The strength of thin-walled stainless steel columns has been investigated extensively over the past few years. In European standards, the concept of section classification for determining the cross-section capacity is used. In this system, for Class 4 cross-sections, the Effective Width Method (EWM) must be used to account for the effect of local buckling. Because of the complexity and limitations of this method, other methods have been developed, such as the Direct Strength Method (DSM) for cold-formed thin-walled profiles and the Continuous Strength Method (CSM), initially established for members made of nonlinear metallic materials. In the CSM, to take advantage of strain hardening, a deformation-based design approach employing a continuous relationship between the cross-sectional slenderness and the cross-sectional deformation capacity is used. To a large extent, the CSM yield accurate predictions, especially in the low slenderness range where the current DSM design procedures for members submitted to pure compression tends to produce conservative predictions, for materials with pronounced strain hardening such as stainless steel alloys. The present paper presents an extension of the traditional DSM which provides accurate design strength predictions in the low slenderness range for stainless steel thin-walled section columns failing by distortional, local and overall buckling. It contains practical information concerning the reference experimental data and draws conclusions about the justification of the proposed analytical formula. The paper is divided into three main parts: the description of the database, the establishment of the design model and a reliability analysis of the method. [less ▲]

This paper presents a series of 48 full-scale tests on press-braked stainless steel lipped channel section columns subjected to concentric compression. The tests were carried out between fixed ends in the Structures Laboratory of the University of Liège and the test specimens were designed such that distortional buckling developed in the section prior to overall flexural-torsional buckling. The stainless steel alloy was 1.4003 chromium weldable steel, popularly known as 3Cr12. Three different geometries were tested using the same experimental set-up. A critical summary of the standards and methods for calculating the carrying capacity of cold-formed stainless steel compression members is presented in a companion paper by the same authors.

This paper provides a critical summary of the European standards and design methods available for calculating the strength of cold-formed stainless steel compression members. The standards considered (so far mainly applied to columns failing by flexural buckling) are applied to the case of lipped channel section columns failing by combined distortional and overall flexural-torsional buckling. As observed during the tests presented in a companion paper, distortional buckling is found to have a considerable effect on the cross-section resistance and is prone to interact with the global flexural-torsional mode. It is investigated how the different formulations account for the two buckling modes and their interaction and how accurate strength predictions they provide. A new Direct Strength Method taking into account these failure modes is then presented and compared to the tests results. [less ▲]
