Abstract EN
The effectiveness of externally bonded sprayed glass fiber reinforced polymer (Sprayed GFRP) in shear strengthening of RC beams under quasi-static loading is investigated.
Different techniques were utilized to enhance the bond between concrete and Sprayed GFRP, involving the use of through bolts and nuts paired with concrete surface preparation through sandblasting and through the use of a pneumatic chisel prior to Sprayed GFRP application.
It was found that roughening the concrete surface using a pneumatic chisel and using through bolts and nuts were the most effective techniques.
Also, Sprayed GFRP applied on 3 sides (U-shaped) was found to be more effective than 2-sided Sprayed GFRP in shear strengthening.
Sprayed GFRP increased the shear load-carrying capacity and energy absorption capacities of RC beams.
It was found that the load-carrying capacity of strengthened RC beams was related to an effective strain of applied Sprayed GFRP.
This strain was related to Sprayed GFRP configuration and the technique used to enhance the concrete-FRP bond.
Finally, an equation was proposed to calculate the contribution of Sprayed GFRP in the shear strength of an RC beam.
