Strengthening Reinforced Concrete Structures with FRP Composites
A hybrid FRP system for strengthening RC beams with a T-shaped cross-section, representing the deck and girder system of RC bridge superstructures, was also investigated.
Fibre reinforced polymer ( FRP ) composites have been widely used as externally bonded reinforcement (EBR) for strengthening RC structures since the 1990s. The work of this thesis aimed to investigate robust and efficient FRP - strengthening systems for structural strengthening of existing RC structures with a focus on RC bridge superstructures.
