Using finite element analysis software ABAQUS, the nonlinear finite element calculation model of FRP confined reinforced concrete column under axial compression is estab-lished by means of modeling setting, constitutive relation selec-tion, element type determination, interface processing and net division. The bearing capacity of specimens is obtained in each stage, the conclusions comparing with the test result show that the finite element calculation conclusions of ultimate bearing ca-pacity and load -deflection curves agree well with the test re-sults, the applicability of the analysis model is verified.
