Obtaining　a　larger　moment　of　inertia　and　overall　stability　with　smaller　material　input,　which　is　an　effective　way　to　improve　the　bearing　capacity　and　reduce　the　self-weight　of　structural　columns.　This　paper　proposes　a　crosssection　corrugated　plate　steel　special-shaped　column　(CCSC),　which　is　based　on　the　optimization　design　idea　of　steel　profiled-shaped　column　section,　combined　with　the　comprehensive　consideration　of　the　overall　stability　of　steel　structure　column　members,　material　use　efficiency　and　building　interior　space　utilization　rate.　The　new　CCSC　is　composed　of　three　parts:　core　square　steel　pipe,　corrugated　plate,　and　flange　plate.　The　high-out-of-plane　stiffness　characteristic　of　corrugated　plate　is　utilized　to　improve　the　section　rotation　radius.　The　three　parts　above　are　coordinated　to　resist　lateral　load.　The　square　steel　pipe　and　flange　plate　are　the　main　vertical　bearing　plates.　The　new　special-shaped　column　can　obtain　a　larger　moment　of　inertia　and　overall　stability　with　a　smaller　material　input,　thus　improving　the　bearing　capacity.　Through　the　combination　of　theoretical　analysis　and　numerical　simulation,　the　overall　stability　of　the　axial　compression　of　CCSC　are　analyzed,　and　the　instability　modes　and　failure　modes　of　CCSC　are　revealed.　The　design　method　and　suggestions　for　the　stability　of　CCSC　under　axial　compression　are　put　forward.　Then,　the　overall　stability　design　and　application　suggestion　based　on　conventional　square　steel　tube　is　given.　The　results　show　that　the　stability　design　method　of　CCSC　under　axial　compression　can　effectively　judge　the　instability　mode　of　CCSC　and　obtain　the　ultimate　bearing　capacity　of　the　whole　member.　Compared　with　square　steel　tube　columns　with　regularized　slenderness　ratio　greater　than　0.8　in　structural　design,　the　CCSC　has　obvious　advantages　in　overall　stability　and　steel　consumption.
