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

Figure 13

The plot of the ultimate bearing load of beams against various reinforcement methods for different CFRP length but with the same notch depth of 20 mm. (a) CFRP length of 100 mm, (b) CFRP length of 200 mm, and (c) CFRP length of 350 mm. A for without reinforcement, B for single-layer CFRP reinforcement, C for two-layer CFRP reinforcement, and D for single-layer CFRP reinforcement using U-shaped caps at the plate ends.
