摘要：

The　finite　element　(FE)　software　ANSYS　was　used　to　establish　a　FE　model　for　a　stainless　steel　welded-section　beam-column.　Based　on　the　experimental　results,　the　validity　of　the　FE　model　was　verified.　The　verified　FE　model　was　used　to　investigate　the　influence　of　residual　stress　and　initial　geometric　imperfection　on　the　overall　stability　of　components　and　employed　for　parametric　investigations　to　generate　sufficient　data　points　over　a　wider　range　of　cross-section　classes,　including　slenderness　ratios　and　load　eccentricities　combinations.　Based　on　the　obtained　FE　results,　the　calculation　method　provided　in　CECS　410-2015　was　assessed　again,　and　an　improved　calculation　method　was　proposed.　The　results　indicate　that　the　calculation　method　in　CECS　410-2015　provides　conservative　predictions　for　the　overall　stability　bearing　capacity,　and　that　the　improved　calculation　method　is　more　accurate　in　predicting　the　overall　stability　bearing　capacity　of　stainless　steel　welded　I-section　and　box-section　beam-columns.　©　2019,　Engineering　Mechanics　Press.　All　right　reserved.
