摘要

This paper presents the results of an experimental study to evaluate theeffect of torsional moment on the ultimate strength of container ships inlongitudinal bending. The progressive collapse tests are conductedusing 1/13-scale three-hold models referring to a Post-Panamaxcontainer ship. The models are fixed to the rigid wall at the aft end(cantilever beam) and a couple of loads are applied to the fore end so asto generate both torsional and vertical bending moments. Severalloading conditions which vary the ratio of torsional and bendingmoments are adopted for the progressive collapse tests and thenonlinear finite element analyses using LS-DYNA. From the results ofcollapse tests and numerical simulations, the progressive collapsebehavior including the warping-strain distribution and the ultimatestrength interaction relationship is examined.
