[提要] 鋼框架梁柱剛性連接節(jié)點是強震作用下的主要破壞位置,總結了梁端削弱式和加強式節(jié)點的應用特點,指出梁端加強式節(jié)點方案在實際應用時,由于加強梁端截面,在強柱弱梁抗震設計時,為滿足規(guī)范相關計算要求,一般會造成柱截面加大或節(jié)點域腹板加厚。基于工程實踐,提出相關的設計建議。

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.
