In　order　to　investigate　static　loading　capacity　of　stainless　steel　welded　I-section　beam-columns,　20　stainless　steel　beam-columns,　including　ten　austenitic　(five　were　designed　for　buckling　around　major　axis　and　five　around　minor　axis)　and　ten　duplex　(five　were　designed　for　buckling　around　major　axis　and　five　around　minor　axis)　stainless　steel　welded　I-section　specimens　were　designed.　Slenderness　ratios　of　specimens　varied　from　50　to　120　and　design　loading　eccentricities　were　50,　60　mm　and　70　mm.　The　initial　crookedness　and　loading　eccentricities　were　measured　prior　to　column　tests　in　order　to　improve　accuracy.　According　to　test　results,　failure　modes,　load-displacement　curves,　load-strain　curves　and　loading　capacities　were　analyzed,　and　the　test　results　were　compared　with　predictions　of　current　specifications　CECS　410:2015　and　EN　1993-1-　4.　The　results　indicate　that　all　members　fail　in　the　form　of　overall　flexural　buckling　without　evident　local　buckling.　The　bearing　capacity　decreases　with　increase　of　slenderness　ratio　and　loading　eccentricity.　For　the　stainless　steel　welded　I-section　beam-columns,　both　EN　1993-1-　4　and　CECS　410:2015　provide　conservative　predictions　for　the　load　capacity.　©　2018,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
