To investigate ship structural responses in waves, the authors conducted experiments in the ship model basin on hull girder strength in regular waves. The model used for these experiments was made of metal (brass) plate and its scale was about 1/57 of a 30000 DWT cargo ship. The characteristics of stresses induced on the longitudinal strength members in waves were clarified. Also, the experimental results were compared with the calculated ones obtained by using the so-called total system of computer program for hull girder strength analysis. This system, developed by IHI, consists of the following programs systematically; response analysis on ship motion in waves by Ordinary Strip Method, structural analysis of hull girders based upon the general bending and torsion theory, and statistical analysis. And the system has been modified with much effort through various experiments. The calculated results were in agreement with the experimental ones. It was confirmed that the numerical calculation technique according to this program system has a practically warrantable accuracy. (Wassmann)
