Abstract: This study presents the results of an experimental study aimed at investigating the flexural behavior of Reinforced Concrete (RC) beam retrofitted with Glass Fibre Reinforced Polymer (GFRP) by using Near Surface Mounted Method (NSM) when exposed to an elevated temperature. A total of 7 numbers of 150×150×750 mm RC beams were tested under a three-point bending test. The experiments results show that the flexural strength of all the control specimens decreased with increasing temperature. However, the GFRP retrofitted specimens improves the flexural strength of the beam specimens by 50, 44 and 43% for specimens burned at 200, 600 and 800°C, respectively as compared to the control specimen. Therefore, NSM retrofitting method with GFRP is proven to be effective to maintain a beam structure that was exposed to the elevated temperature.
