摘　　要：研究了带支撑节点板钢框架梁柱节点的抗弯性能.在ABAQUS有限元分析软件中采用C3D8I单元分别建立了6个由端板或双腹板角钢连接的钢框架梁柱节点模型,其中,2个不带支撑节点板,4个带支撑节点板.研究在正、负弯矩作用下支撑节点板对钢框架梁柱节点承载能力、转动刚度的影响,并分析了增设底角钢、端板外伸等措施对带支撑节点板钢框架梁柱节点抗弯性能的影响.分析结果表明,支撑节点板使钢框架梁柱刚度提高,具有了半刚性,明显提高了节点的抗弯性能,增设底角钢和端板外伸有助于提高带支撑节点板钢框架梁柱节点抗弯性能.To explore the flexural performance of steel frame beam-column connections with gusset plate,the models of 6steel frame beam-column joints,connected with double web angle or end plate were established by using the C3D8 I element in ABAQUS finite element software.There were two of the joints with gusset plate and four without gusset plate.Considering two conditions in which the joints were respectively under the action of positive and negative bending moment,the effects of gusset plate on the load bearing capacity and rotational stiffness of steel frame beam-column joints were studied.The influences of the measures,such as adding a seat angle and setting an one-side extended end-plate,on the flexural performance of steel frame beam-column connections with gusset plate were investigated.The results show that the gusset plate makes the steel frame beam-column joints semi-rigid,which significantly improves the flexural performance of the joints.Adding the seat angle and setting the one-side extended end-plate are helpful to enhance the flexural performance of steel frame beam-column connections with the gusset plate.
