In this paper, the buckling strength of bottom plating in ship structures is discussed theoretically and experimentally. Bottom plate is subjected to edge thrusts and lateral pressure at the same time. Since it deflects from the beginning, the critical point of buckling can not be determined with the aid of the usual buvkling theory. When the lateral pressure is small, buckling occurs at a certain value of the edge thrust. In case of large lateral pressure, on the other hand, considerable deflections appear due to lateral pressure alone and gradually with the increase of edge thrusts;then any critical state does not appear. The buckling tests were conducted with rectanguler plates of the aspect ratio 3 to 1 on an apparatus with a tank. The results of the experiments are in good accordance with the present elastic theory based on the principle of minimum potential enrgy and the optimization technique.
