The longitudinal frame is the most fundamental and common structure in ship hull. However there are few papers that have investigated the typical features of the actual scantlings of the longitudinals. Especially as to the asymmetric sectional frame, it shows unexpectedly high torsional warping deformation and the resultant high stresses. The typical features in longitudinal frames in ship, when modeling to torsional warping beam, is that they are connected to adjoing frames. And another point is that their sectional deformation is easy to occur defying the premise of the thin thickness elastic beam theory. Therefore the authors have thought out a simplified model to consider these effects and compared the stresses thereby obtained with the result of FEM stress analysis.
