摘　　要：西宁海湖体育中心由体育场、体育馆和游泳馆组成。其中体育场钢屋盖采用了悬臂三角管桁+单层折面空间网格杂交结构体系,下部看台采用了现浇钢筋混凝土框架-剪力墙结构体系。介绍了钢屋盖的结构选型及布置、构件截面、关键节点的处理措施等结构设计基本情况。介绍了静力计算和稳定性分析内容,对比分析了钢屋盖单体模型与总体模型的差异,给出了解决超长混凝土结构裂缝和温度应力的技术措施。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.
