Deformation and Strength of a Horizontal Reservoir Having an Oval Cross Section

抄録

A reservoir supported horizontally and partially by saddles yields a very large deformation. Tolerable limits of the deformation may vary according to the working conditions of a reservoir. In the present paper, the authors tried to find the shape of a reservoir which does not yield too much deformation under partial support condition. Reservoirs having an oval cross section which is formed by three circular arcs are investigated. Stresses in a reservoir and its deformations are found as the solutions of the differential equations for cylindrical shells introduced by one of the present authors. Experimental study is made along with the theoretical analysis. The results show that there exists an optimum oval form which holds the deformation of a reservoir under desired level.
