Abstract
Gived an account of methodology investigation to form-change and non-linear deformation of longspan covering of airfield hangar. Stated mathematical model for optimizing the shape and structure of the combined shell structure using the finite element method and the algorithm of the evolutionary problem is presented, which is based on controlling the shape of a discrete model of the surface of the coating using generalized design parameters. Received resultes of form-change at the example of proposed grate-span shell construction. Purpose of developing investigation is taking with numerical model form-change of shell construction with conditions assembling and final to be formed primary shell shape, as well as in defining to inside efforts in outward supporting contour, inside ring and thin-sheet shell for full calculationary loading.
