Tab. 3 suggests that the test values were close to the simulated values, and the errors were all lower than 10%. The strains of the rebars and CFRP plates were analyzed using universal methods, and there were also small errors between the tested values and simulated values. The results suggested that the finite element model had a high accuracy.
