Seismic　capacity,　including　the　ultimate　load-carrying　capacity　and　ultimate　deformation　capacity　of　precast　segmental　concrete　double-column　(PSCDC)　piers　with　steel　sleeve　(SS)　connection　or　grouted　corrugated-metal　duct　(GCMD)　connection,　has　been　verified　to　be　similar　to　those　of　cast-in-place　(CIP)　piers　by　quasi-static　tests.　However,　the　lack　of　knowledge　of　seismic　response　characteristics　and　damage　process　of　PSCDC　piers　has　limited　their　application　in　high-intensity　seismic　areas.　Therefore,　shake　table　tests,　using　variable　types　and　intensities　of　seismic　ground　motions,　were　performed　to　investigate　the　seismic　behavior　of　connection　joints　and　to　evaluate　the　seismic　performance　of　PSCDC　piers　with　SS　and　GCMD　connections.　Also,　a　finite　element　analysis　(FEA)　model　was　developed　to　study　the　influence　of　design　parameters　on　the　seismic　behavior　of　the　piers.　The　results　showed　that　the　main　damage　in　PSCDC　piers　was　caused　by　the　cyclic　opening　and　closing　of　connection　joints.　Under　high-intensity　ground　motions,　the　PSCDC　piers　had　a　lower　seismic　performance　than　the　CIP　piers　due　to　a　significant　decrease　of　their　integrity　and　stiffness.　The　seismic　performance　of　PSCDC　piers　is　comparable　to　CIP　piers　when　using　an　appropriate　initial　stress　of　the　prestressing　tendons.
