In this study, the experimental program of 8 square New RC columns under concentric loading was carried out. The nominal compressive strength of the concrete is 70 MPa. The yielding strength for longitudinal reinforcement is 690 MPa. For transverse reinforcement, the cross-sectional area should be provided by ACI 318-14, and the yielding strength is between 420 MPa and 790 MPa to compare the differences in the confinement effect of the core concrete on the strength of different transverse reinforcements. From experimental result, it is expected to propose a local-based stress-strain model for confined high strength concrete. Furthermore, this study presents the seismic evaluation of columns based on the proposed stress and strain model for confined concrete used in New RC column. The load and displacement relationship of New RC columns with flexural failure mode can be analyzed by conducting the moment-curvature analysis with XTRACT first, and followed by the integration process of moment-area method, as well as the contribution of plastic hinge length, to obtain the element behavior from elastic to inelastic state.
