Erratum:Impact statement on “Sheathing braced design of cold-formed steel structural members subjected to torsional buckling” [Structures 20, (2019), 489–509]

Sheathing board attached to cold-formed steel (CFS) wall panels offers a bracing effect against the various instability failure modes of wall frame studs. The benefits of incorporating the bracing effect of sheathing in CFS structural member design has been globally accepted. However, until the present study, there was no design approach available in the existing design standards globally to design sheathing boards against torsional buckling of CFS structural members. The current AISI, European, and Australian/New Zealand design standards propose similar sheathing stiffnesses and recommend using stiff steel sheeting to brace the slender CFS structural members against failure. In particular, the highly slender CFS structural members are vulnerable to failure in torsional buckling, thereby leading to a pull-through failure in sheathing boards. Hence, this investigation is focused on torsional buckling of CFS wall frame studs and associated failure modes in sheathing boards. The proposed design method consists of two simple design steps: (i) determine the sheathing stiffness demand for each sheathing fastener connection in the CFS wall frames; (ii) calculate the stiffness of the sheathing fastener connection using the empirical equation developed. The proposed empirical equation is based on the geometric properties of the CFS stud and material properties of the sheathing board. The design method's validity is verified for various CFS stud dimensions and various sheathing board materials, which are typically used in industry. Currently, this design method is based on the nominal design strength of CFS wall frame studs. Thus, the design method can be adopted in future revisions of the AISI, European, and Australian/New Zealand design specifications. © 202
