The article is dedicated to the construction of the "bending moment-curvature" diagrams for rectangular cross-sections of reinforced concrete bending elements. Assumptions and equilibrium equations used in the construction of diagrams are given in the article. The algorithm for the construction of the "bending moment-curvature" diagram is shown. Diagrams constructed by the proposed algorithm are compared with experimental data and with the results obtained by the methods proposed by other
