Abstract: | We discuss problems of the application of various reliability theories in models of optimal design of structures. Using the example of the problem of optimizing (with respect to the minimal mass criterion) the parameters of an inclined spherical shell reinforced by a network of ribs and subject to a random load stated as a nonlinear programming problem we give a comparative analysis of the optimal designs obtained using the theory of Bolotin and the theory of Kapur-Lamberson.
