Abstract
Spatial structures are designed to change the architectural appearance of our cities, to contribute to the creation of expressive architectural complexes of industrial and cultural structures. Airports and train stations, congress halls and business centers, offices and banks, commodity exchanges, wholesale and retail warehouses, supermarkets and markets, exhibition pavilions, cinema and concert halls and sports complexes, as well as various engineering structures - this is far from complete a list of objects in the upcoming construction of which the use of spatial structures will be required. The rapid development and widespread use of thin-walled reinforced concrete spatial structures became possible thanks to significant advances in the theory of calculating shells and folds, the use of electronic computing technology, as well as the implementation of comprehensive and improved methods for the construction of large-span structures. In world practice, a clear trend is the use of spatial structures of various forms, giving expressive architectural samples and solving functional problems. it is important to calculate shells of shells sometimes indispensable in the construction of special structures. The analytical methods for calculating shells known in the literature become unacceptable for shells of complex shapes. The complexity of the shell shape may be due to the complexity of the outline of its middle surface and the complexity of the outline of its contour (boundary) lines. It can also be caused by the formation of the surface of the shells as a combination of several simple surfaces. The need to give the casings a special shape is dictated by various factors. The problems of studying the elastic equilibrium of shells are associated with certain mathematical and technical difficulties, since their stress-strain state is described by high-order equations with variable coefficients. One of the directions of modern structural mechanics is the introduction of new forms of thin-walled spatial structures into engineering practice. At the same time, the study of the geometry of these shapes, the development of methods for calculating shells of complex geometry is one of the main tasks of this direction. Shell f
