“…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.…”
