N2 - A study on finite element (FE) modelingof fiber-reinforced polymer (FRP)-confined normal-strength and high-strength concrete (NSC and HSC) based on an extended concrete damage-plasticity approach is presented. The study focuses on the extension ofLubliner's model by accurately incorporating the effects of confinement level, concrete strength, and nonlinear dilation behavior of FRP-confined concrete. Failure surface and flow rule were established using an up-to-date database. In order to validate the extended damage-plasticity model, the predictions of the FE modeling are compared with the experimental results. These comparisons indicate that the extended approach accurately predicts the compressive behavior of FRP-confined NSC and HSC.
