ABSTRACT
The analysis of ultimate torsional strength is an important part of structural analysis for a ship hull with large deck openings such as container ships and large bulk carriers. However, there are not many studies available on the ultimate strength of ship hulls under torsion. Nowadays, ship structural design is mainly based on the first yield of hull structures, with buckling checks for structural components and ultimate strength under vertical bending moment. For ship hulls with large deck openings, especially for container ships, the ultimate torsional strength is important.
