“…The behavior of FRP-wrapped columns has been investigated for freeze thaw exposure, repair of corroding reinforced concrete columns, and fire resistance. The FRP-wrapped columns demonstrated adequate performance under these severe conditions [50]. The FRP jacketing provides an alternative to conventional repair methods for corrosion-damaged reinforced concrete columns.…”

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.

“…This is due to their high strength-to-weight and stiffness-to-weight ratios, high corrosion resistance, good fatigue behaviour, and their ability to be formed and shaped to the existing structure [13]. Research has demonstrated that for a compression member, the use of circumferential wrapping of FRP wrapping can result in an increase in strength and ductility [14][15][16]. Consequently, RC members with low quality concrete and/or inadequate confinement reinforcement can be wrapped with CFRP composite sheets for highly improved behaviour.…”

“…Kodur et al, has conducted several studies on the effects of fiber reinforcement, fly ash, and tie configuration on the fire performance of high-strength concrete (HSC) columns [9][10][11][12]. There have also been a significant number of studies conducted on fiber reinforced polymer (FRP) confined concrete columns, including those conducted by Green et al [13], Chowdury et al [14], Cree et al [15], Gefu et al [16], Bisby et al [17] and Kodur et al [18] to name a few.…”

“…Five additional type K thermocouples owned by the fire testing facility were used to record the furnace temperature as well as the ambient temperature of the laboratory. Because FRP materials are vulnerable to extreme temperatures [13][14][15][16][17]20], the Tyfo ® CFP System [36] was applied to the surface of the two CFFT columns. The Tyfo ® CFP System is a three part, low profile system with the ability to provide up to a 4 h fire protection rating for square and circular columns per American Society for Testing and Materials (ASTM) E119, and a Class 1 flame and smoke rating per ASTM E84.…”

Abstract:The fire performance of protected concrete-filled fiber reinforced polymer (FRP) tube (CFFT) and conventional reinforced concrete (RC) bridge columns is studied through two phases of experimental research comprised of fire exposure and residual axial capacity tests. Two one-fifth scale CFFT columns and two one-fifth scale conventional RC columns having similar axial and flexural capacities were subjected to two durations of extreme temperature exposure. The CFFT columns were protected by the Tyfo ® CFP fire protection system during the experiments. Subsequently, the post-fire robustness of the columns was quantified by measuring the residual axial capacity characteristics of each column. The protected CFFT columns exhibited superior axial strength and stiffness retention compared to the RC columns after fire exposure.
