2018 National Design Specification® (NDS) for Wood Construction

2018 NDS
  • The 2018 National Design Specification (NDS) for Wood Construction was developed by the American Wood Council's (AWC) Wood Design Standards Committee and has been approved by ANSI as an American National Standard. The 2018 NDS is referenced in the 2018 International Building Code. Significant additions to the 2018 NDS include new Roof Sheathing Ring Shank nails and fastener head pull-through design provisions to address increased wind loads in ASCE 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures. Purchased copy includes integral commentary.

2018 NDS Supplement

2018 NDS Supplement
  • Design provisions in the NDS are integral with design values in the NDS Supplement. As such, it is not appropriate to mix design values and provisions from different editions of the NDS. The NDS Supplement contains design values for sawn lumber, structural glued laminated timber, and round timber poles and piles.

Other Resources

The following publications are available separately from, but compliment, the 2018 NDS and 2018 NDS Supplement.

Manual for Engineered Wood Construction, 2018 Edition

(Available only in Electronic Format)

2018 Manual for Engineered Wood Construction
  • The 2018 Manual for Engineered Wood Construction contains design information for structural lumber, glued laminated timber, structural-use panels, shear walls and diaphragms, poles and piles, I-joists, structural composite lumber, cross-laminated timber, and over 40 details are included in the chapter on connections. The Manual provides design information on structural applications of most wood-based products and their connections that meet the requirements of the referenced standards. The Manual is a dual format document incorporating design provisions for both allowable stress design (ASD) and load and resistance factor design (LRFD). Each product chapter contains information for use with this Manual and the National Design Specification® (NDS®) for Wood Construction. Chapters are organized to parallel the chapter format of the NDS.

2015/2018 Structural Wood Design Examples

2015/2018 Structural Wood Design Examples
  • 2015/2018 Structural Wood Design Examples is intended to aid instruction in structural design of wood structures using both Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD). It contains over 20 design examples and complete solutions for wood member design, connections, and shear walls. Solutions have been developed based on the 2015 and 2018 National Design Specification®(NDS®) for Wood Construction, and the 2015 Special Design Provisions for Wind and Seismic (SDPWS), as appropriate. References are also made to the 2015 and 2018 Wood Frame Construction Manual (WFCM) for One- and Two- Family Dwellings.
