Rousakis et al.(2007) also presented an analytical stress-plastic strain model as a strain-hardening-softening Drucker–Prager constitutive model for the assessment and calibration of the elastoplastic behaviour of FRP-confined concrete,involving evaluation of permanent deformations from observed experimental deformations and theoretical elastic response of confined concrete.The satisfactory predictive ability of the model is verified through comparisons to numerous published experimental data and analytical models.
