Abstract
To the determination of the relative deformation of reinforced concrete εb3 of compressed reinforced concrete flexible columns strengthened with composite materials located in the transverse direction
Incoming article date: 20.10.2020The article provides data on the influence of external composite reinforcement of reinforced concrete compressed elements on their deformative properties. It was found that the deformations of reinforced samples, found according to the current standards, have significant discrepancies with the experimental values. Based on the analysis of the results of experiments, proposals were made to the methodology of norms for calculating the ultimate compressive deformations of concrete εb3, which take into account the type and percentage of composite reinforcement and ensure a good agreement between the experimental and theoretical values.
