This　article　reports　the　experimental　behavior　of　square　hollow　stainless　steel　tubular　trusses　under　static　loading.　A　total　of　five　specimens,　including　three　trusses　with　K-joint,　one　truss　with　N-joint,　and　one　truss　with　T-joint,　were　tested　to　study　the　effect　of　different　outer　widths　of　brace　members　and　the　types　of　joint　on　the　flexural　performance　of　square　hollow　stainless　steel　tubular　trusses.　The　failure　modes,　flexural　rigidity,　load　carrying　capacity,　ductility,　load　versus　displacement　curves,　and　load　versus　strain　curves　of　all　the　tested　specimens　are　presented.　It　can　be　seen　that　the　chords　of　all　specimens　experienced　surface　plasticity.　The　test　results　indicate　that　the　specimen　with　T-joint　has　the　best　ductility.　The　flexural　rigidity　of　the　truss　with　the　K-joint　is　better　than　that　of　specimens　with　N-joint　or　T-joint.　The　flexural　rigidity　of　trusses　with　the　K-joint　was　found　to　increase　with　the　increase　of　outer　width　(D)　of　the　brace　members　varying　from　38　to　80　mm.　Besides,　the　load-carrying　capacity　per　unit　weight　of　the　specimen　with　T-joint　is　better　than　that　of　specimens　with　N-joint　or　K-joint.　©　2021　Wenyuan　Kong　et　al.,　published　by　De　Gruyter　2021.
