This study presents an extended finite element (FE) model based on concrete damage-plasticity approach for fiber-reinforced polymer (FRP)-confined normal-strength and high-strength concrete (NSC and HSC). The proposed model is based on Lubliner’s model and it accurately incorporates the effects of confinement level, concrete strength, and nonlinear dilation behavior. Failure surface and flow rule were established using an up-to-date database. In order to validate the extended damage-plasticity model, finite element (FE) model is developed for specimens under a wide range of confining pressures. The results indicate that the model predictions of FRP-confined NSC and HSC are in good agreement with the experimental results.
