The American Lumber Standard Committee (ALSC) Board of Review has approved changes to design values for 2"- 4" thick, 2"- 4" wide, Southern Pine #2 Dense and 2x4 Mixed Southern Pine #2 and all lower grades (i.e. #3, Stud, Construction, Standard, and Utility) with a recommended effective date of June 1, 2012, to allow for their orderly implementation. For more information, visit www.spib.org and www.southernpine.com.
In advance of the implementation date, AWC has developed an addendum to the NDS Design Values for Wood Construction that provides design values for these sizes and grades of Southern Pine and Mixed Southern Pine to use with the 2012 NDS, 2005 NDS, and the 2001 NDS. AWC has also developed an addendum to the Design Values for Joists and Rafters that provides design values for these sizes and grades of Southern Pine and Mixed Southern Pine to use with the Span Tables for Joists and Rafters.
