Materials for Architects and Builders provides a clear and concise introduction to the broad range of materials used within the construction industry and covers the essential details of their manufacture, key physical properties, specification and uses. Understanding the basics of materials is a crucial part of undergraduate and diploma construction or architecture-related courses, and this established textbook helps the reader to do just that with the help of colour photographs and clear diagrams throughout. This new sixth edition has been completely revised and updated to include the latest developments in materials research, new images, appropriate technologies and relevant legislation. The ecological effects of building construction and lifetime use remain an important focus, and this new edition includes a wide range of energy-saving building components.

Current design rules for timber joints with dowel-type fasteners require input parameters such as yield moment and withdrawal capacity, which are determined within the European framework of certification testing. Databases containing these data were assembled. A large scatter was observed. Bespoke series may deliver clear trends. If representative data is considered, these clear trends vanish. Globally valid regression equations are conservative leading to incorrect prediction of failure modes.

Bamboo is in the spotlight as a potential building material in the current pursuit of a CO2-neutral society, due to its rapid maturation and excellent mechanical properties. Despite the growing interest in bamboo in academia and society, there is a lack of systematic understanding of the fabrication, design and construction processes using bamboo as a modern industrial material. This is the first book to describe a new category of structural systems constructed with engineered bamboo. It gives a definition of engineered bamboo (glubam) in an analogy with steel structures and wood structures. Structural systems and components have been designed using glubam; then industrialized production processes of glubam are described. Based on state-of-the-art research, design guidelines are suggested, in a comparable and parallel approach to the existing guidelines for composite wood structures. The book also discusses bamboo structures in the context of sustainable development, including the benefits of using bamboo as an alternative or replacement for wood, especially for developing countries, many of which are faced with the lack or destruction of forest resources.

This book contains the contributions from the RILEM International Symposium on Materials and Joints in Timber Structures that was held in Stuttgart, Germany from October 8 to 10, 2013. It covers recent developments in the materials and the joints used in modern timber structures. Regarding basic wooden materials, the contributions highlight the widened spectrum of products comprising cross-laminated timber, glulam and LVL from hardwoods and block glued elements. Timber concrete compounds, cement bonded wood composites and innovative light-weight constructions represent increasingly employed alternatives for floors, bridges and facades. With regard to jointing technologies, considerable advances in both mechanical connections and glued joints are presented. Self-tapping screws have created unprecedented options for reliable, strong as well as ductile joints and reinforcement technologies. Regarding adhesives, which constitute the basis of the jointing/laminating technology of modern timber products, extended options for tailor-made bonding solutions have to be stated. Apart from melamine-urea and phenolic-resorcinol adhesives, one-component-polyurethanes, emulsion isocyanate polymers and epoxies offer a wide range of possibilities. The contributions dealing with experimental and numerical investigations on static, cyclic and seismic behavior of structures clearly reveal the enhanced potential of modern timber construction for reliable and sustainable buildings and bridges of the new millennium. The book is structured in nine thematic areas, being I) Structures II) Mechanical Connections III) Glued Joints and Adhesives IV) Timber and Concrete/Cement/Polymer Composites V) Cyclic, Seismic Behavior VI) Hardwood, Modified Wood and Bamboo VII) Cross-Laminated Timber VIII) Properties and Testing of Wood IX) Glulam
