Abstract

The fire resistance of concrete members reinforced with fibre reinforced polymer (FRP) rebars is extremely crucial area that needs to be investigated prior to implementing FRP composite materials in buildings. This work analyses the structural behaviour of concrete beams reinforced with hybrid FRP and steel reinforcements at elevated temperatures. The slice approach model was used and validated against experimental data for reinforced concrete beams with FRP available in the literature. Good agreement with experimental results has been obtained at room temperature as well as at elevated temperatures.
