Practical application limits and scope related to confinement reinforcement of loadbearing concrete structures are continuously expanding. However, strength and deformability of compressed and bending elements with confinement reinforcement are calculated based on empirical equations. The purpose of this article is to propose new equations for determining strength and ultimate shortening deformation of volume-compressed concrete that would reflect the key mechanisms of their force resistance and ensure higher accuracy of calculations when compared to the currently used ones. The comparison with previously reported empirical data demonstrated that such equations were obtained. An important advantage of these equations is that they take account of all the main factors influencing mechanical properties of volume-compressed concrete and are universally applicable.
