Capabilities of Diagonally-Cracked Girders Repaired with CFRP
The technique of using carbon fiber reinforced polymer (CFRP) for strengthening conventionally reinforced concrete (CRC) girders in flexure is well understood, but strengthening girders for shear is a newer application and less data are available. A literature review and survey were conducted to document the state of understanding and experience with respect to using CFRP for shear reinforcement of CRC girders. A laboratory investigation using full-size T- and inverted T-girder specimens with diagonal (shear) cracks was conducted to investigate the shear capacity improvement due to CFRP reinforcement and the effect of cyclic loading on CFRP shear strengthening. National and international code provisions for the design of CFRP in shear were used to compare the predicted shear capacity with the experimental results. An example application was included for using external CFRP strips to strengthen a bridge girder.
