Progressive collapsemethod is used to calculate ship ultimate hull girder strength and the combination of surface response method and traditional method is utilized to analyse reliability.
With the help of plastic hinge theory and collapse theory, the formulas for calculating strength failure load and the method for computing collapse load were established respectively.
