The　seismic　performance　of　a　fully　fabricated　bridge　is　a　key　factor　limiting　its　application.In　this　study,a　fiber　element　model　of　a　fabricated　concrete　pier　with　grouting　sleeve-prestressed　tendon　composite　connections　was　built　and　verified.A　numerical　analysis　of　three　types　of　continuous　girder　bridges　was　conducted　with　different　piers:a　cast-in-place　reinforced　concrete　pier,a　grouting　sleeve-fabricated　pier,and　a　grouting　sleeve-prestressed　tendon　composite　fabricated　pier.Furthermore,the　seismic　performance　of　the　composite　fabricated　pier　was　investigated.The　results　show　that　the　OpenSees　fiber　element　model　can　successfully　simulate　the　hysteresis　behavior　and　failure　mode　of　the　grouted　sleeve-fabricated　pier.Under　traditional　non-near-fault　ground　motions,the　pier　top　displacements　of　the　grouting　sleeve-fabricated　pier　and　the　composite　fabricated　pier　were　less　than　those　of　the　cast-in-place　reinforced　concrete　pier.The　composite　fabricated　pier　had　a　good　self-centering　capability.In　addition,the　plastic　hinge　zones　of　the　grouting　sleeve-fabricated　pier　and　the　composite　fabricated　pier　shifted　to　the　joint　seam　and　upper　edge　of　the　grouting　sleeve,respectively.The　composite　fabricated　pier　with　optimal　design　parameters　has　good　seismic　performance　and　can　be　applied　in　high-intensity　seismic　areas;however,the　influence　of　pile-soil　interaction　on　its　seismic　performance　should　not　be　ignored.
