AbstractFire resistance experiments were conducted at the National Research Council of Canada (NRC) in partnership with Intelligent Sensing for Innovative Structures (ISIS) Canada and Fyfe Co. LLC, to investigate the behaviour of FRP-strengthened reinforced concrete slabs and beam-slab assemblies under exposure to a standard fire. The slabs and beams were provided with a unique supplemental fire protection system. The results of fire endurance experiments on two full-scale FRP-strengthened reinforced beam-slab assemblies and two intermediate-scale FRP-strengthened reinforced concrete slabs are described in this report. These experiments were conducted as part of a collaborative research program aimed at studying fire endurance of reinforced concrete members strengthened with externally-bonded FRP systems. The results suggest that by providing proper supplemental fire insulation, as described in this report, fire endurance ratings of up to four hours can be achieved for loaded FRP-strengthened reinforced concrete beam-slab assemblies.
