    Abstract: </B> The and discusses the stress-strain state of reinforced concrete product at the action of concentrated bending load in the case of this load approximation to the supporting beam power. The study also provides the analysis of stress and displacement for the cases of prestressed reinforcement and the reinforcement without prestressing by applying a tensile load to a reinforced concrete beam.
