As a part of the study on the structural reliability analysis of marine plate structures, this study deals with the simplified collapse and reliability analysis using 8 node hexahedral element models. Firstly, marine plate structures are replaced with hexahedral element models having the equivalent strengths under combined inplane stresses and lateral pressure. Secondly, the behavior of failed elements is derived by applying the simplified and efficient methods using the linearized failure condition and a plastic node method based on the plastic potential theory. Finally, the validity of the analytical system is demonstrated by giving numerical examples on a double hull box girder with longitudinal stiffeners under several loading conditions.
