Precast　segmental　columns　have　attracted　wide　attentions　in　bridge　construction　industry　recently　due　to　its　ability　to　accelerate　construction　speed,　improve　construction　quality　and　reduce　environmental　impact.　It　is　of　great　practical　importance　to　study　the　seismic　performances　of　segmental　columns,　and　many　experimental　and　numerical　studies　have　been　performed.　However,　most　previous　studies　focused　on　segmental　column　itself,　the　research　on　the　seismic　performance　of　a　whole　bridge　structure　supported　by　precast　segmental　columns　is　very　limited.　In　particular,　no　systematic　studies　have　been　performed　to　investigate　the　seismic　performances　of　segmental　columns-supported　bridges　subjected　to　near-fault　(N-F)　ground　motions　(GMs).　To　bridge　this　research　gap,　the　seismic　responses　of　three　bridge　structures　(i.e.　a　segmental　columns-supported　bridge,　a　bridge　supported　by　segmental　columns　with　internal　energy　dissipation　bars,　and　a　conventional　bridge　supported　by　monolithic　columns)　subjected　to　four　types　of　earthquake　ground　motions　(i.e.　a　N-F　GM　with　fling-step　(F-S)　effect,　a　N-F　GM　with　forward-directivity　(F-D)　effect,　a　non-pulse-like　N-F　GM,　and　a　typical　far-field　(F-F)　GM　are　investigated　and　compared　in　the　present　study　based　on　the　validated　numerical　models　developed　in　ABAQUS.　The　influences　of　permanent　ground　displacement　in　the　F-S　ground　motion　and　pulse　period　are　also　systematically　investigated.　The　numerical　results　demonstrate　that　the　permanent　ground　displacement　in　the　N-F　ground　motions　has　very　different　effects　on　the　segmental-columns　supported　bridge　and　monolithic　columns　supported　bridge.　©　The　Author(s)　2022.
