“…At first a single upright section was experimentally and numerically tested [11,12]. Next the full-scale stability tests of frame modules was conducted [13]. Based on research results for both single upright sections and frame modules authors demonstrate that the design buckling strength of uprights can be conveniently estimated by single section tests, providing that the length of these members is calibrated for the distortional-global interaction mode.…”

The paper presents studies concerning the load-bearing capacity of truss joints with a positive eccentricity resulting from the arrangement of geometric members and the failure mechanisms observed in the joints. Based on the previously conducted experimental study, a numerical model of the tested fragment of the CFS truss with eccentricity in the joint was created and validated. All structural details of the tested truss and the loading method consistent with the experiment were taken into account. The results obtained from a uniaxial tensile tests on a steel samples and results estimated during destructive tests carried out on a full-scale of research model were taken into account in validation of the numerical model. Next, appropriate numerical analyses were carried out and parameters such as the eccentricity size in the joint and the wall thickness of sections (t = 1.0, 1.5 and 4.0 mm) were modified. In the range of the studied wall slenderness from λ > 70 (1.0 mm and 1.5 mm thick), it was confirmed that the resistance of truss joints made from CFS open cross-sections with a positive eccentricity, is greater than the resistance that results from known methods of steel structure dimensioning.

“…The vast majority of storage racks are constructed from CFS so that much of the research in the area of the stability of steel framing is covered by storage racks. The references are for rack uprights including buckling (Bernuzzi and Maxenti, 2014; Casafont et al, 2014; Crisan et al, 2014b; Dinis et al, 2014b; Nedelcu et al, 2014; Ren and Zhao, 2014; Trouncer and Rasmussen, 2014), analysis of frames (Gilbert et al, 2014; Rasmussen and Gilbert, 2013) and connections (Wang et al, 2014d; Zhao et al, 2014). Interaction buckling in the uprights of storage rack frames is clearly an active area of investigation.…”

This article reviews research on cold-formed steel structures published in 2013 and 2014 in three leading journals: the Journal of Structural Engineering, ASCE, Thin-Walled Structures and the Journal of Constructional Steel Research. It also reviews papers published in the three main conferences in the area over the same period. These are Eurosteel 2014 (Naples, Italy), the 7th International Conference on Thin-Walled Structures (Busan, Korea) and the 22nd International Specialty Conference on Cold-Formed Steel Structures (St Louis, MO, USA). Three research areas which have recently been incorporated in the North American Specification NAS S100:2012 or are being incorporated in the Australian/New Zealand Standard AS/NZS 4600 have been highlighted. These are the works on the semi-analytical finite strip method for sections in shear by the author and his colleagues at the University of Sydney, net section rupture by Associate Professor Lip Teh at the University of Wollongong and fire design by Professor Mahendran at Queensland University of Technology.

“…However, these models cannot reproduce sectional deformations, sectional constraints as weld spots, perforations or local effects. Conversely, shell finite element models can handle sectional deformations, perforations, sectional constraints and more particularities of pallet rack structures [4][5][6][7]. Nevertheless, a shell finite element model of a whole pallet rack structure could present a high computational cost.…”

Thin‐walled open cross‐sections are commonly used in steel storage pallet rack structures. In some cases, open sections are employed as beam members. These beam members usually have weld spots along their length in order to reduce the distortional deformation under a flexural load. On the other hand, beam members are typically connected to columns by means of claws, which typically exhibit a nonlinear moment ‐ rotation relationship. These two characteristic should be taken into account in order to properly reproduce their structural response. In this paper, the Generalised Beam Theory (GBT) is used to perform a geometrical nonlinear analysis of a pallet rack beam members taking weld spots and the beam‐to‐column connection behavior into account. The influence of the number and location of weld spots, as well as the beam‐to‐column connection behavior, in the distortional deformation of a beam member is evaluated by means of GBT nonlinear analyses. The results show that the use of a small number of weld spots could be enough to minimize the beam distortional deformation. Moreover, the stiffness of the beam‐to‐column connection also has influence on the beam distortional deformation. Finally, GBT results are successfully compared with shell finite element analyses.
