AbstractThe deterioration of reinforced concrete infrastructure around the world has led to the use of fibre-reinforced polymers (FRP) in civil engineering applications. Two applications for which these materials have shown an almost immediate promise are wrapping of reinforced concrete columns and internal reinforcement of concrete slabs. However, there are serious concerns associated with the behaviour of these materials at high temperature, as would be experienced in case of fire, which need to be addressed before FRP can be widely accepted for use in structures other than bridges. This paper presents preliminary results from a study to investigate the effects of fire on FRP-wrapped reinforced concrete columns and FRP bar or grid reinforced concrete slabs. Preliminary numerical modelling indicates that FRP reinforcements are particularly sensitive to fire and that special fire design considerations are both warranted and necessary when using FRP as either internal or external reinforcement for concrete.
