Abstract:The bond strength between GFRP and clay brick is studied by experiments on a single shear test setup with emphasis on the effects of the GFRP bond length, bond width, type of bond resin and bond layer. Following conclusions are drawn from the study: 1) there are two kinds of failure modes, namely GFRP debonding failure and GFRP rupturing failure; 2) the bond length, bond width, type of bond resin, bond layer and compressive strength of clay brick have significant effects on utmost bond strength.

Keywords:GFRP； clay brick； single shear test； ultimate bond strength
