Influence of Warping due to Vertical Shear Force on Ultimate Hull Girder Strength(2nd Report)

Abstract

The ultimate longitudinal strength of a hull girder is, in usual, analysed for the cross-section where the maximum longitudinal bending moment occurs. In this case, the effect of shear stress is not considered. There may exist,however, a cross-section having a similar magnitude of bending moment together with large shear force for example in case of an alternate loading condition of bulk carriers. The progressive collapse analysis by the Smith's method was carried out to estimate the ultimate longitudinal strength of a hull girder cross-section taking the effect of shear force into consideration.
