摘　　要： 宝安体育馆钢屋盖平面尺寸 140m× 140m ,支座内径 10 1 4m ,最大外悬挑 48 2 95m ,用钢量 6 8kg/m2 。屋盖中央节点构造设计为国内首次采用。非破坏试验的试验荷载为设计值的 1 5倍时 ,节点安全可靠。体育馆现已建成。介绍该体育馆钢屋盖的结构设计 ,供设计人员参考。 The plane dimension of Bao′an Gymnasium is 140m×140m,and its inner diameter of supports is 101.4m.The maximal dimension of outer cantilever is 48.295m with the steel consumption being 68kg/m 2.The constructional design of the central joint of the roof has been adopted for the first time in China.When the experimental load of the nondestructive test reaches 1.5 times of the designed value,the joint is safe and reliable.Now Bao′an Gymnasium has been completed.This paper gives a brief introduction to the structural design of the steel roof of the gymnasium, which may be a reference for designers.
