The areas of application of concrete and reinforcement of higher grades for strength in structural elements of a monolithic reinforced concrete frame are considered. Analytic dependencies, criteria and boundary conditions are proposed that numerically describe the relationship between increasing the strength of concrete and reducing the consumption of reinforcing steel for bent and compressed-bent elements. Calculation-analytical models of the deformation state of overlaps of a monolithic reinforced concrete multi-storey frame have been developed on the basis of multifactor numerical studies carried out for various values of the thicknesses of ceilings, spans, operating loads, classes of concrete and reinforcement. Calculated parameters of slabs are determined, which determine their bearing capacity. On the basis of computer technology, the optimum section of a reinforced concrete element is modeled according to the criterion of reducing the material consumption and rational combination of classes of concrete and reinforcement.
