摘要：Strengthening of concrete structures with bonding FRP laminates has been increasingly used in recently years. The effective bond between FRP and concrete substrate is a critical factor that affects strength. Based on the lateral shear experiment, the bond behavior of GFRP and concrete is analyzed. Test variables include surface preparation of concrete, concrete compressive strength, ratio of width for GFRP and concrete, width of GFRP, bond length of GFRP, etc. The results show that concrete strength, the width of GFRP and the bond length of GFRP have a significant influence on the bond behavior between GFRP and concrete. In addition, a suggested formula of bond strength for GFRP and concrete is presented.
