[提要] 钢框架梁柱刚性连接节点是强震作用下的主要破坏位置,总结了梁端削弱式和加强式节点的应用特点,指出梁端加强式节点方案在实际应用时,由于加强梁端截面,在强柱弱梁抗震设计时,为满足规范相关计算要求,一般会造成柱截面加大或节点域腹板加厚。基于工程实践,提出相关的设计建议。

Abstract:In the action of strong earthquake,steel frame is mostly destroyed in the position of beamcolumn rigid joint.The appliance characteristics of the joint of weakening or strengthening the end of beam are summarized.It is pointed out that it must increase column section or thickness of panel zone of column web to satisfy the related design code and request of strengthening column and weakening beam in seismic concept design in the application of the mode of strengthening the end of beam.According to the engineering practice,some design sugge stions are put forward.
