Abstract:An overview of a study on bond of glass fiber reinforced plastic (GFRP) reinforcing bars to concrete is presented. The 78 specimens to be tested include several variables, such as the mode of failure (i.e., pullout or splitting), concrete compressive strength, bar diameter, clear cover distance, and top bar effects. In addition, the effect of the radius of bend for hooked bars and the extension on the hooks are investigated. The study is currently in progress and the results of the specimens tested to date are presented. Preliminary results indicate that the top bar effects observed for steel reinforcing bars are also present for GFRP bars. For hooked bars, larger radii of curvature increase significantly the failure load of the bars.
