Borders and volumes of practical application of shear reinforcement of bearing reinforced concrete structures are constantly expanding. In this case, the calculation of strength and deformability of compressed and bending elements with shear reinforcement is performed on the basis of empirical dependences. In this paper, new dependences for determining the strength and ultimate deformation of the shortening of volumetric compressed concrete are proposed, which can reflect the basic regularities of their force resistance and provide better accuracy of calculations compared to those currently used. Comparison with the previously published experimental data showed that such dependences were obtained. An important advantage of these dependencies is that they take into account all the main factors affecting the mechanical properties of the volumetric compressed concrete and are universal.
