Strengthening of reinforced concrete beams by using FRPs-An overview

Abstract

In recent years, the externally bonded reinforcing (EBR) method has been utilized to improve reinforced concrete (RC) constructions employing composites constructed of fiber reinforced polymers (FRP). Due to its strong nature, ideal reliability and suitability for use with concrete buildings when used, externally bonded Composites made of polymer with fibre reinforcement (FRP) are developing continually more popular in the construction sector for the treatment of degraded structures. This study's objective is to assess recent findings about the strengths, weaknesses, and potential of FRP enhanced constructions made of reinforced concrete (RC) under various situations for loading. In challenging environmental conditions that are static, dynamic, and environmental, FRP strengthening produces good results. Although it is yet unclear what causes debonding and FRP rupture when service loads and environmental exposures interact, these failure types are common. The acknowledgment of use of FRPs in enhancing RC constructions as techniques are developed for utilizing all of the material's strength, reducing brittleness and the danger of fires and unintentional damage decreasing usage of energy and carbon emissions the production process, and decreasing the material's significant upfront expense. The knowledge gaps according to the condition of the art are also identified in this report, along with possible FRP-enhanced structure research subjects that can advance knowledge and produce design standards.
