Effect of Bonding Area on Bond Stress Behavior of GFRP Bars in Concrete

نویسندگان

چکیده

The application of Glass Fiber Reinforced Polymer (GFRP) bars is suitable for concrete structures that are susceptible to corrosion, owing their corrosion-resistant characteristics. Therefore, it feasible reduce the cover on reinforced beams by utilizing GFRP bars. However, this can bonding strength between and concrete. study aims investigate behavior as a preliminary test structural applications. bond stress was analyzed 18 pull-out tests. specimens comprised with three different variations, namely (GFRP-C), without (GFRP-E), complete wrapping sheet (GFRP-C-Sheet). stress-slip curve, strength, failure pattern were utilized analyze effect each variation. research results indicate strongly influenced cover, where decreased 65%. Nevertheless, utilization GFR) resulted in 26.4% increase stress. present has identified distinct modes failure, including crushing debonding Doi: 10.28991/CEJ-SP2023-09-010 Full Text: PDF
