Stiffened shells of various forms are analysed. The exact formulation of the interaction of the shell and the discretely spaced stiffening beams allows to evaluate the influence of the individual parameters. The obtained exact solutions were compared with the approximate results based on the theory of anisotropic shells with smeared-out rigidities. The optimal values of the stiffening ribs are determined both for various shell forms and loading cases. The main emphasis is placed on cylindrical shells, but also conical and shallow shells are studied.
The four chapters are: general equations of stiffened shells; the case of the static loading; vibrations of stiffened shells and the stability of cylindrical shells.
The used mathematical tools are: classical simple or double series solutions and variational approaches. Numerical results illustrating the theory are always presented and also some comparisons with experimental data are given. The literature gives 461 references, about 400 in Russian.
