Since its first publication in 1966, the “Timber Construction Manual” has become the definitive design and construction industry source for structural glued laminated timber.

The Timber Construction Manual, Fifth Edition features an improved organization of content to provide architects, engineers, contractors, educators, the laminating and fabrication industry, and all others having a need for reliable up-to-date technical data and recommendations on engineered timber construction.

The latest design procedures for timber construction, featuring:

  • Thorough updates of all recommended design criteria for timber structural members, systems, and fasteners
  • A simplified design procedure for pitched and tapered curved beams
  • An entirely new chapter on “Load Resistance Factor Design” (LRFD), and
  • An updated section on the chemical properties of wood.
