Shear Strengthening of R.C. Beams by using GFRP
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
Shear is actually a very complex problem and is not completely solved for simple reinforcement concrete beams. The current codes (American Concrete Institute (ACI), ISIS Canada and I.S.456:2000) qualify the nominal shear strength by means of a simple sum of the contributions of the concrete (Vuc) and the steel (Vus). For RC beams with externally bonded fiber reinforced fiber polymer (FRP) sheets, the Contribution of the sheets (Vuf) is added. Shear failure is catastrophic and occurs usually without warning; thus it is desirable the beam fails in flexure rather than in shear. Many RC members are found to be deficient in shear strength and needs to be repair. Externally bonded reinforcement such as FRP provides excellent solution in this case. The aim of the work were to check shear capacity of RC beams with different FRP orientation, to check authenticity of available analytical method to calculate shear strength of strengthened beams and to evaluate percentage increase in load carrying capacity of shear strengthened beam. The result of this research pointed out a general improvement in terms of shear capacity for the strengthened beams.
