ABSTRACT
The method developed for determining the upper and lower bounds of the critical load parameters in elastic ribbed shells is described. The critical parameters for cylindrical shells with three types of stiffening, namely, by cross ribs, by stringers and by rings only, are justified experimentally. It is shown that the lower bounds of the critical loads agree with the minimum experimental parameters much better than the upper bounds of the critical loads determined from the linear momentless theory.
