Oxygen Permeability of FRP-Concrete Repair Systems
- Abstract: Chandra Khoe, Rajan Sen, and Venkat R. Bhethanabotla Fiber reinforced polymers (FRP) are increasingly used for repairing corrosion-damaged concrete structures. The performance of the repairs is critically dependent on the oxygen permeability of the FRP-concrete system. This paper presents the results of an experimental study in which the oxygen permea ...

On Factors Affecting the Ultimate Condition of FRP Wrapped Concrete Columns
- Abstract: J. F. Chen, S. Q. Li, and L. A. Bisby FRP wrapped circular concrete columns under axial compression usually fail due to FRP rupture in the hoop direction. The average measured hoop strain in the FRP jacket at failure of such columns, i.e. the apparent FRP rupture strain, is typically considerably lower than the ultimate tensile strain o ...

Shear Strength Model for FRP-Strengthened RC Beams with Adverse FRP-Steel Interaction
- Abstract: G. M. Chen, J. G. Teng, and J. F. Chen RC beams shear-strengthened with externally-bonded FRP U-strips or side strips usually fail due to debonding of the bonded FRP shear reinforcement. Because such debonding usually occurs in a brittle manner at relatively small shear crack widths, some of the internal steel stirrups intersected by the ...
