초록
The effects of concrete strength on bond-slip behavior and the failure mechanisms of glass fiber reinforced polymer (GFRP) bar embedded in concrete under direct pullout were investigated in this study. Total of twenty seven specimens were prepared by placing two different types of GFRP bars and conventional steel rebar in 25 MPa, 55 MPa, and 75 MPa concrete and tested according to CSA S806-02. The test results showed that the bond strength of the GFRP rebars as well as the steel increased with the concrete strength. However, the increase in the bond strength with respect to the concrete strength was not as significant in the GFRP series as the steel, and it was attributed to the interlaminar failure mechanism observed in the GFRP test specimens.
