Torsional strengthening of concrete members using CFRP composites: A state-of-the-art review

The use of carbon fibre reinforced polymer (CFRP) composites in reinforced concrete members has emerged as one of the most promising technologies to address the rehabilitation requirements of buildings and bridges. Both externally-bonded reinforcement (EBR) and near-surface mounted (NSM) techniques have been investigated by many researchers, both experimentally and theoretically. The aim of this paper is to present a review of the literature concerning the torsional behaviour of reinforced concrete beams strengthened with CFRP.
