“…Most of the available ultimate stress and strain models are only applied to the FRP confined intact concrete. There are only three existing models that were developed for FRP confined damaged concrete 12,13,15 . Wu et al 12 developed ultimate strength and strain models of FRP confined predamaged concrete column with a circular cross‐section, as given in Equation ) and Equation ).…”

“…Numerous studies of stress–strain curve, compressive strength and ultimate strain of FRP confined concrete have been conducted 6–9 . Most of these studies addressed FRP‐confined intact concrete specimens, 10,11 whereas a limited number of studies focused on the behavior of FRP confined predamaged concrete 12–20 . However, in practice, FRP jackets are usually applied to concrete columns with existing material damage and potential future damage.…”

“…They concluded that FRP effectively improved the strength and deformability of predamaged concrete. Only Ma et al 13 developed a stress–strain model for cyclically loaded FRP‐confined predamaged concrete. However, the model was developed with limited tested results with only two specimens were subjected to both predamage loading and cyclic loading.…”

Most existing studies on fiber reinforced polymer (FRP) confined concrete have focused on undamaged concrete that is subjected to uniaxial monotonic compression. However, FRP jackets are usually applied to concrete columns with existing material damage and potential future damage. This paper investigates FRP confinement on concrete with damage before and after FRP jacketing. A total of 32 FRP‐confined concrete specimens were tested under axial compression in this work. The prior damage before FRP jacketing was implemented as predamaging by applying preloading and then release on the plain concrete specimens. The post damage after FRP jacketing was performed by applying cyclic axial compression loading on FRP‐confined concrete specimens. The test results reveal that the concrete predamage levels have significant influences on the cyclic stress–strain curve and envelop stress–strain curve for FRP confined concrete under cyclic loading. Existing models on ultimate state, plastic strain, reloading and unloading moduli were evaluated and investigated in this work.
