Study on mechanical performance of tubular T-joints of offshore platform under fire

The load bearing 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.
