Design and technological solutions for reinforcing of bending concrete structures with composite materials based on carbon fiber are considered. The used systems for strengthening reinforced concrete structures are re-vealed. A comparative analysis of existing reinforcement systems based on carbon fibers is carried out. The economic efficiency of this reinforcement method for bending concrete elements is determined. The calculation technique for bending concrete elements reinforced by composite materi-als is given. The calculation of reinforcement by various composite materials is made on the example of reinforced concrete elements: a beam and a monolithic floor slab. The comparison of various amplification variants is made and the conditional utility coefficient is proposed, which makes it possible to economically justify the choice of the gain method and to predict the cost of strengthening the structure.
