| Abstract: | Based on the determination of stress strain model of FRP confined concrete,a kind of simplified integral method is applied to calculate the complete curve of load deformation of FRP confined beam columns.The influence of several parameters,such as the strength of FRP composite,the concrete,the FRP ratio as well as slenderness ratio on the behavior and bearing capacity of the beam columns are analyzed. |

| Keywords: | FRP composite confined concrete beam column mechanical behavior bearing capacity complete curves |
