This After certain period of time, concrete structure elements require Re-construction or Rehabilitation, due to different reasons as mechanical damage, environmental effects, increased service loads, and errors in design and construction. Since past few decades, Near-Surface Mounted (NSM) technique using Glass Fiber-Reinforced Polymer (GFRP) bars has become an effective to increase flexural strengthening of existing Reinforced Concrete (RC) beam. This technique involves grooves cut such that the depth of groove must be less than the concrete cover. The grooves are partially filled with epoxy, into which FRP bar are placed, later these grooves are fully filled with epoxy. In total five RC beams were casted and tested under two-point load system. The main aim of this is to study the structural capacity by varying the amount of flexural reinforcement and spacing of stirrups. The experimental results shows that strengthening with NSM FRP bars significantly increase the flexural and shear strength compare to the control specimen. This technique will eliminate or reduces the crack width and growth rate, delay initial cracking and extend the life of RC beams.
