    Abstract. A brief review and comparison of classical and modern methods for calculating sections with normal cracks used at various stages of the stress-strain state is carried out. The list of stages of the stress-strain state is adjusted taking into account the additional stage - the formation and opening of diagonal cracks, on the basis of which the content of the failure stage of bending reinforced concrete elements is specified. The second stage of the stress-strain state of reinforced concrete beams during bending (the formation and opening of normal cracks) is considered in detail, taking into account the development of plastic deformations and creep in compressed concrete to create the prerequisites for the development of new mechanics of reinforced concrete beams with normal cracks. The following article will propose a universal calculation method that can eliminate existing shortcomings and combine the advantages of all known calculation methods - by allowable stresses and ultimate forces, the diagram method and the limit equilibrium method.
    Keywords: reinforced concrete beam, stress-strain state, compressed concrete zone, deflections of the beam, internal deformations in compressed concrete
