Abstract: 
The basic methods for calculating thinwalled rocket-space shell structures under local loading and contact interactions are presented. We studied effects of the local loading on supporting rigidity ribs (frames, stringers), contact interactions of shell structures with supports of various types, and local shape imperfections. We analysed the action of these factors on the stress-and-strained state, the local stability, and the carrying capacity of the rocket-space structures. The effect of material plastic deformations was estimated. The results of numerical analysis and some experimental data are given.
Keywords: carrying capacity, local stability, rocket-space structures, stress-and-strained state
