| 摘 要： | 针对屈服线模型计算管结构节点的极限承载力偏于保守的情况，考虑焊缝尺寸的影响，修正了T型相贯节点极限承载力计算公式，并借助有限元软件进行对比。结果表明，CIDECT公式计算结果偏于保守，修正公式计算结果与有限元计算结果吻合较好，修正公式合理。

| Abstract: | Aimed at an alternative to the yield line model more likely to give a conservative cal- culation of ultimate bearing capacity of pipe structure joints, this paper discusses the modification of the calculation formula of ultimate capacity of T-joints, as dictated by the consideration of the influence of weld dimension, and the use of the finite element software for comparison. The results show that CIDECT formula tends to give a more conservative calculation while FEM gives the cal- culated values closer to the values derived from the modified formula, and the modified formula proves reasonable. |
