Timber Construction Manual

Since 1952, the American Institute of Timber Construction has been the leading organization in the United States for the wood and timber construction industries and allied interests in building construction, architecture, and engineering. AITC-recommended building and design codes for wood-based structures are considered authoritative in the U.S. building industry.
