In　this　paper,　a　new　type　of　concrete-filled　Glass　Fiber　Reinforced　Polymer　(GFRP)　tubular　hollow　composite　column　is　tested　and　analyzed　by　finite　element　analysis.　The　axial　pressure　test　of　27　concrete-filled　GFRP　tubular　hollow　composite　columns　is　made　to　investigate　the　compressive　properties　of　the　specimens,　including　the　failure　mode,　ultimate　bearing　capacity　under　axial　compression,　load-strain　relationship　and　load-displacement　relationship.　The　effects　of　the　three　parameters　of　hollow　ratio,　diameter-to-thickness　ratio　of　GFRP　tube　and　concrete　strength　grade　on　the　axial　compressive　properties　of　concrete-filled　GFRP　tubular　hollow　composite　columns　are　studied,　and　some　key　principles　of　designing　concrete-filled　GFRP　tubular　hollow　composite　columns　are　presented.　The　parameters　of　hollow　ratio,　diameter-to-thickness　ratio　of　GFRP　tube,　and　concrete　strength　grade　are　analyzed　by　using　the　verified　finite　element　model.　An　ultimate　bearing　capacity　adjustment　coefficient　is　proposed,　which　takes　into　consideration　the　influence　of　hollow　sections.　A　recommended　formula　is　given　for　the　axial　bearing　capacity　of　concrete-filled　GFRP　tubular　hollow　composite　columns.　©　2020　Elsevier　Ltd
