The article presents an analysis of existing methods for determining the stiffness parameters of bent reinforced concrete elements reinforced with external reinforcement based on carbon fibers. The results of comparing the results of the determination of stiffness by practical methods and laboratory tests are presented. As a result, general conclusions and recommendations were made for further research of this issue, as well as the general parameters of the carbon fiber-based reinforcement system needed to be taken into account.

The article provides an analysis of the possibility of using carbon fiber-based external reinforcement systems to strengthen the load-bearing structures of beam arches along steel beams. The main conclusions based on the results of previously conducted laboratory studies on full-scale samples, as well as the results of the work performed on reference objects are presented. As a result, general conclusions have been drawn regarding the calculation and design, as well as recommendations for further research on the calculation and design of these systems.
