摘要：

Based on the analysis of more than two hundred specimens of concrete cylinders confined with FRP, a method for predicting the ultimate strength of FRP-confined concrete is presented. First, the calculation of the Poisson's ratio of concrete confined with a sufficient amount of FRP is suggested. Then, according to strain compatibility, the ultimate strain of FRP-confined concrete is predicted. Finally, a tri-linear model is suggested to predict the stress-strain response of FRP-confined concrete cylinders. Through comparison with existing experimental data of other researchers, the effectiveness of the proposed model is verified.
