The behaviour of Fibre-Reinforced Polymer (FRP) bars and Fibre-Reinforced Polymer reinforced concrete (FRP-RC) members under fire exposure is quite different from conventional means. This may be attributed to the complex behaviour of the bars when they are subjected to fire, as well as to the complexity of fire test procedures. The thermomechanical properties of FRP bars depend on the chemical composition of their constituents, their interface performance and the production process. The choice of the type of fibres and matrix with characteristics suitable for the desired purpose, as well as their balanced proportions in FRP bar can be the key factors affecting the overall resistance of an FRP element in the event of fire. The work presents a theoretical background and is intended to identify existing gaps in knowledge to justify the need for the present study.
