Stability　tests　were　conducted　on　axially　loaded　extruded　H-section　6061-T6　aluminum　compression　members.　The　main　parameters　varied　in　the　tests　are　slenderness　ratio.　All　6　specimens　that　were　hinged　at　both　ends　and　tested　failed　by　overall　flexural　buckling　in　the　plane　of　the　major　axis.　The　measured　stability　coefficients　were　determined.　At　the　same　time,　the　performances　of　aluminum　alloy　material　used　in　test　were　surveyed,　and　the　material　property　data　were　obtained.　The　finite　element　analysis　model　was　established　and　verified　by　the　test　results.　A　series　of　parametric　analysis　was　carried　out,　and　on　the　basis　of　this　a　new　column　curve　was　proposed　by　a　nonlinear　fitting.　The　computational　column　curves　of　GB50429,　EN1999　and　the　proposal　were　compared　with　the　parametric　analysis　results　and　the　domestic　existing　test　data　at　home.　It　is　found　that　the　two　codes　are　very　close　and　both　are　too　conservative.　Meanwhile,　the　proposed　column　curve　is　in　agreement　with　the　parametric　analysis　results　and　the　experimental　results　and　are　overall　safety,　which　can　provide　useful　information　for　engineering　application　and　specification　revision　of　such　aluminium　structures.　©　2016,　Science　Press.　All　right　reserved.
