2018 Wood Design Standards Available Online Robert Glowinski is the President & CEO of the American Wood Council (AWC).
T
he recent approval of the 2018 International Building Code (IBC) and International Residential Code (IRC) is of keen interest to professionals in the construction industry as it often means expanded options for structural applications. In support of these two codes, the American Wood Council has developed two standards: the 2018 National Design Specification® (NDS®) for Wood Construction and 2018 Wood Frame Construction Manual (WFCM). Each has been approved by the American National Standards Institute (ANSI) as American National Standards and both are referenced for wood design in the new IBC and IRC. The 2018 NDS is key to designers of wood buildings and those responsible for oversight and code enforcement, and defines the methods to be followed in structural design with traditional and engineered wood products, as well as the design and fabrication of single and multiple fastener connections. Primary changes in the 2018 NDS include: • Adjustments to fire design provisions for exposed wood members and connections to aid in new applications where fire resistance ratings are required; • Added design provisions for fastener head pull-through in lumber and wood structural panels; • New design provisions for ring shank nails to address increased roof uplift loads in ASCE 7-16; • Added design provisions for stainless steel nail withdrawal; and, • Revised provisions for incised lumber.
