六安体育中心体育场钢屋盖结构设计

Structural Design of Steel Roof of Lu′an Sports Center Stadium

六安体育中心体育场下部主体为现浇钢筋混凝土框架结构,看台钢屋盖采用空间悬挑管桁架,主桁架最大悬挑31 m。文章阐述了钢屋盖结构体系构成分析,对不同部位构件采取差异化的控制标准,对尾部钢拉杆进行张拉过程模拟分析,并对桁架关键节点进行了有限元分析。

The main body of the lower part of the stadium of Lu′an sports center is a cast-in-place reinforced concrete frame structure.The steel roof of the stand adopts spatial cantilever pipe truss,and the maximum cantilever of the main truss is 31m.In this paper,the composition analysis of steel roof structure system is described.Different control standards are adopted for different parts of components.The tension process of tail steel tie rod is simulated and analyzed,and the key joints of truss are analyzed by finite element method.
