The river-sea-going ship is often designed to be wide and flat due to the limitation of channel depth. Long and wide hatch opening is usually required in order to improve the efficiency of loading and unloading. There are enormous challenges on structural strength for such river-seagoing ship. In this paper, model test and nonlinear finite element analyses are combined together to research its progressive collapse behaviour under combined vertical bending and torsional moments. Test model is fundamental designed in accordance with distorted similarity theory in which plate thickness is considered as an independent dimension. Then, the similarity of slenderness ratio which is principal parameters affecting the ultimate strength of plating and stiffened plate subjected to compressive load is considered to determine the spacing and size of the stiffener. Finally, the ultimate strength of actual ship is deduced through that of test model and compared with that obtained by nonlinear finite element analysis.
