The NSM-FRP approach involves cutting grooves into the surface of the beam and filling them with a suitable adhesive, such as epoxy paste or cement grout. The grooves are then filled with FRP materials having circular, square, or rectangular cross-sections. Variety of parameters towards the contribution of FRP materials’ amount such as the length, thickness, and width play a key role in the amount of resources needed such as material, manpower, cost, time, and tools in order to achieve the best strengthening effect. It is notable that the length of the FRP material bonded to the concrete substrate’s sides has an impact on the shear strengthening of RC beams with NSM-FRP technique.
