| Outline of Final Research Achievements |
Recently, the corrosion damage on steel plate girders has been often reported. In particular, a section loss and a plate thickness reduction of steel plate girders seriously damaged by corrosion are concentrated in bridge girder ends, and the damage leads bridge failure in the worst case scenario. Since it is estimated that the corrosion damage of steel bridges greatly increases, effective and efficient repair methods are required. In this research, the recovery shear strength for ends of steel plate girders damaged by corrosion are investigated. This study focuses on the repair method with carbon fiber sheets for shear panels. As a result of tests, the good specimen of shear strength, load carrying capacity and elongation performance, has been proven to be with low elasticity adhesives.
