摘要：为研究部分包裹混凝土组合柱（PEC）与钢梁节点的抗震性能，进行了6个不同构造的PEC柱钢梁外伸式端板连接节点试件的低周往复荷载试验，与普通H型钢柱外伸端板连接节点试验结果进行了对比，分析了填充混凝土、端板厚度及是否添加背垫板和腹板加劲板对节点滞回性能、延性和耗能能力的影响。试验及对比结果表明：填充了混凝土的部分包裹混凝土组合柱梁柱端板连接较之普通H型钢柱外伸端板连接节点可节省用钢量，具有良好的滞回性能和延性。加设背垫板可改善宽肢薄腹组合体连接的抗震性能。

Abstract:Inorder to study the seismic performance of the connections between partiallyencased concrete composite columns (PEC columns) and steel beams, low cyclicload tests were designed for 6 different structural specimens of the extendedend plate connections between PEC columns and steel beams. Comparing with the connectionsbetween H-type steel columns and beams about filling with concrete, he effectof the thickness of the end plate and the whether adding back plates and webstiffeners on hysteretic behavior, ductility and capacity of energy dissipationwas analyzed. The results show that the end plate connections of PEC columnscan not only save the amount of steel, but also have good hysteretic behaviorand ductility. Besides, the back plates can improve the seismic performance ofthe wide limb and thin web combination connections.
