Riveting was mainly used in the assembly of steel members and steel plates of bridge prior to the establishment of bolting and welding. To preserve the aged bridges with riveting, it is assumed that the damaged rivets are removed and replaced with new rivets. When a rivet is placed on the existing structural members for repair, the member expands and shrinks caused by heat input during placing the rivet. Although this heat input generates the residual stress, the features of residual stress by riveting is not clear. In this study, a series of experiment and analysis was performed for investigating the generation mechanism of residual stress by rivet joining.
