在理论计算和试验的基础上,应用ANSYS有限元分析软件,研究在相同的荷载和边界条件下,内环板的不同宽度对钢管混凝土柱节点性能的影响规律。结果表明,内环板的宽度对节点梁端的最大位移无明显影响,对节点的最大应力有显著影响;节点破坏时,梁首先破坏,加强环板是安全的,因此内加强环板焊接可以考虑不采用全熔透焊缝。
On the basis of theoretical calculation and experiment, the influence of different widths of inner ring plate on the joint performance of CFST columns under the same load and boundary conditions is studied by ANSYS finite element analysis software. The results show that the width of the inner ring plate has no significant effect on the maximum displacement of the beam end and has a significant effect on the maximum stress of the joint. When the node is damaged, the beam first destroys and the ring plate is strengthened, so the inner ring plate welding can be considered Do not use full penetration weld.
