A comparative study of three reinforcement options for reinforced concrete beams has been carried out: without reinforcement, with reinforcement with carbon tape both along the entire span length, and with partial reinforcement of the span zone with an end mechanical anchoring with carbon bundles. Numerical modeling has been performed, diagrams of bending moments and force distribution have been constructed, and the coefficients of the safety margin of the construction system have been estimated. The effectiveness of the schemes is substantiated in terms of strength, taking into account manufacturability and material consumption. It is shown that the use of mechanical anchoring with harnesses increases the reliability of the system while reducing material consumption.

The article discusses the use of carbon anchor harnesses to strengthen building structures. Their design features, installation technologies, and key advantages, including low weight, high strength, corrosion resistance, and durability, are described. An overview of existing experiments demonstrating the reliability of anchor harnesses under load, their effectiveness in preventing the stratification of external reinforcement elements and increasing the strength of joints is given. The shortcomings of the regulatory framework and the lack of practical recommendations on the selection and design of anchor harnesses are indicated. The authors emphasize the need for further research to optimize the interaction of the elements of the reinforced structure-external reinforcement-anchor system.
