The development of engineering and design, the emergence of new materials (steel, concrete, aluminum, etc.) stimulated the emergence of new types of large-span structures. The structures became lighter, this made it possible to increase the size of the overlapping area. The use of large spans is due to the operational and architectural requirements in public buildings (markets, train stations, stadiums, concert and sports halls). In industrial buildings, large spans are subject to technological requirements. The space freed from supports, covered with a large-span structure, gives the building an emotional and plastic expressiveness. The use of large-span structures makes it possible to maximize the bearing qualities of the material and thereby obtain light and economical coatings. Reducing the mass of structures and structures is one of the main trends in construction. Less weight means less material, less material to be mined, processed, transported and installed.
