In high-strength bolted friction joints, a diagram has been proposed to estimate slip resistance based on splice plate thickness reduction. However, considering the load transfer mechanism, the effect of corrosion varies with the bolt-row position. In particular, reduction around bolts in the outermost row, where corrosion tends to progress, is critical to investigate. This study investigates the relationship between plate reduction at each bolt row and slip resistance using finite element analysis. The results indicate that thickness reduction around the outermost bolts has only a minor effect on slip resistance, suggesting that the joint capacity is less sensitive to localized corrosion at these positions.
