摘要
本文介绍对上海市八万人体育场屋盖大悬挑空间结构进行的１／３５缩尺模型试验和大管径直接焊接节点足尺模型试验。试验表明，该结构空间工作性能显著，次应力影响不能忽略，并验证了计算方法的可靠性。本文中的Ｋ型节点足尺试验为大管径直接焊接节点计算提供了可靠依据。
The 1 : 35 scale model of the roof structure of a 80000-seat stadium in Shanghai, made up of radial long cantilevered main trusses and annular secondary trusses, as well as the full scale large size specimens of unstiffened steel tubular K -joints have been tested . The results of the overall structure test indicate that the roof system has strong space working behavior, and it verifies the reliability of the calculation method . The static loading tests of the full scale K-joints make perfect the theory of unstiffened steel tubular joints with large diameter members .
