The Direct Strength Method (DSM) of cold-formed steel member design employs local, distortional, and global cross-section elastic buckling analysis with empirically derived “direct” expressions to predict member strength. ...

Laterally braced cold-formed steel beams generally fail due to local and/or distortional buckling in combination with yielding. For many cold-formed steel (CFS) studs, joists, purlins, or girts, distortional buckling may ...

Rod or cable bracing is often provided in metal buildings to develop lateral resistance against wind or seismic loads in the ‘long’ direction of the building, i.e., in the direction perpendicular to the primary frames. ...

The objective of this paper is to investigate the ductility demand for typical cold-formed steel (CFS) connections when advanced high strength steel (AHSS) is used for the components. Although currently AHSS is mostly used ...

Due to the weak torsional stiffness of cold-formed thin-walled channel members, distortional buckling behavior maybe controlled the ultimate load-capacity under certain conditions. Therefore, a new section reinforced by ...

Cold-formed steel members are increasingly used in the construction industry due to their favorable strength-to-weight ratio and cost efficiency. Knowledge of the elevated temperature behavior of cold-formed steels is ...

The objective of this paper is to explore the optimization of building roofs composed of bare cold-formed steel deck profiles when subjected to lateral demands such that the diaphragm response dominates the roof design ...

Cold-formed steel members often need to be opened in the web due to the passage of the building system pipeline. In general stiffeners of the web maybe strengthen their structural performance. In the field of cold-formed ...

Second-generation trapezoidal sheeting, characterised by longitudinal stiffeners in webs and flanges, is loaded near a support by a concentrated force and a bending moment. Currently, design codes predict related failure ...

The objective of this paper is to describe testing and analysis of cold-formed steel (CFS) stud walls braced by both discrete steel bridging and gypsum sheathing. A focused series of tests was conducted to determine the ...
