A method of three dimensional elastic-plastic analysis of frame structures consisted of main transverse and longitudinal members like web frames, girders, side shells and longitudinal bulkheads etc. of oil tanker or ore carrier etc. which are subjected to transverse extreme loads is presented. The purpose of this paper is to predict development of plastic strain, generation of plastic hinge, local or single span buckling in the framed members and collapse load of the whole frame structure based on elastic-plastic analysis of transverse frame rings which are supported by longitudinal members like longitudinal girders, longitudinal bulkheads or side shells etc. elastically, providing that those longitudinal members are assumed to be supported by transverse bulkheads. This theory is applied to analyze the experiments for models of the plane frame structure conducted by authors and the three dimensional structural models of ore carriers conducted by T. Suhara et al. Good agreement of the results between each of them is shown.
