2015 Wood Design Package


2015 National Design Specification® (NDS) for Wood Construction

The 2015 National Design Specification (NDS) for Wood Construction was developed by AWC's Wood Design Standards Committee and approved as a Standard by ANSI (American National Standards Institute) on September 30, 2014. The 2015 NDS is referenced in the 2015 International Building Code. One significant addition to the 2015 NDS is a new product design chapter for cross-laminated timber (CLT). Purchased copy includes integral commentary.

Purchase of the 2015 NDS includes the 2015 NDS Supplement and the 2015 SDPWS.

2015 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.

2015 Special Design Provisions for Wind and Seismic

The ANSI/AWC 2015 Special Design Provisions for Wind and Seismic (SDPWS) provides criteria for proportioning, designing, and detailing engineered wood systems, members, and connections in lateral force resisting systems. Engineered design of wood structures to resist wind or seismic forces is either by allowable stress design (ASD) or load and resistance factor design (LRFD). Nominal shear capacities of diaphragms and shear walls are provided for reference assemblies. Purchased copy includes integral commentary.

Other Resources

The following publications are available separately from, but compliment, the 2015 NDS and 2015 NDS Supplement.

Manual for Engineered Wood Construction, 2015 Edition

(Available only in Electronic Format)

The 2015 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 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.
