Abstract: Kaifeng Sports Center  Stadium has a novel architectural style. The lower stand of the stadium structure is reinforced concrete structure, and the roof canopy structure is space tube truss structure. Through a comprehensive analysis of the single and overall performance of the steel structure canopy, a structural scheme suitable for the building’s shape was given. The static force, wind load and seismic effects of the structure were analyzed, and key issues such as the overall structure and the long-span roof structure layout and key nodes selection were determined, and a variety of softwares were used to calculate the overall structure. The key nodes were compared and selected, and the typical nodes were analyzed using finite element software to verify the reliability of the nodes. The calculation results can meet the requirements of structural safety. 

Keywords:Kaifeng Sports Center Stadium； steel structure canopy； space tube truss； key node
