The American Wood Council (AWC) released a revised 2015 Manual for Engineered Wood Construction.
The document contains design information for structural lumber, glued laminated timber, structural-use panels, cross-laminated timber, poles and piles, I-joists, and structural composite lumber. It pertains to structural applications of many wood-based products and their connections in accordance with requirements of referenced standards.
The manual incorporates dual formats, providing design provisions for both allowable stress design and load and resistance factor design. Informational chapters are organized to parallel those found in the National Design Specification for Wood Construction (NDS).
- A new chapter on cross-laminated timber (CLT)
- New and updated tables on minimum sizes to qualify for heavy timber (Type IV) construction that now includes structural composite lumber (SCL) and CLT
- Now organized for use with the AWC 2015 Wood Design Package which includes the 2015 NDS and Commentary, 2015 NDS Supplement: Design Values for Wood Construction, and 2015 Special Design Provisions for Wind and Seismic and Commentary.
The 2015 Manual is available as a free download from the AWC website.
