摘　　要：衡阳体育馆为设计施工一体工程,结构最大外圆直径96m,外壳采用大跨钢管桁架结构,沿径向均匀设置36榀平面钢管桁架,桁架汇交于直径为22m的压环桁架,设置了面外桁架及交叉支撑,提高了屋盖的整体刚度。设计了柱顶球形滑移支座,对关键节点进行了有限元分析,保证其安全可靠。The construction project of Hengyang stadium is the one combined with the task of designing. The largest diameter of the structure is 96 m. The shell adopts the long-span steel truss structure.36 plane steel trusses are evenly set along the radial direction. The trusses converge at the pressure ring truss with the diameter of 22 m. The normal truss and cross-bracing are designed to improve the overall rigidity of the roof. The spherical slippage bearing are designed on the top of the columns. And the key nodes are analyzed with the finite element analysis to ensure the security and the reliability of the structure.
