Experimental and theoretical issues in FRP-concrete bonding

Analytical model to predict the lifetime of concrete members externally reinforced with FRP

“…[2,3,5,13,[21][22][23]26,28,43,47,49], brings out the fact that, in a carbonated concrete, the ranges of variation of K IIC , v c , and N are reasonably narrow. In fact, these parameters depend mainly on the depth of carbonation and the strength of concrete.…”

“…There are many models in the literature to calculate the s b distribution and their maximum, which is herein denoted by s bM [2][3][4]6,9,[11][12][13][14][15][16][17][18][19][20][21].…”

“…Review of current scientific literature shows that extensive research has been published on debonding failure mode. The studies date back to the '60, although the real surge began in the '90 with the introduction of FRP [1][2][3][4][5][6][7][8][9][10][11].…”

Deflection of reinforced concrete beams strengthened with CFRP

“…It is well known that the bond between concrete and CFRP is not stiff and due to shear strains external reinforcement may slip (Chen, Pan 2006;Pham, Al-Mahaidi 2007;Perera et al 2004;Ueda, Jianguo 2005;Camli, Binici 2007;Lu et al 2006;Casas, Pascual 2007;Schilde, Seim 2007;Iovinella et al 2013;Ferracuti et al 2007;Subramaniam et al 2007;Mostofinejad, Shameli 2013;Wang et al 2007;Freddi, Savoia 2008;Biolzi et al 2013;Yuan et al 2004;Ramos et al 2004;Dai et al 2005;Ramos et al 2006;Pan, Leung 2007a;Saxena et al 2008;Niu, Wu 2006;Pham et al 2006;Pan, Leung 2007b;Ferrier et al 2006;Mazzotti et al 2008). So the deflection of the strengthened structure increases and the effect of strengthening decreases.…”
