In　this　study,　an　innovative　aluminum　alloytube-timber　composite　column　structure　is　proposed,　which　includes　the　outer　aluminum　tube,　inner　timber　and　mortar.　Axial　compressive　test　was　carried　out　on　the　proposed　stub　columns,　and　the　test　variables　included　the　tube　thickness,　timber　diameter,　water-cement　ratio　of　cement　paste,　and　the　number　of　layers　of　CFRP.Failure　modes,　load-displacement　curves,　strength,　stiffness,　ductility　and　strain　characteristics　were　analyzed.　Results　show　that　the　final　failure　modes　were　buckling　damage　in　the　middle　of　the　column　and　buckling　damage　at　the　end　of　the　column.　The　load-displacement　curve　can　be　roughly　divided　into　elastic　phase,　elastic-plastic　phase,　buckling　phase,　failure　phase,　and　secondary　rising　phase.　The　different　test　variables　have　certain　influences　on　the　compressive　behavior　of　the　stub　columns,　and　the　timber　diameter　has　the　most　influence　on　the　bearing　capacity,　stiffness,　and　ductility.　Finally,　a　calculation　method　for　the　ultimate　bearing　capacity　was　developed,　the　calculated　values　fit　well　with　the　experiment　results.　©　2022　Science　Press.　All　rights　reserved.
