The calculation of load-bearing reinforced concrete structures was performed using the SCAD 21.1 program. Pile foundations were calculated in the program. As a result of the calculation, the linear forces in the walls and the forces in the columns, the shearing and bending forces in the lintels, the span and support moments in the floor slabs were determined. As a result of the calculation of the DCF, the reinforcement of all load-bearing elements was assigned. The execution of calculations of load-bearing structures is focused on the application of the finite element method in the form of the displacement method (FEM). The division of the plate elements of the building into finite elements is assigned taking into account that the internal forces determined by the calculation in the center of each finite element correspond to the actual work of the structure. In the design scheme, the connection nodes of foundations, columns and ceilings are assumed to be rigid. The calculation of floors is made for the total load, taking into account the own weight of the structure of the slab, floor, partitions, equipment, people, taking into account the appropriate overload factors for strength and crack resistance. As a result of the calculation of the DCF, the reinforcement of all load-bearing elements was assigned. The calculation is made taking into account the joint work of all building structures, foundations and the foundation of the building. To take into account the joint work of the building structures with the foundation at the level of the bottom of the piles, elastic links are introduced into the design scheme, simulating the elastic work of the soil and uneven settlement. 6 e. description and justification of technical solutions that provide the necessary strength, stability, spatial immutability of buildings and structures of the capital construction object as a whole, as well as their individual structural elements, assemblies, parts in the process of manufacturing, transportation, construction and operation of the capital construction object.
