초록
Crushing failure mainly occurs during collision events between ships or offshore objects, such as collisions between ships or between ships and bridges. To ensure safety against such collision events, the evaluation of the collision resistance is important and is normally conducted experimentally and/or numerically. In this study, the crushing assessment of a steel tube with and without transverse stiffeners for quasi-static compressive loading is numerically evaluated. The finite element series analyses show that the transverse stiffeners do not contribute to the ultimate crushing loads but affect the mean crushing capacities. As the slenderness ratio increases, the effect of the transverse stiffener reinforcement decreases. The finite element results were compared with previous experiment results.
Abstract
Crushing failure mainly occurs during collision events between ships or offshore objects, such as collisions between ships or between ships and bridges.

In this study, the crushing assessment of a steel tube with and without transverse stiffeners for quasi-static compressive loading is numerically evaluated. The finite element series analyses show that the transverse stiffeners do not contribute to the ultimate crushing loads but affect the mean crushing capacities. As the slenderness ratio increases, the effect of the transverse stiffener reinforcement decreases. The finite element results were compared with previous experiment results.
