National Design Specification® (NDS®) for Wood Construction, 2015
The 2015 Wood Design Package brings together all required elements for design of wood structures in one comprehensive document. It includes design information and examples for wind and seismic conditions, sawn lumber, structural glued laminated timber, structural-use panels, shear walls and diaphragms, poles and piles, I-joists, structural composite lumber, structural connections (nails, bolts, screws), and cross-laminated timber.
The 2015 Wood Design Package includes the publications listed below:
NDS for Wood Construction, 2015 Edition: ANSI/AWC NDS-2015 National Design Specification (NDS) for Wood Construction was approved as an ANSI American National Standard on September 30, 2014. The 2015 NDS was developed by the American Wood Council's (AWC) Wood Design Standards Committee and 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). Includes integral commentary.
NDS Supplement: Design Values for Wood Construction, 2015 Edition: NDS Supplement – Design Values for Wood Construction, 2015 Edition 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 SDPWS Standard ANSI / AWC SDPWS-2015: Special Design Provisions for Wind and Seismic standard 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. Includes integral commentary.
