Heavier traffic loads, poor initial design, aggressive exposure conditions, natural or man-made extreme events and steel reinforcement corrosion can all deteriorate the shear strength of existing reinforced concrete (RC) structures. Fibre reinforced polymer (FRP) shear strengthening solutions have emerged in response to the increasing number of shear-deficient RC structures. This talk addresses shear strengthening of existing RC beams with embedded FRP bars. First, a synthesis of beam test results will be presented. This will be followed by an overview of the research carried out at the University of Birmingham, which addresses existing gaps in knowledge and identifies the effect of the main parameters influencing shear behaviour, namely shear span-to-effective depth ratio, size effect and existing steel to FRP shear reinforcement ratio.
