Sažetak
Hull girder ultimate strength is one of the most important criteria in design of a large thin-walled steel structure like ships, airplanes, etc. For large ship structures the hull girder ultimate strength is expressed as maximal internal vertical bending moment that hull structure can absorb before collapse. In this paper progressive hull girder collapse analysis has been performed for several different variants of large steel thin-walled boxes, taken from the literature as benchmark example, using non-liner (material and geometrically) finite element method (NLFEM). Results from the performed calculations were compared to the numerical results of other researchers and also with results of the conducted physical experiment, published in the literature. Influence of initial geometrical imperfection on the value of ultimate bending moment achieved with NLFEM has been investigated.
