This paper provides the results of numerical and experimental investigations of buckling problems of cold‐formed, thin‐walled channel beams with double‐box flanges under pure bending. A local and global buckling analysis is realised numerically with the use of the finite strip method. A local buckling has been experimentally studied and also numerically with the use of the finite element method. Experimental tests of beams subjected to pure bending are conducted. The results of numerical and experimental investigations are presented and compared. A fundamental influence of double‐box flanges on the critical load is shown.

“…An experimental study on laser-welded CFS built-up beams was conducted by Landolfo et al (2008). Paczos and Wasilewicz (2009) have investigated the buckling studies on lipped CFS I-shaped beam with anti-symmetrical bends, which increase the load capacity, and while designing, special attention needs to be paid to their size. Magnucka-Blandzi (2010) has studied the behaviour of CFS channel beams with doublebox flange beams.…”

The aim of the present study is to examine the behaviour of cold-formed steel (CFS) lipped channel built-up I-section with edge and intermediate web stiffeners under bending. Initially, the section dimension of length, width of the flange and depth of the sections are optimized numerically and finally, it is validated with the test results. All the select cross-section dimensions have satisfied the pre-qualified beam dimensions. Numerical analysis is carried out using the software ABAQUS. Totally, four section geometries are tested experimentally. After validation, a total of 75 parametric studies are carried out using the verified finite element model. All the results are compared with the direct strength method specifications for CFS structures and the suitable design modifications are detailed.

“…Experimental investigations, distribution of stresses and displacements of cold-formed thin-walled beams were presented by Paczos and Magnucki [6] and Belingardi and Scattina [7]. The other works on this subject were Biegus et al [8], Paczos and Wasilewicz [9], Mahendran and Jeyaragan [10]. Comparison of theoretical results with experimental ones helps to improve mathematical models of beams.…”

Demand for thin-walled structures has been increasing for many years. Cold- formed, thin-walled channel beams are the subject of presented research. The local elastic buckling and limit load of these beams subjected to pure bending are investigated. This study includes numerical investigation called the Finite Strip Method (FSM). The presented results give a deep insight into behaviour of such beams and may be used to validate analytical models. The number of works devoted to the theory of thin-walled structures has been steadily growing in recent years. It means that is an increasing interest in practical methods of manufacturing cold-formed thin-walled beams with complicated cross-sections, including also beams with web stiffeners. The ratio of transverse dimensions of beam to its wall-thickness is high, therefore, thin-walled beams are prone to local buckling that may interact with other buckling modes. The stability constraints should be always considered when using cold-formed thin-walled beams.
