Abstract
Reinforced concrete thin-walled large-girder shells of complex configuration ‒ remarkable and efficient structures that are used to create accent in the most important places of society. One of the main advantages of reinforced concrete thin-walled large-span shells is that the loss of stability of individual structural elements does not lead to immediate destruction. When building monolithic structures, it is easier to solve problems associated with joints and their sealing. The absence of seams in buildings prevents the formation of cracks, increasing the structural strength and durability in operation. This, in turn, favorably effects on the sound-, heat- and waterproofing of the structure. Efficiency of the erection of such buildings is ensured by: low cost of construction; high carrying capacity; safety in operation, even if the part of the structure is damaged; small own weight, which does not have a great influence on the geotechnical environment; the possibility of erection in hard-to-reach areas. Modern technologies allow erect buildings and structures quickly, of various configurations, regardless of the elements type. The main reason behind the massive construction of shells in Ukraine is the disproportion between the optimality of thin-walled structures and the disadvantages of their construction methods, which are based largely on the experience of the flat systems construction. A detailed analysis of the formwork systems made it possible to select the formwork for buildings and structures of complex configuration.
