Abstract
Present paper investigates the efficiency of basalt fiber reinforced polymer bars (BFRP) for near surface mounted (NSM) strengthening of RC beams. An experimental program was carried out to determine the pullout behavior of BFRP bars and based on the results, an BFRP-NSM method has been designed. To assess the bond behavior of BFRP to concrete, pullout tests were carried out. The influences of bonded length, groove size and diameter of bar on the bond behavior were analyzed. Based on the results, a ratio of groove size to diameter has been proposed to utilize the maximum potential of BFRP bars in NSM strengthening. Flexural strengthening of RC beams were carried out by using BFRP-NSM method. The diameter of the bar, number of bar and groove size were considered as the influencing parameter. Based on the studies, it is concluded that it is possible to double the load carrying capability without loosing ductility by using this method.
