Behavior of RC Beams externally strengthened with GSM & CFRP sheets
This paper examines the behavior of reinforced concrete beams strengthened in flexure with galvanized steel mesh (GSM) sheets and carbon fiber reinforced polymers (CFRP) sheets. A total of three RC beams specimens were examined under a four-point loading test. One beam was strengthened with GSM sheets, another was strengthened with a CFRP sheet with about the same reinforcement ratio to GSM specimen, and the final beam was set aside unstrengthened as a control specimen for comparison. The ultimate load and deflection, and the load-deflection curves for all the tested specimens were recorded. The reported test results revealed that the GSM strengthened specimen increased its ultimate load-carrying capacity by 58% when compared to the control specimen. In addition, the CFRP strengthened specimen ultimate load-carrying capacity increased by 47% when compared to the same control specimen. Thus, the RC beam strengthened with GSM sheets has a larger load-carrying capacity than that of RC beam strengthened with CFRP sheet. Thus, it could be concluded that GSM laminates are a good substitute for CFRP laminates.
