• 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.
