Abstract
The enhancement of the reinforced concrete plain structures design methods on the basis of the deformation theory of the plasticity of reinforced concrete with cracks by N.I. Karpenko is considered. The deformation model of reinforced concrete with cracks taking into account the deformation diagrams of concrete and reinforcement is used for numerical analysis of a deep beam made of high-strength concrete of class B100. The analysis makes it possible to conclude that taking into account the actual properties of materials significantly improves the accuracy of computer modeling. The strength of concrete is the decisive factor determining the mechanism of structural failure and the efficiency of using reinforcement. At the design stage, the most reliable and accurate tool for assessing the operational fitness of planar reinforced concrete structures is computer modeling based on a nonlinear deformation model, taking into account the actual strength and deformation properties of concrete and reinforcement
