“…Cold-formed stainless steel hollow sections are becoming an attractive choice in a range of structural applications since they combine the durability advantages of stainless steel with the aesthetic appeal, structural efficiency and potential for concrete infilling [4][5][6][7][8] of tubular profiles. The tested cross-sections were formed from austenitic and duplex stainless steels.…”

Stainless steel has been gaining increasing use in a variety of engineering applications due to its unique combination of mechanical properties, durability and aesthetics. Significant progress in the development of structural design guidance has been made in recent years, underpinned by sound research. However, an area that has remained relatively unexplored is that of combined loading. Testing and analysis of stainless steel cross-sections under combined axial load and bending is therefore the subject of the present paper and the companion paper [1]. The experimental programme covers both austenitic and duplex stainless steels, and five cross-section sizes including three square hollow sections (SHS) and two rectangular hollow sections (RHS). In total, five stub column tests, five four-point bending tests, 20 uniaxial bending plus compression tests and four biaxial bending plus compression tests were carried out to investigate the cross-sectional behaviour of stainless steel tubular sections under combined loading.

Improved design rules for stainless steel cross-sections under combined loading are also sought through extension of the deformation-based Continuous Strength Method (CSM).

“…This is because the strain hardening of stainless steels in compression is much higher than that of stainless steels in tension. Tests on circular CFSST short columns under axial compression were carried out by Lam and Gardner [9]. They investigated the effects of the tube thickness, concrete compressive strength and proof stress on the behavior of CFSST columns under axial loading.…”

“…Previous experimental and numerical studies into the behaviour and design of circular hollow section structural members have been carried out, aiming at verifying their performance under varying loading conditions, assessing the efficiency of the established design codes, and developing more economic design approaches. A series of stub column [1][2][3][4][5][6][7][8][9][10] and bending [3,11,12] tests have been performed on CHS of varying cross-section classes, in order to investigate their local buckling behaviour and the corresponding loading-carrying and deformation capacities under isolated loading conditions. Zhao et al [13] conducted a comprehensive experimental programme on eccentrically loaded stub columns to study the structural performance of stainless steel CHS subjected to combined axial load and bending moment.…”

This paper presents a comprehensive experimental and numerical study of the global stability of stainless steel circular hollow section (CHS) structural members subjected to combined axial load and bending moment. The experimental investigation, which was carried out on two grade 1.4301 austenitic stainless steel cross-section sizes (CHS 60.5×2.8 and CHS 76.3×3), included material coupon tests, initial geometric measurements, two column tests, and ten beam-column tests. The test results were employed in a parallel numerical simulation programme for the validation of finite element (FE) models, by means of which a series of parametric studies were carried out to extend the available results over a wider range of cross-section sizes, member lengths and loading combinations. The experimentally and numerically derived data were used to assess the structural performance of CHS beamcolumns and to determine the accuracy of the current design provisions given in the European code, American specification, Australian/New Zealand standard, and other recent proposed approaches. Generally, all the existing design methods were shown to yield a high degree of Zhao, O., Gardner, L., & Young, B. (2016). Testing and numerical modelling of austenitic stainless steel CHS beam-columns. Engineering Structures, 111,[263][264][265][266][267][268][269][270][271][272][273][274] scatter in the prediction of beam-column strength, with both conservative and over-predicted capacities. The scatter was attributed mainly to inaccurate predictions of the column buckling and bending end points of the design beam-column interaction curves (i.e. member strengths under pure compression and pure bending, respectively) and inaccurate interaction factors.The development of improved provisions for the design of stainless steel circular hollow section beam-columns is currently underway.
