    Abstract. This article continues the author's series of articles on such an important experimental characteristic of reinforced concrete as the distance between cracks in centrally tensioned reinforced concrete elements and requires joint consideration. The collaboration principle for reinforcement of a periodic profile and tensioned concrete is formulated, taking into account the formation and development of primary and secondary cracks using the example of a reinforced concrete element subjected to axial tension. The proposed principle complements the previously formulated calculation prerequisites and assumptions for constructing the mechanics of reinforced concrete beams with normal cracks. The impossibility of zeroing or sharply reducing the tensile stresses in concrete after the formation of primary cracks is substantiated. Based on the research done and the analysis of the results, the nature of the primary and secondary cracks is described. The parameters characterizing the process of crack formation and opening are considered in detail. Important refinements have been obtained for the preparation and conduct of experiments on centrally tensioned reinforced concrete prisms.
    Keywords: tensioned reinforced concrete elements, primary and secondary cracks, the distance between cracks, the collaboration principle of reinforcement and concrete, axial tension
