The American Iron and Steel Institute (AISI) has published AISI D110-16 - Cold-Formed Steel Framing Design Guide, 2016 Edition, to assist practicing structural engineers in designing cold-formed steel framing systems. The guide provides a general review of basic structural principles and five comprehensive design examples that cover wind-bearing and axial load-bearing stud walls and joists.

This issue of the design guide updates the 2007 edition and is available for purchase at the AISI Steel Store, www.steel.org.

The design examples featured in AISI D110-16 illustrate both screwed and welded connection details. They are based on AISI S100-12 - North American Specification for the Design of Cold-Formed Steel Structural Members, 2012 Edition.


Updates to AISI D110-16 include:

• Revised design examples that conform to the latest cold-formed steel framing design standards, including AISI S100-12 and AISI S240-15, North American Standard for Cold-Formed Steel Structural Framing, 2015 Edition,
• The use of load combination factors as required by ASCE/SEI 7-10, Minimum Design Loads for Buildings and Other Structures,
• The inclusion of distortional buckling calculations in the design example of a wind-bearing infill wall with an unsheathed design approach,
• Modification of the slide clip detail for connecting wind-bearing studs that is more typically used in modern construction,
• Modification of  an alternative parapet design using cantilevering HSS posts to reflect an approach with more flexibility for field installation,
• A new design example to illustrate the design of cold-formed steel floor and axial load-bearing wall framing with ledger framing, and
• The addition of Appendix L, which provides a complete listing of Technical Notes available from the Cold-Formed Steel Engineers Institute (CFSEI).
