As regards the free vibration of rectangular plate, stiffened by beams, with elastically built-in edges, we can refer strain energy method by Mr. Okuda and Arima, and slope-deflexion method by Mr. Suhara. The author, in this paper, presents theoretical treatise in which he expressed the reacting forces and moments of the stiffeners or boundaries by the impulsive function of o-th or 1st oder, and obtained the characteristic solution and the value of homogeneous partial differential equation of the rectangular plate, under the conditions that the two opposite edges of the plate are simply supported and the other two oppositesides elastically built-in, which are parallel with the stiffeners. And he showed some numerical examples of them. Foot Notes : 1) Katumi Okuda and Takasi Arima : "Strength and Frequency of Natural Vibration of Rectangular Plate with Longitudinal Stiffeners", Jour.
