Experimental Investigation of RC Corrugated Beams Strengthened with FRP Sheets
Steel corrosion in concrete is one of the main causes for the degradation of the structural members. Corrosion of steel causes internal damages in the reinforced structures which effects the durability and performance of the structure. In current investigation, total of 13 beams of size 1 m × 0.15 m × 0.15 m were casted and beams are subjected to accelerated corrosion, rates are varied incrementally by 5–15% and the beams were strengthened with carbon fiber-reinforced polymer (CFRP) sheets, glass fiber-reinforced polymer (GFRP) sheets, and CFRP plus GFRP sheets together and compared with controlled beam. Load-carrying capacity, flexural strength, ductility, and toughness are studied. Investigation shows that the beam strengthens with combination of CFRP and GFRP shows a better load-carrying capacity as compared to controlled beam; however, it can even achieve good results if bonding strength between sheets and beams is taken in consideration.
