame-shear wall structure; H-shaped steel spatial truss structure; out-of-code structure; performance-based design
