“…An increase in energy dissipation due to FRP wrapping means an increase of ductility and thus increased sectional curvature capacity and inter-storey drift capacity , Gu et al 2010, Goksu et al 2012, Pantelides and Moran 2013, Parvin and Brighton 2014, because the drift capacity of columns is dominated by the plastic hinge length and the section curvature (Ozbakkaloglu and Saatcioglu 2007, Gu et al 2010, Parvin and Brighton 2014. FRP wrapping can also prevent buckling of longitudinal reinforcement, and reducing the damage in non-seismically designed RC columns , Gu et al 2010, Goksu et al 2012,Pantelides and Moran 2013, Parvin and Brighton 2014.…”

Many concrete structures are vulnerable to extreme loadings such as accidental impact, terrorist attack and earthquake disasters. Retrofitting of existing concrete structures for enhanced performance under these loadings has been an important topic of research for a long time, especially since the 911 terrorist attack. Among the different retrofitting techniques, external bonding of fibre reinforced polymer (FRP) composites has been a popular one. This paper presents a brief review of recent research on FRP strengthened concrete structures under blast, impact, earthquake and cyclic loading.

“…Numerous studies involve the FRP retrofit of deficient reinforced concrete columns for seismic loads [39][40][41][42][43][44][45][46][47][48][49]. The effects of the FRP reinforcement length on the plastic hinge region and the drift capacity of FRP-retrofitted columns has been investigated [39].…”

“…A cyclic stress-strain model was proposed to predict the behavior of LRS FRP-jacketed RC columns under seismic loading [47]. In an analytical investigation, a design method was developed to determine the necessary FRP jacket thickness in upgrading slender RC columns to reach the target displacement ductility [48]. In an experimental study the applicability and anchorage of carbon FRP precured laminates and rods for flexural seismic strengthening of columns with low strength concrete were examined.…”

FRP Composites Strengthening of Concrete Columns under Various Loading Conditions

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.
