［摘要］西寧海湖體育中心體育館鋼屋蓋采用肋環(huán)形空間桁架+單層折面空間網(wǎng)格結(jié)構(gòu)體系，下部結(jié)構(gòu)為鋼筋混凝土框架-剪力墻結(jié)構(gòu)。主要介紹了鋼屋蓋的結(jié)構(gòu)選型及結(jié)構(gòu)布置。采用多模型的計算分析方法，對結(jié)構(gòu)進行設(shè)計分析并驗證了鋼屋蓋的穩(wěn)定性。多達25支管的鑄鋼節(jié)點的應(yīng)用，為類似工程提供了工程實際案例。

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
