Abstract: The stadium of Kuishan Sports Center in Rizhao is an elliptical-plane stadium with wheel-spoke shaped corrugated cable-membrane structure roof. Due to the plane curvature change of the roof, the distribution of cable force is uneven, which makes the form finding and design very difficult. In the process of design, the bearing capacity and deformation of cable-membrane structure roof were analyzed considering the combined conditions of uneven snow load, temperature and wind load. The seismic performance and joint stress of the steel roof were calculated. The analysis of preventing progressive collapses caused by the broken of key cables and the failure of the key supports are carried out, and the overall stability of the ring truss was also discussed. The calculation results show that the design of roof structure meets the requirements and has a certain safety reserve. 

Keywords:Kuishan Sports Center in Rizhao； stadium; steel roof; ellipse plane； wheel-spoke； corrugated cable-membrane structure
