Study on Compressive Strength of Fiber Reinforced Polymer Confined Concrete

摘要

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-σ_1, the restraint stiffness-E_1 and the ultimate confinement stress-f_1 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.
