In　order　to　investigate　the　loading　capacity　of　fillet-weld　connections　fabricated　from　duplex　stainless　steel　grade　S22053,　material　tests　were　conducted　on　round　bar　specimen　made　from　the　base　material　and　the　corresponding　weld　metal.　Tensile　tests　were　conducted　on　transverse　fillet-weld　connections　and　longitudinal　fillet-weld　connections,　the　ultimate　load　capacity　of　the　welded　connections　were　tested,　and　the　deformation　developments　with　the　load　increment　was　measured　as　well.　The　nonlinear　finite　element　analysis　of　the　stainless　steel-weld　connections　subjected　to　uniaxial　tensile　forces　were　performed　by　finite　element　software　ANSYS,　and　the　computational　results　were　compared　with　test　data.　The　comparison　indicated　that　the　finite　element　model　using　the　true　stress-stain　curves　and　considering　the　differences　of　constitutive　relationship　between　base　metal　and　weld　metal　could　simulate　the　uniaxial　tensile　tests　effectively.　Finally,　parametric　analysis　was　carried　out　on　parameters　which　could　influence　the　bearing　behavior　of　stainless　steel-weld　connections,　and　the　simulation　results　were　compared　with　the　design　value　calculated　according　to　European　steel　structures　(Eurocode　3),　American　stainless　steel　code　(SEI/ASCE　8-02),　and　Technical　specification　for　stainless　steel　structures　(CECS　410:2015)　respectively.　The　ratios　of　simulated　value　to　design　value　were　obtained,　so　as　to　provide　a　reference　for　the　improvement　and　engineering　application　of　stainless　steel　design　code.　©　2017,　Engineering　Mechanics　Press.　All　right　reserved.
