Zhongxiang Cultural Complex Project is composed of four venues.The architectural design of Science and Technology Museum is dominated by tall space,and the structure has the characteristics of large-span and large cantilever.The large-span cantilevered area around the roof of the Science and Technology Museum adopts a steel structure suspension system composed of steel frame+steel truss+prestressed cable.The roof is a two-way plane steel truss with prestressed cables,and the load of the lower suspension area is transmitted through the high-strength steel tie rod at the end of the truss.Buckling analysis was carried out on the strength and stability of the suspension system.The anti-progressive collapse ability of the suspension system and the complex joints were analyzed by special analysis of anti-collapse analysis and finite element analysis of joints.The results show that the design of the project is safe,economical and reasonable.
