The study on compressive strength of fiber reinforced polymer confined concrete was conducted in this paper. Firstly, the general confinement mechanics was revealed, in which the confinement stress-σl, the restraint stiffness-El and the ultimate confinement stress-fl were proposed. Secondly, the influences of various parameters on compressive strength were analyzed by recent related studies and numerical simulation. The numerical simulation was carried out through the total of 27 finite element models under axial compressive load which were constructed by using software-ANSYS. Finally, the compressive strength model was set up by the dimension analysis and numerical regression.
