Combining　the　design　concept　of　the　seismic　resilience　with　precast　bridge　technology,　a　numerical　model　using　OpenSees　software　was　developed　in　this　study　to　simulate　the　seismic　performance　of　precast　self-centering　bridge　columns.　The　proposed　numerical　model　of　precast　self-centering　bridge　columns　was　validated　throguh　the　quasi-static　test　data.　Parametric　studies　were　performed　in　terms　of　aspect　ratio,　the　areas　and　initial　tensioning　force　of　axial　post-tensioned　steel　strands.　It　is　concluded　that,　with　the　increase　of　aspect　ratio　of　the　precast　self-centering　bridge　columns,　the　initial　stiffness,　post-yield　stiffness,　lateral　strength　and　energy　dissipation　capacity　decreased.　As　initial　tensionforce　increased,　the　yield　strength　increased,　while　the　effect　on　the　post-yield　stiffness　was　negligible.　The　area　of　post-tensioned　steel　strands　imposed　marginal　effect　on　the　yield　strength,　but　significant　effect　on　the　post-yield　stiffness　with　an　approximate　positive　correlation.　©　2022,　The　Editorial　Board　of　Journal　of　Basic　Science　and　Engineering.　All　right　reserved.
