“…The values of increase in the ultimate strength ranged between 45% and 52% for the beams strengthened with CFRP fabrics, whereas by using CFRP laminates, these values reached to 42% and 66% depending on the arrangement of laminates. A similar study explored the potential use of three various types of CFRP systems for shear strengthening of rectangular deep beams (Islam et al, 2005). In general, although the use of CFRP grids in normal orientation was adopted as the most effective system concerning the amount of material consumed, other systems of CFRP wrap and strips were also found to be equally effective with a total enhancement reached to about 43%.…”

“…Up to date, the behavior of RC deep beams strengthened with CFRP composites has received little consideration in the literature and the experimental investigations conducted have been found to be very limited (Zhang et al, 2004, Islam et al, 2005, Lee et al, 2011. Therefore, further experimental investigations are still needed to evaluate the performance of the strengthened deep beams under various strengthening schemes, and hence better understanding of shear and flexural resistance mechanisms associated with the use of CFRP systems could be achieved (NCHRP Report 678, 2011).…”

“…Extensive studies carried out over the past two decades on RC beams ACCEPTED MANUSCRIPT A C C E P T E D M A N U S C R I P T shear-strengthened with EB FRP (Bousselham and Chaallal, 2004, 2006a, b, 2008Carolin and Taljsten, 2005a;Islam et al, 2005;Khalifa et al, 1998;Nanni, 2000, 2002;Leung et al, 2007;Matthys, 2000;Monti and Liotta, 2007;Pellegrino and Modena, 2002Taljsten, 2003;Triantafillou, 1998) have led to many design models (Carolin and Taljsten, 2005b;Chaallal et al, 1998;Chajes et al, 1995;Chen and Teng, 2003a, b;Khalifa et al, 1998;Mofidi and Chaallal, 2011;Monti and Liotta, 2007;Pellegrino and Modena, 2002Taljsten, 2003;Triantafillou, 1998;Triantafillou and Antonopoulos, 2000;Ye et al, 2005), some of which have been adopted in design guidelines (ACI-440.2R, 2008;CNR-DT-200R1, 2013;Concrete-Society, 2012;fib, 2001;GB50608-2010GB50608- , 2010HB305, 2008;JSCE, 2001). The majority of these existing design models have assumed that the shear capacity of the EB FRP shear-strengthened beam (V u ) is a sum of the shear contributions of concrete (V c ), steel shear reinforcements (V s ) and shear strengthening FRP (V f ) based on simple superposition (i.e.…”

“…Many effective shear strengthening procedures [1][2][3][4][5] by externally bonding steel plates or high strength non-metallic fiber laminates to concrete surfaces were developed. However, few drawbacks were also identified in the bonded type strengthening technique [6][7] , such as debonding of external laminates from concrete surface due to interface shear stress concentration at the laminate end, and the long term behavior of the system owing to different coefficients of thermal expansion of concrete, adhesive, and non-metallic fiber laminates.…”
