Abstract: To explore the influences of temperature changing on mechanical properties of bricks reinforced by the fiber reinforced plastic (FRP) sheet, tests on mechanical properties of glass fiber reinforced plastic (GFRP) sheet, carbon fiber reinforced plastic (CFRP) sheet, clay brick, shale brick and epoxy resin were conducted under temperatures between −20 ℃~60 ℃, and the changes of material properties were explored. Afterwards, the single-lap shear and pull-off tests on FRP reinforced single brick and FRP reinforced brick masonry walls were conducted, and the equation of single-lap shear strength of the interface between FRP and bricks was proposed based on the experimental results. It is shown that the tensile strengths and elastic moduli of CFRP and GFRP sheets are not significantly changed at the temperature of −20 ℃ compared with those under room temperature, however, the compress strength of bricks and tensile strength of the epoxy resins have a 17.19% and 29.69% decrease respectively. The rise and fall of the temperature will decrease the pull-off strength and single-lap shear bond strength of the interface between FRP and bricks. For CFRP reinforced clay bricks under temperatures of −20 ℃, 40 ℃ and 60 ℃, the pull-off strength has 10.40%, 7.50% and 13.95% decrease, respectively, and the single-lap shear bond strength has 6.48%, 5.23% and 7.80% decrease, respectively. The single-lap shear bond strength of FRP-brick masonry walls is lower than that of FRP-bricks under the same condition. The proposed equations can accurately predict the degradation performance of single-lap shear bond strength under different temperature conditions.
