Anchorage Devices Used to Improve the Performance of Reinforced Concrete Beams Retrofitted with FRP Composites: State-of-the-Art Review (2013, background): “Most experimental data highlights that almost all beams strengthened by enclosed wrapping typically fail due to FRP rupture after localized debonding (Chen and Teng 2003).”
Debonding failure along a softening FRP-to-concrete interface between two adjacent cracks in concrete members (2007, background): “Indeed, a number of failure modes in FRP-strengthened RC members are directly caused by interfacial debonding between the FRP and the concrete [4–7].”
Improved theoretical solution for interfacial stresses in concrete beams strengthened with FRP plate (2006, background): “…stresses through the thickness of adhesive rNi ði ¼ 1; 2Þ longitudinal normal stresses for adherend ‘‘i’’ 1997, 2002; Malek et al., 1998; Saadatmanesh and Malek, 1998; Spadea et al., 1998; Triantafillou and Antonopoulos, 2000; Chen and Teng, 2001, 2003; Bakis et al., 2002; Smith and Teng, 2002a,b).”
Full-range behavior of FRP-to-concrete bonded joints (2004, background): “In RC beams shearstrengthened with FRP plates/sheets bonded to the sides, IC debonding can arise as a result of a shear crack [8].”
On the finite element modelling of RC beams shear-strengthened with FRP (2012, background): “A significant number of existing studies have been concerned with the shear strengthening of RC beams with externally bonded FRP reinforcement in the forms of strips, plates or sheets [5-9].”
Experimental study on FRP-to-concrete bonded joints (2005, methodology): “In debonding failures in FRP shear-strengthened RC beams with transverse plates, the bond strength model developed from pull tests is directly applicable [39].”
Unified Analytical Approaches for Determining Shear Bond Characteristics of FRP-Concrete Interfaces through Pullout Tests (2006, background): “…have shown quantitatively how the interface bond strength or local bond stress-slip property influences peak flexural or shear strength of RC members retrofitted with FRP externally (Khalifa et al. 1998, Kamiharako et al. 2001, Yokota 2002, Chen and Teng 2003, Teng et al. 2003, Wu and Yin 2003).”
FRP-to-concrete interfaces between two adjacent cracks: Theoretical model for debonding failure (2006, background): “IC debonding can also arise as a result of a shear crack in RC beams shear-strengthened with FRP (Chen and Teng, 2003).”
