Zusammenfassung:	This paper is concerned with the variational formulation of the optimum design of plastic cylindrical shells with stepwise varying thickness and stiffeners at joints (sections between two contiguous elements). The optimality criterion is attained by using a variational formulation. The saving achieved by using stiffeners is shown by means of an example.
