An Experimental Investigation on the Failure Behavior of a Notched Concrete Beam Strengthened with Carbon Fiber-Reinforced Polymer

(a) The effects of initial notch depth on the ultimate bearing capacity of concrete beam without CFRP strengthened; (b) the effect of CFRP length on the ultimate load bearing capacity of reinforced concrete beam for the notch depth of 10 mm; (c) the effect of CFRP length on the ultimate load bearing capacity of reinforced concrete beam for the notch depth of 20 mm; (d) the effect of CFRP length on the ultimate load bearing capacity of reinforced concrete beam for the notch depth of 30 mm.
