• Abstract:
  This report is an extension to the final report for NCDOT project 2004-15 “Value Engineering and Cost-Effectiveness of ; Various Fiber Reinforced Polymers (FRP) Repair Systems”, submitted in June 2005. In that report, seventeen 30-ft long ; prestressed concrete c-channels were tested under static and fatigue loading conditions using various carbon fiber reinforced ; polymer (CFRP) strengthening systems to determine their structural behavior, cost effectiveness and constructability. The 2004- ; 15 final report also included the behavior of impact damaged AASHTO girders repaired by CFRP systems and tested under ; fatigue loading conditions. ; This final report for NCDOT project 2006-10, summarizing the results of Phase II of the NCDOT project 2004-15, includes ; the behavior of four additional c-channel prestressed concrete girders strengthened with externally bonded high modulus CFRP ; sheets and high strength steel reinforced polymer (SRP) wire mesh. The report includes also the behavior of four additional ; AASHTO type II girders. Two long-span AASHTO girders were tested static loading conditions to assess the performances of ; FRP systems designed to repair impact damage. Two AASHTO girders were tested using short spans to determine the ; effectiveness of using FRP to restore the shear capacity of impact damaged girders with one girder tested as control specimen and ; one damaged then repaired with FRP. The repaired girder was stronger than the damaged girder, indicating that the FRP repair is ; effective in restoring the girder shear capacity. ; Based on the above, the entire experimental program consisted of twenty-one girders strengthened with various FRP and ; SRP materials and five AASHTO girders repaired with FRP to restore their flexural and shear capacities. The research indicates ; that FRP systems are effective for the strengthening/repair of concrete highway bridges. The report provides detailed procedures ; for installation as well as efficient inspection procedures to ensure effectiveness of the strengthening/repair systems.
