For nearly 60 years, Timber: Structure, Properties, Conversion, and Use has been the authoritative text on timber technology. Now in its seventh edition, this book remains a vital resource, providing accurate, comprehensive, and fact-driven information for students and professionals in the field. From basic coverage of timber structure, properties, processing, and utilization, to more in-depth scientific investigations, this book covers all the issues and topics of concern to readers with a wide range of levels of sophistication. Timber technology has not stood still since the last revision; Timber: Structure, Properties, Conversion, and Use has kept the pace, exploring such high-tech topics as computer-aided wood identification and log conversion, radio frequency drying of wood, enhancement of wood with plastics, application of preservatives with high-pressure vacuum systems, and the development and application of flame-retardant solutions. Other timely updates include enlarging the chapter on mechanical performance to cover elastic behavior, toughness, and the use of structural-sized timber for strength tests. The chapter on board materials has also been extensively updated and enlarged to include information on new boards and structural composites that have emerged since the last edition. One of the most important strengths of Timber: Structure, Properties, Conversion, and Use is its versatility as a reference for timber professionals while remaining approachable to students in the field. Evidence of the book?s comprehensiveness and versatility becomes clear as it teaches readers about such wide-ranging topics as: identification and nomenclature of timbers variability in cellular features between species principal chemical constituents in timber structural variability caused by natural defects such as bark pockets, resin streaks, and brittleheart determination of density and moisture content in timber thermal and acoustic properties of wood conversion equipment such as circular saws, band saws, frame saws, and chipper canters health and safety issues in the industry adhesives, metal connectors, and joint design forest and millyard pests application of preservatives and finishes From basic identification and timber nomenclature to methods of sap displacement and tests of electrical conductivity, Timber: Structure, Properties, Conversion, and Use covers it all. And while it is no longer possible for any one individual to write authoritatively on every aspect of timber technology, embracing as it does structure, properties, conversion, utilization, and behavior in service, J. M. Dinwoodie has gathered expert opinions and expanded on original author H. E. Desch?s approach and vision to continue to provide the authoritative text on timber technology.
Addressed to the general professional chemist at a level between the undergraduate and the specialist in the field, presents such aspects of modern wood chemistry as anatomy, analysis, the composite nature and chemical composition of wood, and the structure and properties of cellulose, lignin, hemic
This book offers a broad range of options for technically adapting, handling and processing wood with specific wood characteristics. It starts by discussing wood anatomy and the general factors leading to the formation of wood characteristics. The individual characteristics are then categorized into four groups: 1. Wood characteristics inherent in a tree’s natural growth. 2. Biotically-induced wood characteristics. 3. Abiotically-induced wood characteristics. 4. Types and causes of cracks. New to this English edition is a comparison of wood characteristics found in trees from the boreal, temperate and tropical climate zones. The results show a clear relationship between the effects of sunshine duration, the vertical and horizontal angle of radiation, and crown coverage and the way wood characteristics form. The book addresses all those who work with wood professionally: foresters, gardeners and arborists who want to be able to observe a living tree and identify its internal features and the causes of its prominent wood characteristics. Based on the findings described in this book they can determine how to avoid certain undesirable characteristics, or alternatively how to promote favorable ones as the tree and stand grow. Botanists and dendrologists will learn how wood characteristics arise, and how they affect living trees and wood products. The needs of wood technologists seeking to prevent adverse wood characteristics from influencing wood processing, or to enhance favorable wood characteristics, are also addressed.

Wood Deterioration, Protection and Maintenance provides an up to date discussion of the natural durability of wood, wood degradation processes, and methods of structural and chemical protection of wood. Modern active substances in wood preservatives and the relationships between preservative properties, the anatomical structure and moisture content of wood and protective processes involving pressure and/or diffusion driving forces are fully illustrated.
This report presents a comprehensive analysis of the design, construction, inspection, and maintenance of timber bridges.
