AbstractRebar corrosion in reinforced concrete bridge decks is a major problem. Most technical solutions forthe problem attempt to slow the corrosion rate or prevent corrosion, but an alternate approach isreplacing the steel with a more durable material such as fiber reinforced polymer (FRP).The University of Sherbrooke, Quebec, Canada, recently conducted a field project in which FRP rebar and grids were used to reconstruct portions of a concrete deck slab that had severely deteriorated when the reinforcing steel corroded. The project included analysis and design of the bridge structure, construction of the concrete deck slab, and field performance monitoring of the completed construction using fiber optic sensors (FOSs). The integration of FOSs to monitor long-term performance of RC structures is a fairly recent development that deserves more attention from practicing engineers and field personnel.
