摘　　要：为了探讨梁柱端板连接的滞回性能 ,进行了 8个节点试件的循环加载试验 ,其中涉及到加劲肋作用的有 5个 ,试验中柱端施加了轴向压力。试验结果表明 :加劲肋不但可以提高节点刚度和承载力 ,改善滞回性能 ,而且可以延缓梁翼缘与端板间焊缝的开裂 ,减小撬力 ;端板连接具有良好的延性和耗能能力 ,节点的转角都超过了 0 .0 3rad。In order to study the hysteretic behavior of extended end plate connections, 8 connections with four tension bolts are tested to failure under cyclic loading. Among them, 5 specimens are used to analyze rib stiffeners′ actions. Constant axial compression force is applied on the end of 7 columns during the tests. It is showed that stiffeners can not only improve bearing capacity and stiffness of connection, but also delay the fracture of weld between beam flange and end plate. End plate connections behave well in ductility and energy dissipation, and the rotation of most connections exceeds 0.03 radians. Finally, suggestions for design and construction are put forward basd on the experiment results.
