An Experimental Study for a Fatigue-Bond Behavior of RC Structures Considering a Reinforcement Corrosion and a Fatigue Loading

There are many structures attacked by chloride ions near a marine environment. And they are attacked by a salt of de-icing chemicals. So, the embedded reinforcement is corroded. In the same time, these are under a fatigue loading by a traffic loading in bridges. In previous studies, there are many researches that deal with a bond behavior under a monotonic loading according to the rate of a steel corrosion. But there are most cases that the steel corrosion and the repeated loading are acted on structures simultaneously. So, in this study, it is investigated a fatigue-bond behavior of RC structures under a steel corrosion and a fatigue loading. Main variables of the test are a corrosion of steel reinforcement and a level of stress.
