摘要

The bonding properties between GFRP rebar and concrete are tested and analyzed to ensure feasible application of GFRP rebar in concrete structures. It is found that the bonding strength between GFRP bar and concrete is comparable with that between steel rebar and concrete. Also when there is special surface treatment, the bonding can be significantly improved. Then concrete beams with GFRP rebar embedded as reinforcement are tested and analyzed. It is found that the bonding is acceptable, and the bending capacity is larger using GFRP rebar, except that serviceability is difficult to satisfy.
