Experimental Study on Concrete T-Beams Strengthened with Carbon Fiber Reinforced Polymer (CFRP) Sheets on Three Sides

In this paper, through test of concrete T-beams strengthened with carbon fiber reinforced polymer (CFRP) sheets on three sides, the failure modes, ultimate flexural limit states and designing demands are discussed. The allowed stress of carbon fiber sheets is also analyzed according to the measured stress, which is important in civil engineering.
