A computer program, written for the IBM 7090 computer, is described which determines the internal forces, displacements, and reactions in a simply supported, multiple-cylindrical shell subjected to a set of known loads and boundary conditions. The structure analyzed may consist of up to 25 circular shell segments joined along their longi-tudinal edges. The program uses a direct stiffness solution in matrix form to analyze the multiple shell system and the formulation is based on the Donnell-Jenkins shell equation. Results obtained using the computer program are presented and used to discuss the effect of a number of varables in the design of multiple cylindrical shells.
