Abstract: This article provides suggestions for improving the method for analysis of the parameters of the stress-strain state of bent reinforced concrete elements, strengthened in the tension zone, taking into account the effects of concrete creep under a long-term load. The general non-linear deformation model for structural analysis of reinforced concrete elements under the combined action of bending moments and longitudinal forces is taken as a basis, using a mathematical description of the deformation diagrams of concrete and reinforcement. The proposed model makes it possible to take into account the effects of changes in deformations in concrete under the action of a long-term load. Experimental verification showed a satisfactory convergence of the results of the analysis by the proposed method with the experimental data.
