A　new　composite　structure,　concrete　filled　steel　tubular　(CFST)　beam　with　corrugated　steel　web,　was　presented.　Experiments　of　three　beams　were　carried　out.　Stresses,　displacements,　failure　modes　and　ultimate　carrying　capacity　of　the　beams　were　analyzed　and　compared　with　each　other,　as　well　as　CFST　truss　beam.　Experimental　results　show　that　joint　failure　in　CFST　truss　beam　can　be　avoided　by　substituting　web　tubular　members　with　corrugated　steel　web,　and　the　flexible　rigidity　and　ultimate　load-carrying　capacity　is　improved　considerably.　Filling　concrete　into　the　steel　tube　will　lead　to　higher　load　carrying　capacity.　However,　this　improvement　is　more　evident　in　upper　chord　than　that　in　bottom　chord.　The　Quasi-Plane-Section　method　can　be　used　in　calculation　of　load　carrying　capacity　of　CFST　beam　with　corrugated　steel　web.
