In this paper, we developed a new automatic calculation system in addition to new concepts, which was extended from the conventional automatic calculation system (ref. 3) where shear flow on the cross-section of thin-walled uniform beam is statically deteminated. Specifically speaking, for the thin-walled variable cross-section beam with multi-cell i.e. shear flow on the cross-section is statically indeteminated, we developed the new system which can calculate for the analysis, applying the new longituginal strength of a hull girder taking into consideration of "warping in bending" (ref. 4), automatically with the minimum input data. This new system can process the figures on the results of calculation by interactive computer programs. Next, we applied this new system to two kinds of double hull ship and confirmed that the new system was operated properly. Total working hours of the new system was very short in comparison with those of the conventional system. And then, taking account of the effects of warping in bending, the new longituginal strength theory of a hull girder is considered to have reached the stage for practical application.
