Abstract : The application of the Ritz energy procedure and of the method of finite differences to the analysis of cylindrical shell roofs that are simply supported along the curved edges is presented. The condition of support along the longitudinal or straight edges is considered to be arbitrary. The shell is assumed to be of uniform thickness, and the material of the shell is assumed to be elastic. There appears to be no critical study made of the application of these methods to the analysis of shell problems. Brief comments on a few known references on this topic are made. The principal objectives of this study were: (a) To provide information which would facilitate the application of these methods in the solution of specific problems, and (b) With the aid of numerical solutions, to study the degree of accuracy that can be achieved by each of these methods when a relatively small number of approximating functions or mesh points is used.
