ABSTRACT
Optimization of the load-bearing system of a building implies a wide variety of problem settings, determined by the type of structure (column, floor, etc.), material properties, type of load (statics, dynamics, thermal effects) and the selected design scheme. The LIRA-SAPR software package was used to calculate 32 design options. Based on the results confirming the bearing capacity of the building, as well as individual building structures, the stress-strain state of the bearing system and the reinforcement of reinforced concrete elements were determined. The objective function was formulated according to the criterion of the minimum cost of materials for the bearing structure, where the expected costs are summarized in three main groups: costs of the designed structure, operating costs, costs to eliminate the consequences caused by potential emergency situations. The boundary conditions for the objective function: geometric (location, number of pylons in the space-planning; variable pylon parameter; slab thickness value) and strength (options for classes of concrete and reinforcement for pylons and floor slabs).
