ANSI / AF&PA SDPWS-2005 - Special Design Provisions for Wind and Seismic standard with Commentary covers materials, design and construction of wood members, fasteners, and assemblies to resist wind and seismic forces. 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).

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.

The Wood Design Package includes the following publications: NDS for Wood Construction with Commentary, NDS Supplement: Design Value for Wood Construction, Special Design Provisions for Wind and Seismic with Commentary (sold separately), ASD.LRFD Manual for Engineered Wood Construction. Revisions to the 2012 ASD/LRFD Structural Wood Design Solved Example Problems manual continue and its availability will be announced once it is updated. Please note that additional changes to design values for southern pine dimension lumber are anticipated in 2013. A new addendum to the 2012 NDS Supplement will also be provided once those values are available. More information.

The Wood Design Package 2005 contains the following publications: NDS for Wood Construction, Supplement: Design Values for Wood Construction, Special Design Provisions for Wind and Seismic (SDPWS) Standard with Commentary, ASD/LRFD Manual for Engineered Wood Construction, 2005 Edition The 2005 Edition of the National Design Specification for Wood Construction was approved as an American National Standard on January 6, 2005. The 2005 NDS was developed as a dual format specification incorporating design provisions for both allowable stress design (ASD) and load and resistance factor design (LRFD). The NDS is adopted in all model building codes in the U.S. and is used to design wood structures worldwide.
