Book excerpt: Thermol characteristics of fiber reinforced polymer (FRP) reinforcement can be substantially different form those of concrete and conventional steel reinforcement. The influence of this difference on the behaviour of FRP reinforced concrete members is studied in this paper. Concrete beams reinforced with different types of FRP rebars are tested under the effects of temperature gradient while the rotation at the two ends of the beam are restrained. The bending moments and cracking developed by the thermal gradient are monitored. The results are compared with those obtained from tests on beam of the same dimensions but reinforced with steel bars. The behaviour of thermally cracked members is also investigated under mechanicl load effects at both service and ultimate load levels. The potential cracking of the concrete cover caused by the transverse thermal expansion of FRP bars is examined by testing concrete cylinders. The experiments show the difference in thermal behaviour of glass and carbon FRP and steel bars.
