It is important that ships are prevented from fatal failures such as the hull girder collapse under-severe sea conditions. On the other hand it, is also important, to know the reduction of the strength of a ship with lightening caused by the constant, demand for lighter ship hulls. Severe shear force acts in the side shell near the bow of the ship during slamming conditions. Thus it, becomes important to investigate not, only compressive behavior of the deck panels but, also shear collapse behavior of the side shell panels to determine the collapse behavior of the ship's hull girder. Simply supported and uniform shear load boundary conditions are suitable to examine the plate behaviour until the shear collapse load. But, strength evaluation considering the. Continuity between side shell panels is needed to analyze the load carrying capacity accurately during the post, shear collapse. In this paper it is intended to solve only one panel considering the inplane and rotational continuity between panels as the boundary condition instead of solving many panels to investigate the panel behavior of the post ultimate strength region, such as the load carrying capacity under shear.
