| 摘 要： | 利用有限元程序ABAQUS计算了海洋平台内部设置加强环的T型相贯节点在不同温度下的极限承载力，探讨了T型相贯节点在不同温度下的极限承载力和变形性能，考虑了在主、支管相交区域内设置不同数量、不同宽度和厚度的加强环对节点在不同温度下极限承栽力的影响，并和不设加强环的T型相贯节点的极限承载力进行了比较。

| Abstract: | Using finite element program-ABAQUS, the load capacity of offshore T-joints with interior reinforced ring at elevated temperatures was calculated. The load capacity influ ence of the different number, width and thickness about reinforced ring at different tempera tures was considered, and comparison of the load capacity of the tubular T-joints with no rein forced ring was made. |
