The stress mechanism and bearing capacity calculation method are not clear.The full-scale joint loading tests and finite element analysis were carried out in order to verify the safety under the design load.The change of strain stress and displacement in the various part of the joint were obtained from the tests. Key words:steel structures;spherical plain bearing;static experiment;strain;finite element analysis 1试验背景 15000kN.试验节点构造如图2所示. 江苏大剧院钢结构工程跨度大，钢柱形状不规 则，为释放端部弯矩，柱端与支座选用铰接连接. 为实现空间上的铰接，本工程在钢柱端部采...
