Abstract
On the orthotropic steel deck, thickness reduction of the deck plate sometimes occur due to rainwater from pavement crack and salt supplied by deicing agent. The one-sided plate bonding method, that can be done in a short time and do not affect traffic flow, for repairing the thickness reduction has been studied by bending tests and FE-analysis.
In this paper, the effect of the one side patch plate technique is confirmed by the static and fatigue wheel loading tests and FE-analysis, using the real-sized specimen with an introduced thickness reduction which simulates corroded damage. The stress distribution due to the different size or position of the thickness reduction area were also examined. In addition, it is confirmed that the required thickness of patch plates resulting from real-sized tests and analysis have conformed with the thickness design method for the corroded plate proposed in the previous study.
