increase factor of the reinforcement DIF y and the relative strength of the reinforced concrete element with the deformation rate remains close to linear. The developed methodology can be recommended for the operational assessment of the stress-strain state of flexural reinforced concrete elements in normal sections under the action of dynamic loads of different intensities, since, unlike all others, it can be implemented even without the use of special software packages. In the future, this methodology will be improved for flexural elements with double reinforcement and eccentrically compressed elements, and extended to predict deflections and normal cracks under dynamic loads.
