The article presents the results of experimental studies of the mechanism of force transmission through cracks in reinforced concrete elements strengthened with external reinforcement from carbon-fiber materials. New results to assess the ultimate shear resistance and stiffness of sections of reinforced concrete elements with cracks are described.
