Lori Koch, PE / American Wood Council

AWC's National Design Specification (NDS) for Wood Construction 2015 is referenced in US building codes and used to design wood structures worldwide. Participants in this SE University session learned about some of the significant changes in the 2015 NDS and Supplement relative to previous editions. Design considerations related to fire retardant treated and preservative treated wood, as well as connection design considerations, were highlighted. Included in the session were discussions of both cross-laminated timber, which is new to the 2015 IBC and NDS, and the emerging concept of mass timber.
