摘要

To maintain consistency with carbon steel design guidance, the current European design codernfor stainless steel structures EN 1993-1-4 employs many of the relevant design expressions from the equivalentrncarbon steel design code EN 1993-1-1. While this is generally satisfactory, there are a number of instances inrnwhich overly conservative designs result. Given the high initial material cost of stainless steel, the derivation ofrnmore economic design expressions in accordance with the actual material response is warranted. To this end,rnthe Continuous Strength Method (CSM) has been developed and verified against experimental and numericalrnresults.To date, the scope of theCSMhas been restricted to stainless steel cross-sections subjected to compressionrnor uniaxial bending. The present paper aims to extend the scope of application of the CSM to cross-sectionsrnsubjected to more general loading conditions likely to occur in practice. Furthermore, a simplified version ofrnthe CSM, with a more straightforward base curve and material model, but still capturing the essential strainrnhardening features of stainless steel, is considered. The comparisons show that the simplifications lead to veryrnlittle loss of accuracy and will be developed further in future studies.
