Experiments on precast bridge piers with bonded prestressing tendons and continuous mild reinforcement are conducted. Continuous longitudinal reinforcing bars significantly improves seismic performance of the precast pier. The prestressed precast columns show stable behavior up to drift level of 8%. Magnitude of effective prestressing force is an essential design consideration to prevent fracture of tendons.
