Using the finite element software ANSYS to analyze CFRP strengthened concrete columns.The columns are in axial force existence situation, many should be reinforced by longitudinal and circumferential because of insufficient capacity. Subject loading,11 root were designed, aiming layer number CFRP, location orientation eccentric distant specimens.One them is a non-reinforcement column.Under compression, bending, shearing monotonic torsion, nonlinear model was established test stressed steel bar column specimens, including tensile reinforcement, compression reinforcement stirrup, as well has been analyzed, stress changing transverse CFRP. The torque-strain curves for relationship discussed among stirrup
