Currently, the remaining riveted bridges are almost over 60 years old. Therefore, the rivets are corroded and loosen over time, deteriorated the condition of the bridges further. Previous studies have shown that replacing the riveted joints with a high-strength bolt for friction is considered the best approach to repairing the riveted joint in steel bridges. However, the current state is that the load transfer mechanism of the rivet and high-strength bolt friction joints is still unknown, and the load capacity of the combined joint has not been sufficiently discussed. Technical standards and design methods for repair have not been established. This study examined the load transfer mechanism and repair application range of the combined joint using the tensile test and FEM analysis.
