Abstract
An application of ISUM to analyse the collapse behaviour of large ship structural modules is developed. The system analysis of a double-bottom structure as well as isolated floor and girder models is achieved with models consisting of large plate elements and beam-column elements for the inner and outer bottom plating and of Timoshenko beam elements for the girder web plates. Fundamental collapse modes and localized failures in a double-bottom structure under pressure loads are obtained in a very short time compared to FEM. Local collapse of rectangular plate panels under transverse thrust rapidly spreads from the central area of the double-bottom towards the sides and stool supports, but the structure exhibits considerable reserve strength in the overall bending.
