Influence of Reinforcement Load Level on Bearing Capacity of RC Beams Externally Reinforced with СFRP by Gennadiy A. Smolyago, Alexander E. Zhdanov, Yana L. Obernikhina

“…At the same time, there are a limited number of systematic studies of the effect of preload on the bearing capacity of reinforced concrete beams reinforced with carbon fiber. This article presents a methodology for assessing the effect of the stress-strain state level of reinforcement on the bearing capacity and other parameters of the sections of bent reinforced concrete elements reinforced with carbon fiber, taking into account the physical nonlinearity of concrete and using real deformation diagrams, including reinforcement and reinforcement systems. …”
