Abstract

Various reasons, such as design and construction errors, environmental attacks and functional changes often require shear strengthening of reinforced concrete (RC) beams. Shear strengthening may also be necessary as a result of flexural strengthening. Several studies have been conducted on shear capacity enhancement of CR beams using externally bonded fiber reinforced polymer (FRP) composites. If such strengthened beams should fail in shear, the failure mainly occurs in one of the two distinct modes: debonding of the FRP from the beam and FRP rupture. Presented is a rational shear strength model for shear strengthened RC beams that fail due to FRP debonding. The strength model is validated against experimental data collected from the literature, and a design proposal is developed based on this new model.
