“…Fibre-reinforced polymer materials are used in the reinforcement and the repair of structures, and many independent studies have shown that these materials are impermeable to oxygen. These applications have been effective in the repair of corrosion damage since the mid1990s (Alampalli, 2001;Pantazopoulou et al, 2001;Debaiky, Green, and Hope, 2002;Sen, 2003;Wang and Shih, 2004;Badawi and Soudki, 2005;Suh et al, 2007Suh et al, , 2008Winters et al, 2008). Various studies have also shown that fibre-reinforced polymer materials do not prevent corrosion entirely, but reduce the corrosion rate considerably (Baiyasi and Harichandran, 2001;Berver et al, 2001;Wootton, Spainhour, and Yazdani, 2003;Wheat, Jirsa, and Fowler, 2005).…”

“…The FRP jacket characteristics and the repair method of columns upgraded by FRP confinement after being conditioned to accelerated electrochemical corrosion have been examined [51,52]. Bae and Belarbi [53] studied the effectiveness of CFRP sheet in protecting the RC columns from corrosion of the steel reinforcement.…”

“…The research has shown that FRP retrofit was a practical alternative to conventional methods due to its superior performance in enhancing the strength and ductility of RC columns. Performance was markedly improved by increasing the number of FRP layers and by providing sufficient anchorage for each layer [51,52]. FRP composites are very efficient as repair materials which can also decrease the rate of corrosion [52,53].…”

This paper provides a review of some of the progress in the area of fiber reinforced polymers (FRP)-strengthening of columns for several loading scenarios including impact load. The addition of FRP materials to upgrade deficiencies or to strengthen structural components can save lives by preventing collapse, reduce the damage to infrastructure, and the need for their costly replacement. The retrofit with FRP materials with desirable properties provides an excellent replacement for traditional materials, such as steel jacket, to strengthen the reinforced concrete structural members. Existing studies have shown that the use of FRP materials restore or improve the column original design strength for possible axial, shear, or flexure and in some cases allow the structure to carry more load than it was designed for. The paper further concludes that there is a need for additional research for the columns under impact loading senarios. The compiled information prepares the ground work for further evaluation of FRP-strengthening of columns that are deficient in design or are in serious need for repair due to additional load or deterioration.

“…Past experiences have shown that reinforcement corrosion reduces the beam and column capacity due to steel area losses, bond deterioration, reduction in the effective concrete area, etc. (Li & Li, 2014;Ma, Che, & Gong, 2012;Pantazopoulou, Bonacci, Sheikh, Thomas, & Hearn, 2001). Despite a large body of literature on the influence of reinforcing steel corrosion on the flexural capacity of RC columns, there are few works that have dealt with the reduction in shear capacity of RC columns due to the corrosion of stirrups (Xia, Jin, & Li, 2011).…”

In this paper, an experimental study is presented on the influence of PET warping on shear performance, such as diagonal shear cracking load, peak load, and energy dissipation of RC columns with stirrup corrosion before strengthening. The experimental program involved an electrochemical process to accelerate the migration of chlorides from an external electrolyte into the tested columns, a wetting-drying cycle process with a controlled current to speed up the corrosion of the stirrup in the tested columns, the strengthening of corroded columns with PET warping, and a pseudostatic test to determine the shear capacity of the tested beams. The shear performance of PET wrapped RC columns with different corrosion levels in stirrups, including the diagonal cracking strength, the peak strength, the ductility ratio, and the energy dissipation ability, was examined and compared.
