Design on complex steel structure of Nantong Art Museum
Nantong Art Museum adopts a reinforced concrete frame-shear wall+braced steel frame structure.The structural layout is irregular,such as structural plane irregular torsion,irregular floor slabs,and discontinuous vertical components.The small exhibition hall is arranged in a circular arc fan-shaped shape and adopts a braced steel frame structure.There is a locally stacked corner relationship between the upper and lower small exhibition halls,which vertical components cannot be directly landed.The multistory and multiple conversion steel frame and multistory cantilever steel trusses are used.The steel structure system has the characteristics of complex and irregular positioning,multistory and multiple conversion,large cantilever size of multistory cantilever steel truss,large span steel truss,and large load.Based on the above characteristics of the structure,higher performance goals for important structural components were proposed.Key issues in the design of complex steel structures were analyzed and countermeasures were proposed.The programs such as ETABS,PKPM,SAP2000 were used for overall model analysis and various supplementary analyses,including anti overturning calculation,small exhibition independent model bearing capacity calculation,floor stress analysis,comfort analysis,etc.The calculation results indicate that all indicators of the structure meet the requirements,and the structure is safe and reliable.Structural integrity and stability were ensured by emphasizing structural concepts and structural design.
