| 摘要： | A research project was recently complete to assist the Florida Department of Transportation in establishing a list of acceptable methods for the repair of impact damaged prestressed concrete bridge girders using fiber reinforced polymer (FRP) materials. Over the last several years numerous bridges throughout the state have been stuck by over-height vehicles and successfully repaired by the FDOT using FRP on an experimental basis. One of the main efforts of the project was to standardize the type of repair procedures used in the field for impact damaged prestressed concrete girders. The experimental portion of the research consisted of testing six full-scale, 44 feet long AASHTO Type II girders. The tests represented an undamaged control specimen, a control specimen with simulated damage, and four specimens with simulated damage that were then repaired with different fiber reinforced polymer systems. The FRP systems varied in material type, laminate properties, application procedures, reinforcing schemes, and repair design procedures and assumptions. The specimens were tested to failure to determine moment and shear capacities, as well as deformation and ductility behavior of the undamaged, damaged, and repaired girders. |
