Laser-welding is a high precision fabrication process suitable for joining a wide range of steels and stainless steels. Laser-welded structural stainless steel members, for which there are currently little experimental data owing to their recent introduction to the construction industry, are the focus of the present study. To address the lack of test data and to investigate their structural response, a total of 9 stub column tests and 22 flexural buckling tests (14 buckling about the minor axis and 8 about the major axis) have been performed on laserwelded austenitic stainless steel I-section members. Complementary tensile coupon tests, initial geometric imperfection measurements, and residual stress measurements have also been carried out and are reported herein. Based on the results obtained, a representative residual stress pattern is proposed, the design provisions of Eurocode 3 Part 1.4 and the continuous strength method are assessed, and column buckling curves for laser-welded stainless steel I-section members are recommended.

“…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.…”

“…Gardner et al [21] also proposed revised slenderness limits for the classification of circular hollow sections, leading to improved capacity predictions than the codified limits, compared to previous limits. Although comprehensive research has been conducted on the local buckling behaviour of CHS, research into the member stability remains relatively scarce, despite some previous study on columns [1][2][3] and beam-columns [2,3]. The structural performance of CHS members requires further investigation and this is therefore the subject of the present study.…”

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.

This paper describes a series of tests on austenitic stainless steel welded I-columns. Two stub column tests and seven long column tests were carried out. Geometric dimensions, local and overall imperfections of the columns were measured. Material properties of the columns were obtained from tensile coupon and stub column tests. The material enhancement due to the shear cutting in the fabrication of the columns was also measured. The effects of this material enhancement and the residual stresses caused in welding, on the flexural buckling strengths of columns were evaluated using finite element method. The strengths obtained from long column tests were compared with the strengths predicted by European design code (Eurocode3: Part 1.4) and American design code (SEI/ASCE-8-02). It is concluded that the column curve for welded I-column buckled in minor axis of European design code is more reliable in the strength predictions for welded I-columns buckled in major axis and columns buckled in minor axis.
