The choice of options for strengthening reinforced concrete structures is based on a large number of factors based on technical capabilities and economic efficiency. Modern construction requires new reinforcement methods that allow reducing labor costs and work time, while maintaining the aesthetic appearance of a building under construction or being restored. The stumbling block is the issue price and the reliability of new amplification methods. For this purpose, known and used reinforcement methods based on materials such as reinforced concrete and metal were compared with a fairly new reinforcement method used materials based on carbon fabric. This article provides examples and results of calculations for the reinforcement of a column with a reinforced concrete, metal and composite cage. Based on the results of the calculations, a technical and economic comparison of the existing reinforcement options was carried out.
