Abstract:The steel roof of gymnasium in Haihu Sports Center in Xinning  adopts the rib ring spatial truss-single-layer folded surface spatial grid structural system. The lower structure is reinforced concrete frame-shear wall structure. The structure selection and structure layout of the roof were mainly introduced. Through the method of multi model calculation and analysis,  the structural design was analyzed and the stability of the roof was verified. Application of up to 25 cast steel joints provides engineering practical cases for similar projects.

Keywords:Haihu Sports Center; steel roof; rib ring spatial truss; single-layer folded spatial grid structure; cast steel joint
