The article discusses the issues and features of modeling the external reinforcement of reinforced concrete structures during bending using the ANSYS software. A method for modeling flexible reinforced concrete elements reinforced in a stretched zone with external reinforcement made of composite materials based on carbon fibers, tested during field experiments, is presented. This was used as clarifying factors to develop a methodology with different approaches to the reinforcement of reconstructed reinforced concrete. Qualitative and quantitative relationships between experimental and numerical studies are established, confirming the prerequisites of the study. The limit values of deformations of concrete, steel reinforcement, composite reinforcement during destruction are determined. A comparative characteristic of variational approaches to modeling the joint work of external reinforcement and damaged concrete is given. Comparative analyses of the dependence of the increase in load-bearing capacity on the degree of damage and load of the element were also performed. Theoretical and actual values of the opening width and height of cracks in the zone of pure bending, including before and after reinforcement, are determined.
