There are many types of structural composite lumber (SCLs) commercially available now, and some new SCLs may come on stream in the near future. The SCLs that have prevailed in North America can be exemplified by glue-laminated timber (glulam), laminated veneer lumber (LVL), parallel strand lumber (PSL), and oriented strand lumber (OSL) or laminated strand lumber (LSL). Of these, glulam, LVL, and PSL are in mature stages, while OSL and LSL are still in their infant stages. The growing market potential of LSL is high because the LSL manufacturing technology can be further improved, particularly as its strand orientator (aka orienter) is substantially improved. Consequently, the production cost of LSL can be reduced and product properties can be enhanced. In general, different types of SCLs can be engineered to meet structural performance. The manufacture of SCL relies heavily on experience rather than the laws of science. Unfortunately, some experiences are biased because they are drawn from the manipulation of one or two variables without consideration of possible interactions with other factors. As a result, many SCL manufacturers have experienced start-up and growing pains in trying to engineer and produce low-cost products for specific applications while maximizing their profit. Nevertheless, the SCL industry has cumulatively amassed a lot of experiences and knowledge about manufacturing quality SCL. These experiences and knowledge are transferable, and any new SCL manufacturers can learn from these experiences and knowledge so that they need not make similar mistakes and go through similar start-up and growing pains as established manufacturers have already experienced. Nearly any new mill will have the same, or similar, equipment and processes as are used in existing mills manufacturing the same type of SCL. New manufacturers often learn from the experiences of the existing mills, both good and bad. However, it is essential to avoid experiencing the same problems encountered by the established mills. Otherwise, new SCL mills will fail to have a competitive edge over existing mills. One of my objectives in writing this book is to provide comprehensive information on the basics of SCL manufacturing. Another objective is to share my knowledge about SCL, experiences in research and development of SCLs, and practical experiences in the field. Hopefully, this book will help new manufacturers not make the same mistakes as established manufacturers, as well as assist established manufacturers with getting rid of bad practices. Although most of the basic information and knowledge of manufacturing different SCLs in this book can be found in existing published reports and books, this is probably the first book focused on SCL that covers the gamut of SCL manufacturing issues, including raw materials, equipment, processes, manufacturing parameters, challenges, and solutions for various kinds of SCL manufacturers. I have also attempted to highlight the important avenues necessary to make quality products at minimal production costs, and given my own thoughts of further improvement in product quality, processes and equipment.

The 2005 Edition of the National Design Specification for Wood Construction was approved as an American National Standard on January 6, 2005. The 2005 NDS was developed as a dual format specification incorporating design provisions for both allowable stress design (ASD) and load and resistance factor design (LRFD). The NDS is adopted in all model building codes in the U.S. and is used to design wood structures worldwide.

The introductory course in natural resources is broader and more diverse than ever. Today's students need to know how to manage forest, wildlife, watershed, and range resources in a variety of environments and serving the needs of myriad stakeholders. To that end, Chad Dawson has built on the foundation established by him and the late John Hendee to bring Introduction to Forests and Renewable Resources thoroughly up to date. The Ninth Edition has been reorganized to better address content—for example, policy and the differences between managing federal, state, and private land—that applies to all resources. While forests continue to be emphasized, more coverage is provided to other resources and to achieving management goals for multiple resources when considering topics like fire and recreation.

Timber construction is one of the most prevalent methods of constructing buildings in North America and an increasingly significant method of construction in Europe and the rest of the world. Timber Engineering deals not only with the structural aspects of timber construction, structural components, joints and systems based on solid timber and engineered wood products, but also material behaviour and properties on a wood element level. Produced by internationally renowned experts in the field, this book represents the state of the art in research on the understanding of the material behaviour of solid wood and engineered wood products. There is no comparable compendium currently available on the topic - the subjects represented include the most recent phenomena of timber engineering and the newest development of practice-related research. Grouped into three different sections, 'Basic properties of wood-based structural elements', 'Design aspects on timber structures' and 'Joints and structural assemblies', this book focuses on key issues in the understanding of: timber as a modern engineered construction material with controlled and documented properties the background for design of structural systems based on timber and engineered wood products the background for structural design of joints in structural timber systems Furthermore, this invaluable book contains advanced teaching material for all technical schools and universities involved in timber engineering. It also provides an essential resource for timber engineering students and researchers, as well as practicing structural and civil engineers.

Sustainability of Construction Materials, Second Edition, explores an increasingly important aspect of construction. In recent years, serious consideration has been given to environmental and societal issues in the manufacturing, use, disposal, and recycling of construction materials. This book provides comprehensive and detailed analysis of the sustainability issues associated with these materials, mainly in relation to the constituent materials, processing, recycling, and lifecycle environmental impacts. The contents of each chapter reflect the individual aspects of the material that affect sustainability, such as the preservation and repair of timber, the use of cement replacements in concrete, the prevention and control of metal corrosion and the crucial role of adhesives in wood products. Provides helpful guidance on lifecycle assessment, durability, recycling, and the engineering properties of construction materials Fully updated to take on new developments, with an additional nineteen chapters added to include natural stone, polymers and plastics, and plaster products Provides essential reading for individuals at all levels who are involved in the construction and selection, assessment and use, and maintenance of materials

Introduces engineers, technologists, and architects to the design of wood structures, serving either as a text for a course in timber design or as a reference for self-study. A large number of practical design examples are provided throughout. This edition (2nd, 1988) integrates the new wood design criteria published in the 1991 National Design Specification for Wood Construction and the new seismic design requirements which are included in the 1988 and 1991 editions of the Uniform Building Code.
