Precracked Reinforced Concrete T-Beams Repaired in Shear with Prestressed Carbon Fiber-Reinforced Polymer Straps
To date, fibre reinforced polymer (FRP) shear strengthening systems have primarily been applied as bonded passive systems which do not influence the shear behaviour of concrete structures until the concrete has cracked or existing cracks widen further. Such systems debond from the concrete at about 30% of the ultimate strength of the FRP reinforcement. This EPSRC-funded novel work presents a prestressed strap system that eliminates the limitations of the bonded systems and provides active confinement to the concrete. This ready for use system enhances the resilience of existing concrete infrastructure and reduces the carbon emissions associated with building new infrastructure.
