Efficiency Of RC T-Section Beams Shear Strengthening With NSM FRP Reinforcement
Published 2011 · Materials Science
The paper analyzes an efficiency of a near-surface mounted (NSM) fiber reinforced polymers (FRP) technique for shear strengthening of reinforced concrete (RC) beams. A review of existing research shows that a number of experimental tests and engineering practice in this field is extremely limited. However, the first results have been very promising and aroused interest of the worldwide FRP community. Based on published test results, the paper provides a comparative study of failure modes, FRP strain efficiency and shear strength enhancement. The efficiency of the NSM shear strengthening is discussed in aspect of the following parameters: shape of the beam’s cross-section, beam’s dimensions, internal shear steel reinforcement percentage, type, cross-section, inclination and spacing of the NSM FRP reinforcement along the beam’s axis and the concrete strength.
