FRPs for the structural engineer
– Interest of the Ministère des Transports du Québec (MTQ)
– Live load rating factor LLRF = ( C1R – C2D) / C3L
– LLRF › 1 QS 660 satisfied– 0.85 ‹ LLRF ‹ 1 Legal load acceptable
– Forbidden to overloaded trucks
– Reinforcement recommended
– LLRF ‹ 0.85 Legal load excessive– Reduced maximum load posted
– Reinforcement compulsory

FRPs for the structural engineer
– Interest of the Ministère des Transports du Québec (MTQ)– Observation
– Bridge condition directly related to its LLRF – Bridge in good condition FCS – Bridge in poor condition FCS
– Search for a demonstration project– Identify a bridge in need of reinforcement (FCS < 1),
representative of a large number of existing bridges, and with a concrete surface condition that would allow easy installation of FRPs

FRPs for the structural engineer
– Interest of the Ministère des Transports du Québec (MTQ)
– Evaluate FRPs as strengthening method
– Aim at 33 % of cost of new construction– Accessibility to majority of contractors– Minimal technical training for
installation/supervision– Design methods available to design engineers

– Conclusions– Repairwork
Repair of concrete surface was more difficult than anticipated
Installation of flexural FRP reinforcement was relatively easy

– Conclusions– Repairwork
Special care was required in removing air trapped between the FRP and concrete surface for shear reinforcement, and to prevent slip during installation
It was necessary to heat the construction area for proper curing due to low temperature (October 1998)

– Conclusions– Monitoring
Readings from conventional gauges and LVDTs confirmed the anticipated behaviour of the FRP-strengthened structure under static loading
Readings of the fibre optic sensors are comparable with those of the conventional gauges
