Abstract :A semi-analytical model for ultimate strength capacity assessment of stiffened plates has been developed based on ANSYS non-linear elasto-plastic buckling analyses of a wide range of typical ship panel geometries. The primary aim of the present study is to investigate the ultimate strength interaction relationship of a stiffened plate subject to combine loads with imperfections in the form of geometric deflections and welding induced residual stresses. The accuracy of the interaction relationship is confirmed by use of inelastic finite element calculations. Comparison is performed with existing ship rules used by Classification Societies as well. The results and insights derived from the present work are summarized in great detail
