Calculation methodology of reinforced concrete elements based on the calculated resistance of reinforced concrete is presented. The basic depending which allows setting the strength of bending sections and elements is obtained. The reliability of the dependencies is experimentally confirmed. There are calculation examples of bending elements by the developed methodology. According to the given method, tables have been developed, which depending on the accepted parameters allow determining the resistance of the concrete, the stresses in the reinforced concrete and reinforcement, and the total relative deformation of the cross section. Using the calculated resistances of reinforced concrete allowed to reduce the calculation of reinforced concrete elements according to the nonlinear deformation model to the application of the formulas of the classical resistance of materials and to significantly simplifies the process of their calculation.
