Research Abstract

In order to establish a total system to assess ultimate longitudinal strength of ship's hull girder under combined bending, torsion and shear, (1) efficient and accurate method of progressive collapse analysis of ship's hull girder under combined loads, (2) method of analysis of extreme wave loads on ships in rough seas, and (3) method of structural safety assessment of ship's hull girder based on structural reliability analysis were developed. Collapse tests of 1/13-scale container ship models under combined bending and torsion were carried out and their progressive collapse behavior and ultimate strength interaction relatioship were investigated.
