| Abstract | This paper proposes the use of the general method based on the modified compression field theory (MCFT) adopted by CSA-A23.3-04 to improve CSA-S806-02 estimation of the shear strength of reinforced concrete (RC) beams strengthened with fiber reinforced polymers (FRP). The estimations are compared with the results of four existing standards for shear design of reinforced concrete beams strengthened with FRP: CSA-S806-02, ISIS-M04-01, ACI-440.2R-08, and JSCE (2001). The accuracy of standards and the proposed approach are evaluated against an experimental database of 150 beams tested by various researchers. The results indicate that the proposed approach provides better estimats than existing approaches. Although the prediction of the shear capacity of the beams strengthened with FRP is generally acceptable, this paper highlights the importance of improving shear design to reduce scatter between different design standards and test results. The findings from this comparison represent a first step toward the development of a more rational shear design method for reinforced concrete beams shear strengthened with externally bonded FRP. |
