If a ship strands it is important to estimate the acting forces and moments in respect to its ultimate hull girder strength. The influence of the shear force in combination with the bending moment needs to be taken into account. Therefore a procedure to calculate the moment-shear force interaction curve of a ship's cross section is introduced. Three specimens of an experiment (carried out by Reckling et al.) are recalculated with the FE method to validate the procedure. In the experiment longitudinal stiffened girders are loaded with pure bending. After the FE results are satisfactory equal to those of the experiment and the computing time is optimised, the shear force is additionally introduced by different load cases. Enough nodes for the moment-shear force interaction curve are found. Three normalised curves are presented-one for each of the three specimens. Various cross sections and lengths of the specimen result in different curves.
