The paper deals with the issues and features of modeling of external reinforcement of reinforced concrete structures with bending using ANSYS software. The technique of modeling of the bent reinforced concrete elements strengthened in the stretched zone by external reinforcement from composite materials approved by full-scale experiments is given. This clarification of the application of the methodology with different approaches to the strengthening of the structure. The qualitative and quantitative dependences between experimental and numerical studies confirming the prerequisites of the study are established.
