In the triumvirate of dominant structural building materials--wood,metal, and masonry--each has its advantages, but none are as intertwinedwith the human spirit as wood. Thirty-five public buildings illustrate how heavy timber framing can address familiar programmatic issues such as structure, economics, aesthetics, and sustainability. Timber framing can also have a positive effect on human emotions and physiology. In addition to being warm to the touch, wood building interiors have been widely proven to reduce blood pressure and heart rate and to speed convalescence in health care facilities. More than 450 photos, plans, and diagrams show how wood framing components from solid timbers to glulams and peeled logs are designed for durability and expressiveness. The finished projects aptly demonstrate what it means not only to shape buildings, but how they shape us.
Der Holzbau ist seit einigen Jahren einer der innovativsten Bereiche des Bauwesens. Die Geschwindigkeit, mit der neue Produkte in die Praxis eingeführt werden, ist im Vergleich zu anderen Baustoffen fast atemberaubend. So gewinnt der Holzbau im Gewerbe- und Hallenbau, aber auch im mehrgeschossigen Wohn- und Bürobau kontinuierlich an Marktanteil. Dieses Buch vermittelt wesentliche Kenntnisse und Fertigkeiten, die für den Entwurf, die Bemessung und die Konstruktion von Holzkonstruktionen für typische Bauwerke erforderlich sind. Besonderes Augenmerk wird auf die spezifischen Eigenschaften von Holz und Holzwerkstoffen im Vergleich zu anderen Baustoffen gelegt. Dies betrifft die zahlreichen Vorteile, wie z. B. das vergleichsweise geringe Gewicht, die gute Verarbeitbarkeit des Hochleistungswerkstoffs und die große Vielfalt an Montagetechniken, aber auch die Herausforderungen, die sich aus der Materialanisotropie und aus der Anfälligkeit für natürliche Schädlinge ergeben. In jedem Kapitel werden zunächst die wesentlichen Phänomene erläutert und erst danach in Zusammenhang mit Regelwerken gebracht. Damit soll das Grundverständnis für die Zusammenhänge und Abhängigkeiten im Holzbau unterstützt werden, das die wesentliche Grundlage für kreative Ingenieurarbeit ist.
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.
Woodworking has been one of the most important technologies from the earliest times. Carpentry was important for buildings and bridges and as an integral part of most construction processes. The history of this subject has been explored by a variety of scholars, from archaeologists who have studied medieval timber techniques to engineers who have been interested in the development of bridges. The different studies have explored the methods of carpentry, the behaviour of the structures that were built and even the economic and social histories behind the development of carpentry techniques. This book collects together a number of papers representing this full range of scholarship as well as providing a general review of work in the field.
