THE DEFINITIVE DESIGN AND CONSTRUCTION INDUSTRY SOURCE FOR BUILDING WITH WOOD NOW IN A THOROUGHLY UPDATED SIXTH EDITION Since its first publication in 1966, Timber Construction Manual has become the essential design and construction industry resource for building with structural glued laminated timber. Timber Construction Manual, Sixth Edition provides architects, engineers, contractors, educators, and related professionals with up-to-date information on engineered timber construction, including the latest codes, construction methods, and authoritative design recommendations. Content has been reorganized to flow easily from information on wood properties and applications to specific design considerations. Based on the most reliable technical data available, this edition has been thoroughly revised to encompass: A thorough update of all recommended design criteria for timber structural members, systems, and connections An expanded collection of real-world design examples supported with detailed schematic drawings New material on the role of glulam in sustainable building practices The latest design and construction codes, including the 2012 National Design Specification for Wood Construction, AITC 117-2010, and examples featuring ASCE 7-10 and IBC 2009 More cross-referencing to other available AITC standards on the AITC website Since 1952, the AMERICAN INSTITUTE OF TIMBER CONSTRUCTION has been the national technical trade association of the structural glued laminated timber industry. AITC-recommended building and design codes for wood-based structures are considered authoritative in the United States building industry.

Much research has been done recently, and more is now in progress, to increase the effectiveness under tropical conditions of methods which have been developed in Europe for preserving timber. This book attempts to bring together the results of some of these studies. I have not attempted to cover the tropical zones of Central and South America as this would have extended the book beyond its limits. But I am grateful to the authors who have contributed chapters dealing with the different aspects and solutions of the problems of the tropical areas of the Old World. The International Research Group for Wood Preservation (The I.R.G.) at its annual meetings in different countries has provided a valuable forum for cooperation in this developing field. Anyone concerned with the subject would be well advised to study the publications issued by this group. Their office is at Drottning Kristinas vag 47C S - 11428 Stockholm, Sweden. Although timber is a renewable resource there is every reason why it should not be wasted through premature decay or the ravages of termites etc., when effective measures for its preservation are available and, if correctly applied, can greatly reduce the cost of maintaining timber structures.
