Introduction:
Bambooisafast-growingandrenewablenaturalresourcewidelyusedforvariousapplicationssuchasconstruction,furniture,andpaperproduction.Bambooculmsarehollow,cylindricalstructureswithgoodstructuralpropertiessuchashighstiffness,strength,andelasticity.BambooculmshavebeenusedforcenturiesasbuildingmaterialsinmanyAsiancountriesduetotheiraffordabilityandsustainability.However,thestructuralbehaviorofbambooculmsundercompressionisnotwellunderstood.
Compressivestrengthisoneofthefundamentalmechanicalpropertiesofbambooculms,asitdeterminesthemaximumloadthatabambooelementcanbearwithoutfailure.Thecompressivestrengthofbambooculmscanbeaffectedbyvariousfactorssuchasthepositionandnumberofnodes,thethicknessoftheculmwall,andthemoisturecontent.Inaddition,thebearingcapacityofabambooculmcanbeenhancedbyreinforcingitwithaninner-boredbamboopile.
Supportplatformsarecommonlyusedtosupportbambooculmsduringcompressiontestingtopreventtheculmsfrombendingorbuckling.However,theeffectofsupportplatformsonthebearingcapacityofbambooculmshasnotbeenfullyinvestigated.
