Cross-section classification is one of the key concepts in the design of metallic structures.
The reliability of the proposed cross-section classification limits was verified by means of the EN 1990 — Annex D method.
In this method, cross-section classification is replaced by a normalized deformation capacity, which defines the maximum strain that a cross-section can endure prior to failure.
The proposed method does not follow the traditional cross-section classification approach, which primarily relies on the assumption of a bilinear, elastic perfectly-plastic matelastic perfectly-plastic
A revised buckling curve for stainless steel in fire, consistent strain limits and a new approach to cross-section classification and the treatment of local buckling are proposed.
We present a computational procedure for evaluating the collapse load and assessing the cross-section classification of thin-walled sections of arbitrary shape on the basis of Eurocode prescriptions.
In current structural stainless steel design codes, local buckling is accounted for through a cross-section classification framework, which is based on an elastic, perfectly-plastic material model, providing consistency with the corresponding treatment of carbon steel cross-sections.
The findings have been employed to derive slenderness parameters in a system of cross-section classification for elliptical hollow sections, and form the basis for the development of effective section properties for slender elliptical tubes.
The experimental results combined with the obtained numerical results were used to assess the suitability of the current European (EN 1993-1-1 and EN 1993-1-12) classificationclimitsication limits for HSS structural components.
Necessarily, the method must also include the variation of mechanical strains through the web depth, in order that the limiting depth to thickness ratio that delineates yielding and elastic buckling (and hence the cross-section classification) can be prescribed.
Cross-section classification is an important concept in the design of metallic structures, as it addresses the susceptibility of a cross-section to local buckling and defines its appropriate design resistance.
