| Abstract: | The debonding behavior at the interface between FRP sheet and concrete is a key problem for the application of FRP in concrete structure strengthening.Applied the method of the damage mechanics,the damage variable of the interface bond-slip between FRP sheet and concrete is defined.The damage model and the formulas for calculating the damage of interface are presented,and the damage mechanism of the bond-slip failure for the application of FRP in concrete structure strengthening are expounded. |
