Abstract
In 1938 standards were adopted in which the method of limiting equilibrium, developed by prof. А.А. Gvozdev and V.I. Murashev, was recommended for the calculation of reinforced concrete structures. From the very beginning, the proposed method caused a sharp discussion in the scientific community, since it contained number of contradictions. Most of the contradictions in the theory of A.A. Gvozdev became part of modern Russian standards. Until now the method of limiting equilibrium remains the main method for calculating reinforced concrete structures for strength. In recent years, a discussion has been developed on the transition to the deformation model of reinforced concrete resistance used by the European codes. In view of this, the updated version of domestic regulations allows the calculation of reinforced concrete structures using a nonlinear deformation model. However, there is a limited number of studies confirming the consistency of the proposed deformation model. In this regard we performed a series of calculations of rigidity of hinged supported on the basis of the theoretical and deformation models of the Russian standards. The calculation was carried out by the finite element method using the model of nonlinear deformation of concrete.
