The paper touches upon the issues and features of computer modeling of external reinforcement of reinforced concrete beams with the use of computer complex ANSYS. The method of modeling of bent reinforced concrete beams reinforced in the stretched zone by external reinforcement based on carbon fiber composite materials, approved by experimental studies, is presented. The explanations on application of a technique at various approaches to strengthening of a beam depending on the current stress-strain state are given. Qualitative and quantitative dependences between experimental and numerical studies are established, confirming the initial prerequisites of the study.
