| Abstract: | Two carbon fiber reinforced polymer(CFRP) strengthened reinforced concrete(RC)beams insulated with thick-painted fire resistant coating were tested for fire resistance in accordance with the standard fire curve.The experimental results show that the specimen insulated with 50 mm layer of coating can achieve a fire resistance rating of 2.5 hours,and the steel wire mesh embedded in insulated layer can effectively prevent the layer from cracking and dropping under fire. |
