This paper presents further development of coupled beam (CB) approach introduced by Naar et al. (2004) for the analysis of multi-deck ship structures. The strength assessment based on CB-method allows time-efficient analysis compared to the finite element (FE) approach. The CB-method is based on the assumption that each deck in the superstructure and also the main hull can be considered as a thin-walled beam with bending and axial stiffness. The cross-section can be divided into beams which are coupled to adjacent beams with distributed springs accounting for vertical and shear stiffness. The shear effect in the side and deck structures is included with options for large openings. In (Naar et al., 2004) the CB theory is based on continuous coordinate functions. Here, piecewise continuous approach is implemented in order to describe the local structural discontinuities more accurately. Three simplified plated structures were analyzed in order to validate the CB-method against the three-dimensional FE-method.
