The paper presents a method to estimate the displacement of the neutral axis of a damaged ship subjected to bending moment. The method uses the load-end shortening relationship obtained from previous numerical double bottom residual strength calculations establishing force equilibrium over the whole transverse section of the ship. The set of estimated neutral axes allows the definition of a new load condition to induce a higher bending moment on the double bottom structure. The new residual strength is compared with previous numerical calculations for the intact and minor damaged double bottom in which the bending moment was induced considering the neutral axis fixed during the entire simulation. The comparison showed a reduction in the capacity of the double bottom structure when the bending moment is induced by the new load condition.
