摘　　要：为了研究不同形状参数下梁端翼缘加强板对梁端翼缘扩大型梁柱节点的影响,分析了不同形状的梁端扩大翼缘形状最优方案.基于梁端强度相同的准则,改变其翼缘加强板的形状,设计了三种形状的梁端翼缘扩大型梁柱节点.利用有限元分析软件ABAQUS建立了不同形状参数下的有限元分析模型,研究在静载作用下节点的力学特征,对比分析不同材料参数的扩翼对梁端翼缘扩大型节点性能的影响程度.结果表明,不同扩翼形状对节点承载力水平影响并不显著,而对节点处应力分布影响较大;扩翼强度对节点的受力性能影响不大.In order to study the influence of beam flange stiffening plate with different shape parameters on the beam-column joint with widened beam flange, the optimal shape scheme for the beam widened flange with different shapes was analyzed. Based on the same beam strength criteria and through changing the shape of flange stiffening plate, the beam-column joint with widened beam flange with three shapes was designed. With the finite element analysis software ABAQUS, the finite element analysis model with different shape parameters was established. In addition, the mechanical properties of the joint under the action of static load were investigated, and the effect of flange with different material parameters on the properties of beam-column joint with widened beam flange was compared and analyzed. The results show that the different shapes of widened flange have no obvious influence on the bearing capacity level of the joint, but possess a great influence on the stress distribution at the joint. Furthermore, the strength of widened flange has a little influence on the mechanical properties of the joint.
