In this study, a characteristic of residual axial force for corroded high-strength bolts was investigated. Corroded bolts cut from a steel bridge were used for the measurement of thickness reduction and residual axial force. The experimental results showed the residual axial force has a good correlation with the summation of thickness reduction. An FE analysis examined the effect of the corroded shape of bolts on the residual axial force. The analytical results revealed that the effect of corroded shapes on the residual axial force can be considered by the thickness reduction near the washer.
