Failure of a ship hull girder is a very important failure mode, which is normally catastrophic and has severe consequences. It is of great importance to predict accurately the ultimate strength of a hull girder so that an adequate but not excessive safety margin for this failure can be ensured in the ship design. This study proposes a method for reliability-based analysis of the ultimate strength of a hull girder. The reliability method is interactively integrated with progressive collapse analysis so that the uncertainties in individual random variables relating to the prediction of the ultimate strength of a hull girder can be accurately considered in reliability analysis and that sensitivity factors of these random variables can be probabilistically evaluated. The ultimate strength will be evaluated using a progressive collapse analysis methodology with the appropriate individual element stress-strain curves derived interactively. The method is applied to two example structures and the sensitivities of the reliability to the random variables are presented.
