title = "Cyclic behavior of precast segmental concrete bridge columns with high performance steel rebar as energy dissipation bars",
abstract = "The cyclic behavior of precast segmental concrete bridge columns with high performance (HP) steel rebar and that with conventional steel rebar as energy dissipation (ED) bars were investigated. The HP steel rebar is characterized by higher strength, greater ductility and superior corrosion resistance compared to the conventional steel rebar. Three large-scale columns were tested. One was designed with the HP ED bars and two with the conventional ED bars. The HP ED bars were fully bonded to the concrete. The conventional ED bars were fully bonded to the concrete for one column while unbonded for a length to delay fracture of the bars and to increase energy dissipation for the other column. Test results showed that the column with the HP ED bars had greater drift capacity, higher lateral strength and larger energy dissipation than that with fully-bonded conventional ED bars. The column with unbonded conventional ED bars achieved the same drift capacity and similar energy dissipation as that with the HP ED bars. All three columns showed good self-centering capability with residual drifts not greater than 0.4\% drift.",
