ABSTRACT
Although this topic is scarcely addressed by the contemporary researchers, some relatively current research work exists (Yao et al. 2004; Naar et al. 2008). This paper aims to propose ultimate bending capacity evaluation approach, which enables inclusion of the various distributed load effects arising when ships are subjected to the vertical flexural loads. Proposed progressive collapse analysis method is developed as an extensive modification of the incremental-iterative method prescribed by the IACS Common Structural Rules (IACS 2012a, b) (further in text: basic method), encoded and incorporated into the OCTOPUS (2012) computer program.
