| Abstract: | The material properties of FRP and bond behavior of FRP and concrete after the wet-thermal aging are experimentally analyzed. In addition, the influence of the wet-thermal aging on the concrete structures strengthened by FRP is studied. The test results for GFRP specimens subjected to wet-thermal action showed a decreasing trend, whereas for CFRP specimens showed no obvious change. Under wet-thermal condition, there is an obvious decrease for the bond strength between FRP and concrete, and the durability for FRP strengthening concrete structures also declines. |
| Keywords: | FRP wet-thermal condition concrete structures durability |
