Abstract

To the calculation of the deflections of the reinforced concrete columns strengthened with composite materials

Georgiev S.V.

The article presents data on the effect of external composite reinforcement of reinforced concrete columns on their deformation properties. It is established that the results of calculations of the reinforced samples according to the deformation norms in force have significant discrepancies with experiment. Based on the analysis of the results of experiments, proposals have been introduced into the normative calculation of deflections, which take into account the type and percentage of composite reinforcement and ensure good agreement between the experimental and theoretical data.

Keywords: concrete, reinforced concrete, composite material, carbon fiber reinforced plastic, external reinforcement, deformations, deflections, compressed elements
