| Abstract: |
Recently, corrosion damages on upper surfaces of orthotropic steel deck plates are often found during the bridge pavement repair work in urban expressways. Repair methods for these damages are required to be finished quickly, for example within one or two hours, during the pavement repair work. In addition, decrease of thickness or pitting corrosion will lead to stress increase and the acceleration of fatigue damage. In this study, the authors focused on the repair method of bonding steel patch plates from the upper surface side. In order to investigate the basic mechanical behaviour, finite element analysis and bending tests of thickness-reduced plates repaired with bonding steel plate under bending were carried out. Simple equations for designing the thickness and length of patch plate repair were proposed. |
