The American Iron and Steel Institute (AISI), in partnership with the Steel Deck Institute, has completed a project to evaluate provisions for determining the strength of arc spot welds included in AISI S100-12, North American Specification for the Design of Cold-Formed Steel Structural Members, 2012 Edition. These provisions have not been revised since 1999. Since then, four new research studies have created and tested arc spot welded connections, considerably expanding the database of available tests. Details of the testing and results are included in a report titled: “RP16-1: Resistance of Arc Spot Welds – Update to Provisions.” A free download is available from AISI.
