000019996 520__ $$2eng$$aA new type of precast segmental concrete bridge column has been proposed for accelerated bridge construction in regions of high seismicity. The proposed column adopts unbonded post-tensioning to decrease prestress loss when subjected to large lateral displacements. An option is provided to either use partially unbonded conventional mild steel or high performance steel energy dissipation bars to increase hysteretic energy dissipation. The amount of added energy dissipation is controlled so that the column maintains self-centering capability. A new hysteretic model is developed in this research for the proposed column. With the developed model, the equivalent viscous damping of the proposed column is investigated and compared to that of conventional monolithic columns.
