Abstract:
A series of R.C. beams were strengthened with carbon-fiber-reinforced plastic (CFRP) laminates and tested in an experimental program to study the influence of the cross-sectional area of the CFRP laminates on the shear capacity of the strengthened beam. The used technique enhances the flexural capacity of the original beam but at the same time may decrease the shear capacity. The strengthened beams are noticed to behave and fail through various modes. Also a general modified equation is proposed to predict the load carrying capacity of the strengthened beams taking into account all the existing parameters. The results obtained using the modified equation are discussed and evaluated according to the obtained experimental results.
