【摘要】 利用ABAQUS有限元分析软件,对带有支撑的梁柱节点进行模拟计算,分析比较不同预埋件时梁柱节点应力分布与变形情况;对不同参数变化的节点组合体受力性能进行分析;同时,对节点是否带有支撑的计算结果进行对比,分析比较支撑对梁柱节点应力分布的影响.结果表明:预埋件构造方式的不同对梁柱节点应力分布、裂缝、变形影响比较显著,第四种方案较为合理;随着预埋件厚度和锚筋直径增加,支撑轴力均增大;通过在节点处设置支撑,有效地降低了节点的应力,使梁上产生了明显的塑性铰.更多还原

【Abstract】 Using finite element analysis software ABAQUS,the beam-column joint with support was computed simulatively,the stress distribution and deformation of the beam-column joint were analyzed and compared in the case with different embedded parts,and the kinetic performance of joint combination with different parameters was analyzed.Meanwhile,the calculation results of beam-column joint with or without support were compared and the influence of the support on the stress distribution in the beam-column joint was analyzed and compared.The result showed that the influence of various constructional manner of the embedded parts on the stress distribution,cracks,and deformation of the beam-column joint was comparatively obvious,and the fourth option was more reasonable;as the thickness of the embedded parts and diameter of anchor rib increased,the axial forces in the support would increase.Beam-column joint with support would effectively decrease the stress in the joint,making a plastic hinge on the beam.更多还原
