To minimize residual displacements in reinforced concrete bridge columns, a new method is proposed whereby longitudinal prestressing strands replace some of the typical longitudinal mild reinforcing bars. The seismic performance of such columns with prestressing strands is investigated through a series of quasi-static analyses and dynamic analyses.
