The carbon emissions generated by concrete and steel construction are well-known. Why then are we not using more carbon-friendly building materials? In a passionate and compelling argument Paul Brannen advocates the use of timber in buildings wherever possible. His controversial and counterintuitive argument is clear: planting trees is not enough to reduce carbon, we also have to chop them down and use more wood in our buildings and cities. This is the first book to take timber from the margins to the mainstream, from the forests to the cities. The book tackles head-on questions about sustainability, safety, the biodiversity of commercial forests and the pressures on land use. The case for timber as a construction material is persuasively made – the creation of new engineered timbers with the structural strength of steel and concrete enable us for the first time to build wooden skyscrapers – and draws on the latest developments in engineering and material science. In addition to the familiar forestry models, the book advocates alternatives such as wood farming and agroforestry that bring with them added biodiversity gains for farms. With the built environment currently responsible for 40 per cent of the world's carbon emissions, Brannen's message is unequivocal: we must change how we build. Timber! offers fresh and inventive ideas that over time could see our expanding cities storing more carbon than our expanding forests.

This book is a compilation of selected papers presented in the International Conference on the theme ‘Wood is Good: Current Trends and Future Prospects in Wood'. The contents of the book deal with recent innovations, trends and challenges in wood science and are grouped in five distinct sections. They cover a wide range of topics like wood variability, processing and utilization, wood protection, wood-based composites, wood energy and the role of wood in mitigating climate change. With the ever increasing human population and growing demand for wood, this book offers valuable insights for better understanding and efficient utilization of this wonderful gift of nature. This book will be useful to researchers, professionals, and policy makers involved in forestry and wood related areas.

This text provides a concise and practical guide to timber design, using both the Allowable Stress Design and the Load and Resistance Factor Design methods. It suits students in civil, structural, and construction engineering programs as well as engineering technology and architecture programs, and also serves as a valuable resource for the practicing engineer. The examples based on real-world design problems reflect a holistic view of the design process that better equip the reader for timber design in practice.This new edition now includes the LRFD method with some design examples using LRFD for joists, girders and axially load members. is based on the 2015 NDS and 2015 IBC model code. includes a more in-depth discussion of framing and framing systems commonly used in practice, such as, metal plate connected trusses, rafter and collar tie framing, and pre-engineered framing. includes sample drawings, drawing notes and specifications that might typically be used in practice. includes updated floor joist span charts that are more practical and are easy to use. includes a chapter on practical considerations covering topics like flitch beams, wood poles used for footings, reinforcement of existing structures, and historical data on wood properties. includes a section on long span and high rise wood structures includes an enhanced student design project
