Abstract
- Corrosion of reinforced bars and the fatigue effect in concrete structures significantly impact the bond performance of reinforced bars. The current research mainly focuses on the effect of fatigue or corrosion on the bonding properties of steel bars, which is still quite different from the service environment of the structure. The degradation law of the bond performance, failure characteristics, and changing trend of bond stress along the anchorage length of reinforced concrete specimens were analyzed under the combined action of fatigue and corrosion in this test. Under the combined action of corrosion and fatigue, the specimens’ bond stress and slip limit are significantly reduced, and the steel bars may fracture during the loading process. There are two peaks in the longitudinal distribution curve of the combined stress of the specimen under the combined action of fatigue and corrosion.
