The behavior of short-term axially preloaded concrete columns with FRP confinement under axial loading is simulated using finite element method, and the computing results are compared with the test ones.The comparisons show that proper analysis model can accurately simulate the axial compressive property of FRPconfined concrete columns. Then a parameter analysis is carried out to investigate the impact of longitudinal reinforcement ratio, volumetric lateral reinforcement ratio, concrete strength and restrain stiffness of FRP on the bearing capacity of columns and the load-strain curve under different preloading stress levels.
