Shear Strengthening with CFRP
Shear failure is catastrophic and usually occurs without warning. Many existing reinforced concrete (RC) members are found to be deficient in shear strength and need to be reinforced. Externally bonded reinforcement such as carbon-fiber-reinforced polymer (CFRP) is an excellent solution in these situations.
Simply orienting CFRP fibers transverse to the axis of the member or perpendicular to potential shear cracks is effective in providing additional shear strength. This strengthening technology has numerous advantages over conventional steel plating, such as providing a high strength-to-weight ratio, versatility, durability, resistance to corrosion and ease of use.
