The structural behavior of box-girders under pure bending moment is analyzed and discussed on the basis of the results of experiments performed by the author. The box girders are geometrically similar but made of different materials and having different stiffener’s geometries. The influence of the main parameters that influence the ultimate strength of box-girders under pure bending moment is analyzed and discussed. It was found that the plate and column’s slenderness have great impact on the ultimate bending moment of box-girders. Practical design formulas are derived and presented, allowing for a fast evaluation of the performance of the boxes under pure bending. The achievements may be extrapolated to the analysis of the hull girder of ship and used as a basis for the structural codes of ship design
