The　local　compressive　performance　of　hexagonal　concrete-filled　steel　tubularHCFSTcolumns　with　right　angles　was　studied.　Local　compressive　tests　on　this　type　of　20　HCFST　columns　were　carried　out.　The　effects　of　the　end　plate　thicknesslocal　compressive　area　ratioand　steel　ratio　on　the　local　compressive　performance　of　the　HCFST　column　were　studied.　The　test　shows　that　the　local　compressive　strength　of　the　HCFST　specimen　is　proportional　to　the　thickness　of　the　end　plate　and　inversely　proportional　to　the　local　compressive　area　ratio.　The　end　plate　can　significantly　improve　the　local　compressive　strength　of　the　HCFST　specimen.　The　mechanism　analysis　based　on　the　numerical　model　shows　that　for　the　HCFST　specimen　under　local　pressurethe　load　is　mainly　taken　by　the　concrete.　The　confinement　of　the　steel　tube　is　mainly　concentrated　in　the　corner.　The　steel　tube　of　the　HCFST　specimen　without　the　end　plate　can　provide　greater　confinement.　The　shape　of　the　loading　block　has　a　great　influence　on　the　local　compressive　strength　of　the　HCFST　specimen　without　the　end　plate.　The　steel　tube　can　form　strong　confinement　on　the　core　concrete　within　the　range　of　0~1.2Bwhere　B　is　the　side　length　of　the　steel　tubefrom　the　loading　end.　The　parametric　analysis　shows　that　the　local　compressive　strength　decreases　with　the　increases　of　the　local　compressive　area　ratio　but　increases　with　the　increase　of　the　concrete　strength　or　the　thickness　of　the　end　plate.　The　steel　ratiosteel　strength　and　eccentricity　have　a　moderate　effect　on　the　local　compressive　strength.　Finallya　simplified　predicting　model　of　the　local　compressive　strength　of　the　HCFST　column　was　proposed.　©　2023　Hunan　University.　All　rights　reserved.
