Abstract

Fiber-reinforced polymer (FRP) bars are increasingly used in the construction industry as a potential alternative to steel thanks to the advantages of their physical-mechanical properties, their high resistance to corrosion and their high strength ratio. / weight, compared to ordinary reinforcement. However, aspects such as its low ductility, its low modulus of elasticity and its low resistance to high temperatures are limiting for its use as a reinforcing material in concrete structures. This fact has raised real concerns that are hampering the general acceptance of the material today. To this end, this article provides a review of existing research that studies the behavior and properties of both the FRP itself, as well as the reinforcement integrated into the concrete, in structures that are exposed to fire situations. It also analyzes the experimental results and numerical studies carried out by various researchers for insulated and non-insulated FRP reinforced concrete elements (beams, columns, slabs) at elevated temperatures. Finally the available design guidelines are discussed.
