The authors had presented previously the results of longitudinal strength calculation of a bulk carrier taking into consideration of "warping in bending". In above report, we pointed out that the effects of warping in bending could not be disregarded for condition of loading in which the rate of change of shearing force became large, such as in the alternatively loading condition. In this papar, at first, we extend the above mentioned method of analysis, which can only apply to the thin-walled uniform cross section beam, to the gradually variable cross section beam, in order to apply to the method of analysis for actual ship. Next, we examine the expanded method of analysis for its validty which is applied to the thin-walled variable cross section beam, by comparison between the numerical calculated results by 3D-FEM. and those results by this expanded method on the same numerical model of rectangular variable cross section beam. And then, we prove that this expanded method retain full validity for longitudinal strength of a hull girder taking into consideration of warping in bending.
