Abstract | Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) U-wraps for shear strengthening of reinforced concrete (RC) bridge members remains uncertain due to the limited field experience with these materials. This paper provides experimental results from the testing of full-scale RC bridge girder specimens after exposure to prolonged freeze-thaw cycling. CFRP shear contributions seen in experimental results were estimated using a refined base capacity prediction (Response-2000) and compared to predicted CFRP shear contributions (ACI-440). A decrease in CFRP shear contribution was seen due to freeze-thaw exposure when moisture was present at the CFRP-concrete bond interface. |
