Most of frame members in ship structure have fair depth compared with spans. Under increasing loads beyond the elastic limit of the structure, various failure patterns in the structural frames other than obtained ones by beam theory, such as flange buckling, web buckling, full plasticity, strut buckling, etc., will occur locally in these members before reaching failure load of whole structure. The failure modes and corresponding ultimate strengths vary depending on their modes of deformations. A method of the elastic plastic strength analysis of plane frame works considering the local failure modes introducing elastic plastic hinges is proposed and showed several examples of their applications. And it is shown that the failure modes and loads obtained by this method are practically agreed with the experimentally obtained ones.
