When　components　in　a　building　structure　are　subjected　to　a　vehicle　collision,　they　may　partly　lose　the　bearing　capacity,　which　may　trigger　progressive　collapse　of　the　entire　structure.　In　order　to　clarify　the　factors　affecting　the　residual　bearing　capacity　of　framed　columns　subjected　to　the　collision　of　a　light　weight　vehicle,　numerical　investigation　is　conducted　in　this　paper.　Three　kinds　of　square　columns,　i.　e,　reinforced　concrete　(RC)　columns　and　concrete　filled　steel　tubular　(CFST)　columns　and　steel　tubular　(ST)　columns,　are　designed,　of　which　the　nominal　axial　bearing　capacities　are　equal.　The　effects　of　four　factors,　i.e.,　the　vehicle　velocity,　impact　direction,　axial　compression　ratio　and　types　of　the　columns,　on　the　residual　axial　bearing　capacity　are　analyzed.　The　results　show　that　the　residual　axial　bearing　capacity　becomes　lower　as　the　impact　velocity　increases.　The　residual　axial　bearing　capacity　under　the　impact　along　the　direction　of　diagonal　45　degree　is　higher　than　that　under　front　impact.　The　effects　of　the　compression　ratio　on　the　residual　bearing　capacity　depend　on　the　types　of　columns.　Under　the　same　conditions,　RC　columns　are　the　most　vulnerable　to　the　vehicle　collision.　The　difference　in　residual　capacity　between　CFST　and　ST　columns　is　small　under　the　impact　of　light　weight　vehicle.　©　2018,　Engineering　Mechanics　Press.　All　right　reserved.
