Since its first publication in 1966, Timber Construction Manual has become the definitive design and construction industry source for building with wood, both sawn lumber and structural glued laminated timber. Timber Construction Manual, Fifth Edition features an improved organization of content to provide architects, engineers, contractors, educators, the laminating and fabricating industry, and all others having a need for reliable, up-to-date technical data and recommendations on engineered timber construction with essential knowledge of wood and its application to specific design considerations. Based on the most reliable technical data available, this defining guide has been thoroughly revised to encompass: The latest design procedures for timber construction, featuring thorough updates of all recommended design criteria for timber members, systems, and fasteners A simplified design procedure for pitched and tapered curved beams An entirely new chapter on Load and Resistance Factor Design (LRFD) and an updated section on the chemical properties of wood The latest design and construction codes, including the 2001 National Design Specification for Wood from the National Forest Products Association, AITC 117-2004, and examples featuring ASCE 7-02 and IBC 2003 More cross-referencing to other available AITC standards and less superfluous full citations result in a leaner book with more useful, up-to-date information
