An overview of a study on bond of Glass-fiber-reinforced-plastic (GFRP) rebars 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 is being 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 effect observed for steel rebars is also present for GFRP bars. For hooked bars, larger radii of curvature increases the failure load of the bars significantly.
