Bond Characteristics of GFRP Sheet on Strengthened Concrete Beams due to Flexural Loading

Abstract—Fiber reinforced polymer (FRP) has been applied to many purposes for civil engineering structures not only for new structures but also for strengthening of the deteriorated structures. The application of FRPs in various forms such as rod, grid and sheet are widely accepted solution due to its corrosion resistance as well as high tensile strength to weight ratio. Glass composed FRP (GFRP) sheet is most commonly used due to its relatively lower cost compared to the other FRP materials. GFRP sheet is applied externally by bonding it on the concrete surface. Many studies have been done to investigate the bonding of GFRP sheet. However, it is still very rarely studies on the bonding behavior of GFRP sheet on the strengthened beams due to flexural loadings. This is important to be clarified for the wider application of GFRP sheet especially on the flexural structure such as highway bridge girders. This study presented the results of experimental investigation of the bonding behavior on the strengthened concrete beams due to flexural loadings. A series of concrete beams strengthened with GFRP sheet on extreme tension surface were prepared. Results indicated the bonding distribution along the GFRP sheet due to flexural loading tended to be non-linear. The bond stress due to flexural loading was lower than the direct shear bond stress.

Index Terms—Flexural, bond stress, strengthening, GFRP sheet.
