FRP reinforcement

Early in August of 1997, the province of Québec decided to construct a bridge
using carbon FRP reinforcement. The Joffre Bridge, spanning the Saint Francois
River, was another contribution to the increasing number of FRP-reinforced
bridges in Canada. A portion of the Joffre Bridge concrete deck slab is
reinforced with carbon FRP, as are portions of the traffic barrier wall and the
sidewalk.
The bridge is outfitted extensively with various kinds of monitoring instruments
including fibre-optic sensors embedded within the FRP reinforcement (these are
referred to as smart reinforcements). Over 180 monitoring instruments are
installed at critical locations in the concrete deck slab and on the steel girders, to
monitor the behaviour of the FRP reinforcement under service conditions. The
instrumentation is also providing valuable information on long-term
performance of the concrete deck slab reinforced with FRP materials.
