Abstract:Haihu Sports Center in Xining consists of stadiums, gymnasiums and natatorium. The steel roof of the stadium uses a cantilever triangular pipe girder and single-layer lattice spatial grid structure of the hybridization system and the lower stands uses a cast\|in-situ reinforced concrete frame-shear wall structural system. The basic conditions for structural design were introduced, including the structural selection and layout of steel roof, component cross-section, and treatment measures for key nodes. The static calculation and stability analysis were introduced. The difference between the single steel roof model and the overall model was analyzed and the technical measures to solve the structural cracks and temperature stress of the super-long concrete structure were provided.

Keywords:Haihu Sports Center; cantilever triangular pipe truss; single-layer lattice spatial grid structure;  super-long
