Direct Strength Prediction of Cold-Formed Steel Beam-Columns
(2016)
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. ...
Distortional Buckling of Cold-Formed Steel Members in Bending
(2005)
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 ...
Strength and stiffness of metal building rod brace anchor connections
(2018-03)
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. ...
Ductility Demands on CFS Structural Connections of Advanced High Strength Steel
(2020-10-20)
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 ...
Structure Performance of Cold-formed Steel columns reinforced by Channel Sleeve under Axial and Eccentric compression
(2020-10-20)
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 properties at elevated temperature: review and proposed equation
(2020-10-20)
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 ...
Topology Optimization of Cold-Formed Steel Deck Diaphragms with Irregularities
(2020-10-20)
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 ...
Effect of holes and stiffeners on the behavior of Eccentric loaded cold-formed steel built-up channel columns - numerical investigation
(2020-10-20)
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 ...
The Direct Strength Method for Combined Bending and Web Crippling of Second-Generation Trapezoidal Steel Sheeting
(2020-10-20)
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 ...
Performance of CFS Walls Braced with Bridging and Sheathing
(2020-10-20)
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 ...
