Irregular　hexagonal　concrete-filled　steel　tubes　(HCFST)　are　suitable　for　corner　columns　in　high-rise　buildings.　In　this　paper,　thirteen　slender　HCFST　columns　were　tested　under　axial　or　eccentric　compression.　The　experimental　parameters　included　the　slenderness　ratio　and　load　eccentricity.　A　finite　element　model　was　then　developed　to　simulate　such　HCFST　columns　under　compression.　After　validating　the　finite　element　model　against　experimental　results,　a　comprehensive　parametric　analysis　was　carried　out　to　generate　a　numerical　database　for　HCFST　corner　columns　to　cover　a　wide　range　of　parameters.　Concrete　strength　enhancement　from　confinement　was　observed　before　and　after　the　peak　load.　In　an　HCFST　column,　the　interaction　between　the　hexagonal　tube　and　core　concrete　is　mainly　developed　near　the　corners　of　the　steel　tube.　A　stronger　interaction　is　found　at　the　right-angle　corners　than　at　other　corners.　Equations　were　then　proposed　to　predict　the　load-carrying　capacities　of　HCFST　corner　columns　under　eccentric　compression.　Compared　with　the　test　and　numerical　results,　the　predictions　from　the　design　equations　are　generally　on　the　safe　side.　©　2022　Elsevier　Ltd
