[提要] 介绍了钢结构加腋型梁柱焊接节点的结构、形状、主要参数与重要部件，并对其抗震性能进行了探
讨。加腋型节点的塑性铰在远离柱翼缘面的梁上形成。与一般的梁柱节点相比，其韧性行为稳定，强度得到提高。与目前流行的削弱梁截面的改进型节点比较，加腋型梁柱焊接节点具有更大的塑性转角与更强的抗震性能。
[关键词] 钢结构 加腋 梁柱节点 塑性铰 抗震性能The configuration,shape,main parameters and important components of beam-column welded connection with welded haunch in steel moment-frame are presented,and its aseismic performance is discussed. Studies indicate that the connection with welded haunch shifts plastic hinge away from the face of the column. Compared with normal connection, this connection has a steady performance of the ductility,its strength is also improved, and achieves larger plastic rotation than that with RBS( Reduced Beam Section), therefore, has better aseismic performance.
