摘要：

Pull-out specimens were used to study the effect of temperature ranging from 20°C to 190°C in dry environment on bond properties between glass fiber reinforced polymer (GFRP) bars and concrete. Experimental evaluations were carried out based on C30 concrete cubes and GFRP bars with the diameter of 8 mm. The experimental program consists of three parts: first, measuring the material properties of GFRP bars and concrete; second, confirming the interface bond strength and the associated slip values at both ends of the adhesive specimens in different temperature; third, the residual bond stress and the associated slip values at both ends of the adhesive specimens in different temperature were also measured. Confirming the parameter based on experimental results is useful for theoretical study on bond-slip constitutive relationship between GFRP bars and concrete.
