摘要
利用有限元软件ABAQUS计算海洋平台T型相贯节点在火灾作用下的极限承载力,并对T型相贯节点进行火灾作用下的抗火性能及节点在降温段的力学性能分析,得出在不同火灾温度下节点的极限承载力。同时对计算结果进行了分析比较,通过参数分析,得到了T型相贯节点在火灾作用下节点极限承载力的变化规律。
The load beating capacity for tubular T-joints of offshore platform under fire is calculated by using the finite element software ABAQUS. The analysis of mechanical performance for T-joints in fire and during cooling is conducted. The load bearing capacities under different temperatures are obtained. At the same time, comparison of analytical results is made. According to the results of parametric analysis, conclusion of load bearing capacity for tubular T-joint at elevated temperatures is obtained.
