Fire Resistance
Fire Resistance of GFRP Fiberglass Rebar in Concrete
Design codes have been released for the use of GFRP in civic structures and they take into consideration fire resistance. Research indicates that concrete fails before GFRP fails and that as a rule of thumb if a fire is bad for GFRP it is similarly bad for steel reinforcement. Some exceptions exist.
Failure of beam 2 after fire test inside the furnace shows some flexural cracks and rupture in the main reinforcement.
Design guides have been published and should be carefully followed.
