ABSTRACT
The prestressed column, where unbonded posttensioned tendons are arranged along the axis of the RC column, showed self-centering behavior after lateral loading. To investigate the detailed hysteretic response, nine prestressed RC columns with different axial loads and transverse reinforcement arrangements were tested and subjected to the combined action of cyclic horizontal loading and constant axial loading. The experimental results revealed the failure modes, and the drift capacity was analyzed using the ductility and plastic hinge zone length. The controlling effects on residual displacements varied over time during testing, and their mechanism was explained from the point of view of energy dissipation capacity.
