This paper presents the effect of rehabilitation of thickness-reduced steel plate repaired by bonding or bolting patch plates. Generally, the thickness of patch plate is designed by using composite section of thickness-reduced plate and patch plates. However, it has been reported that the stress introduced in thickness-reduced region becomes larger than that calculated by composite theory when the patch plates are adhered onto the thickness-reduced plate. This is because the assignments of cross-section forces in thickness-reduced plate and patch plate are different from those calculated by composite theory. Thereby, this phenomenon will also be seen in the thickness-reduced plate repaired by bolting the patch plates. In this research, the tensile tests of thickness-reduced steel plate repaired by bonding or bolting patch plates were carried out. As the results, the strain in thickness-reduced region became larger than that given by the composite theory in both cases, and became the yield strain earliest.
