带端板加劲肋的外伸端板连接的梁柱节点试验

为了讨论加劲肋对连接性能的影响,对带端板加劲肋的外伸端板连接的梁柱节点进行了循环荷载作用下试验研究.分析了端板、端板加劲肋、梁柱翼缘和腹板在荷载作用下的应力情况,确定了这种连接的受力性能及破坏模式,分析此类连接的滞回曲线、连接初始刚度、承载能力和延性特征.试验结果表明,加劲肋是提高节点性能的一项有效措施.

Test on extended end-plate with end-plate stiffer beam-tocolumn connection

To discuss the effect of stiffer on the capability of the connection,the research on extended end-plate connection with end-plate stiffer under cyclic load was performed by test.Analyzing the stresses on the end-plate,stiffer,beam flange and web,column flange and web,the behavior and failure mode of the semirigid connection were determined,the hysteretic curve,the initial stiffness,the bearing capacity and ductility were analyzed.Test results indicate that the stiffer is an effective measure improving the bearing capability of the connections.
