In the conventional limit analysis, it is supposed that the circumferential plastic hinge line is formed at the same position in a plate. However, there would be a contradiction in this assumption and it is necessary to re-examine the hypothesis used in the conventional limit analysis. Because, from our previous experiments, it has been confirmed that the plastic hinge line spreads gradually. The elastic analysis under the constrained support conditions both inner and outer peripherally, which bending moment and membrane force act at the same time, is described in this paper. Especially, as the preliminary step for considering the model of numerical analysis, the finite deformation analysis will be compared with an infinitesimal one, and we will investigate how those results influence the model of the plastic analysis.
