Abstract
An application of ISUM to analyse collapse behaviour of large ship structural modules is developed. The system analysis of 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 Timoshenko-beam elements for the girder web plates. Fundamental collapse modes and localized failures in double-bottom structure under pressure loads are obtained in 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.
