［摘要］西寧海湖體育中心由體育場、體育館和游泳館組成。其中體育場鋼屋蓋采用了懸臂三角管桁+單層折面空間網(wǎng)格雜交結(jié)構(gòu)體系，下部看臺采用了現(xiàn)澆鋼筋混凝土框架-剪力墻結(jié)構(gòu)體系。介紹了鋼屋蓋的結(jié)構(gòu)選型及布置、構(gòu)件截面、關(guān)鍵節(jié)點的處理措施等結(jié)構(gòu)設(shè)計基本情況。介紹了靜力計算和穩(wěn)定性分析內(nèi)容，對比分析了鋼屋蓋單體模型與總體模型的差異，給出了解決超長混凝土結(jié)構(gòu)裂縫和溫度應(yīng)力的技術(shù)措施。

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
