Carbon Fiber Reinforced Polymer Repairs of Impact-Damaged Prestressed I-Girders
Three different Carbon Fiber Reinforced Polymer (CFRP) repair techniques are examined to determine how effectively each method can restore the ultimate flexural capacity of impact-damaged prestressed concrete girders. The number of severed prestressing strands and the amount of CFRP repair material …
