Some FRP strengthening projects in Australia

This paper discusses the FRP strengthening work in several bridge projects in Australia. The projects are the Southern Link Upgrade, M80 Ring Road Upgrade, Oyster Channel Bridge and Shepherd Bridge. The strengthening work was to improve the capacity of various bridge elements including pier crossheads, precast Ibeams, box girders, T-beams and pedestals. Several anchorage types were used and are described, including steel plates with anchor bolts, steel brackets, FRP U brackets and diagonal FRP patches. Comments on the difficulties in design and construction are also made.
