With　column　limb　slope　as　the　experimental　parameter,　compression　experiments　of　6　variable　cross-sectional　concrete　filled　steel　tubular　(CFST)　laced　columns　were　studied,　while　two　other　uniform　cross-sectional　CFST　laced　columns　for　comparative　analysis.　Stress　mechanism　and　failure　mode　of　variable　CFST　laced　columns　are　analysed.　The　influence　of　column　limb　slope　on　load　capacity　of　variable　CFST　laced　columns　is　discussed.　The　results　show　that　variable　CFST　laced　columns　are　overall　damage.　Compared　with　2　m　high　uniform　CFST　laced　column,　ultimate　load　capacity　of　variable　CFST　laced　columns　with　column　limb　slopes　1:40　and　1:20　have　a　corresponding　increase　of　3%　and　5%.
