| Abstract: | Inelastic incremental stiffness equations of tapered elements are established by employing the model of modified elastic?plastic hinges and the concept of tangent modulus,based on the developed elastic stiffness for the Timoshenko?Euler tapered elements.Planar inelastic stability of tapered columns,axially and eccentrically loaded,are studied with the proposed equations respectively.Column curves and thrust?moment interaction curves of tapered columns with various tapered ratios are presented. |

| Keywords: | tapered columns inelastic stiffness column curves interaction curves |
