To　improve　the　seismic　performance　and　construction　convenience　of　prestressed　precast　segmental　column,　a　bottom　core-filled　multi-segmental　precast　hollow　column　was　developed　and　its　seismic　performance　was　investigated.　Firstly,　the　core　height　design　method　of　the　new　precast　segmental　column　was　proposed.　Then,　a　scaled　model　of　precast　segmental　column　with　core　filling　at　bottom　segments　was　designed　and　a　quasi-static　test　of　the　column　was　conducted.　Based　on　the　experimental　results,　concrete　crack　development,　failure　mode,　hysteresis　performance,　ductility,　energy　dissipation,　and　the　openings　of　the　joint　of　the　new　precast　column　were　analyzed.　The　results　show　that　the　failure　mode　of　the　developed　bottom　core-filled　multi-segmental　precast　segmental　column　was　concrete　crushing　in　the　bottom　segment,　but　the　range　was　small.　It　indicated　that　the　proposed　design　method　of　the　new　precast　column　is　feasible,　and　the　expected　failure　mode　can　be　realized.　The　new　column　has　good　self-resetting　capacity,　energy　consumption　capacity　and　ductility　performance,　it　indicated　that　the　column　has　excellent　seismic　performance.　©　2024　Science　Press.　All　rights　reserved.
