IACS incremental-iterative method in progressive collapse analysis of various hull girder structures

Intended purpose of the paper is to compare results obtained by the different existing ultimate bending capacity assessment methods for different hull girder structures, with particular emphasis on the results obtained by subgroup of methods comprised of the different incremental-iterative progressive collapse analysis methods based on the Smith’s approach. Within this subgroup of methods, additional consideration is given to results obtained by different implementations of the same method prescribed by the International Association of Classification Societies (IACS) Common Structural Rules (CSR), since this method is incorporated into OCTOPUS computer program, developed at the Faculty of Mechanical Engineering and Naval Architecture (University of Zagreb). Various characteristics and capabilities of the implemented IACS CSR incremental-iterative progressive collapse analysis method are considered on the example of the hull girder structure of the chemical tanker, along with the comparison of results obtained by the NLFEA method.
