( East China Architecture Design&Research Institute Co. , Ltd. , Xian Dai Architectural Design Group, Shanghai 200002)Abstract: Expo Performance Center's steel roof adopts large span- space truss system, which is supported on the to Pof the leaning frame of the stand in circumferential direction. The structural system is decided to meet the requirements of architectural outline, usage of the inside space and large suspension load. Roof individual model and structural integral model are both analyzed to make comparison of the structural load-bearing performance and deformation considering the vertical load, wind load, thermal action, seismic action and the impact of the deformation of the sub-structure.
Keywords: space truss; comparison of structure system; analysis model; deformation
