The buckling strength of stiffened plates under the compressive loads acting toward the lengthwise direction of stiffeners was studied. First, the elastic buckling of stiffened plates was analyzed assuming that every other stiffener deforms quite similar. As a result of this study, it was clarified that there are two cases, the case where the buckling is caused by bending and that where the buckling is caused by torsion. Next, the elastic buckling of stiffened plates with finite stiffeners was analyzed, and a result was acquired that, as the number of stiffeners increases, the buckling load closes with the smallest buckling load obtained by assuming every other stiffener deforms quite similar. The experiments were carried out using two kinds of stiffened plates, and the results of analysis were confirmed.
