Abstract:This project consisted of the repair and strengthening of 11 prestressed concrete girders that were damaged by vehicular impact on Bridge A4845, Jackson County, Missouri. The repair/strengthening was achieved by externally bonded fiber reinforced polymer (FRP) reinforcement. Co-Force America, Inc., carried out the design for the repair/strengthening of the girders and provided quality control in the initial stages of the construction. Additional strips of FRP were installed by the University of Missouri-Rolla (UMR) for long-term bond durability studies in the form of bond pull-off and torsion tests. The initial tests have shown good adhesion of the laminate to the concrete substrate. Follow up tests will be performed at one-year intervals for the next 5 years. A separate report will be submitted by UMR once all of the bond durability tests are completed.
