Repair of Reinforced Concrete Bridge Columns via Plastic Hinge Relocation, Volume 2: Repair Using CFRP Materials

The goal of this report is to present a repair procedure for seismically damaged reinforced concrete bridge columns via plastic hinge relocation. To repair the damaged columns, carbon fiber (CF) anchors were utilized. Thus, the behavior of CF anchors was studied through various testing methods and design procedures were developed. In addition, the reliability of the proposed design procedure was shown with large scale testing.
