Guidelines of the shear stiffness of the corrugated steel plate are made in Europe and the USA. However, these guidelines are greatly different mutually. Then, this study shows the shear stiffness of the corrugated steel plate in detail, in order to aim at using as shear resistance panel. In this study, the energy method and F.E.M are carried out to clear the influence of corrugated shape, boundary condition and wave number on the shear stiffness of the corrugated steel plate. As a result, the diagram for evaluating the shear stiffness of the corrugated steel plate from these shape are shown.
