Abstract: Spatial truss structure system are adopted in the stadium canopy of Fucheng National Fitness Center. The front fulcrum of truss is connected with the steel column through a spherical hinge support, and the rear fulcrum is connected to the reinforced concrete beam by a pin axis joint. The overall stability of the structure is ensured by setting the circumferential sub-truss and supporting rods. The mechanical characteristics of the structure and key nodes were analyzed by using the finite element analysis software MIDAS and ABAQUS. Analysis results show that stress ratio, deformation and stability can satisfy the requirements of standards, which proves that the structure is rational and safe. 

Keywords:Fucheng National Fitness Center； stadium canopy； spatial truss structure system； static analysis； stability analysis； finite element analysis of joint
