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