Structural Behavior of Concrete Flange Continuous Deep Beams with Carbon Fiber Reinforced Polymer (CFRP)

Abstract

The load capacity and behavior of a reinforcement concrete deep beam at each loading stage based on the geometric property of the section, steel arrangement, load and support condition. The current study used to inspect the structural response of continuous reinforcement concrete deep T-beams reinforced with the carbon fiber reinforced polymer (CFRP) failed in shear. The study analyzed three concrete deep T- beams, these beams contain CFRP reinforcement and three concrete deep T- beams, these beams contain steel reinforcement for comparison. The deflection, failure mode, crack pattern also studied at analysis. the shear failure is predominant for all analysis T-beams. And the result shows when keeping the rate of the CFRP reinforcement constant and increasing a/d ratio substantially affects the shear strength and the collapse loads decreasing, also the CFRP reinforced T-beams can be showed the shear strength value higher than those of similar steel reinforced T-beams.
