Repair and Strengthening of Distressed/Damaged Ends of Prestressed Beams with FRP Composites
The Illinois Center for Transportation at the University of Illinois at Urbana-Champaign has released a report that describes a study that uses fiber reinforced polymer (FRP) materials to repair and retrofit the damaged ends of prestressed concrete beams. FRP composites have emerged as a lightweight material to repair and retrofit concrete infrastructures, but one problem in cold climates is the deterioration of the girder ends due to deicing salt exposure, thus reducing FRPs’ shear strength.
