An approach is presented for displacement-based analysis of reinforced concrete columns based on principles of axial-shear-flexure interaction. Shear behavior is modeled by applying the modified compression field theory, and flexure behavior is modeled by employing the conventional section analysis. The mechanisms of shear and flexure are coupled as springs in series, considering axial deformation interaction and concrete strength degradation, and satisfying compatibility and equilibrium relationships. The proposed approach is simplified to enable modeling a reinforced concrete column using a single section analysis with a single shear model for the entire element. The simplified approach ...
