Mechanical Connections in Wood Structures


Book Description

This manual presents current design practices and research information on mechanical fasteners used in wood connections in the United States and abroad. Chapters review a vast array of connections, including nails, spikes, and staples; lag screws and wood screws; bolts, drift bolts, and pins; metal connector plates, and timber connectors. Issues addressed range from materials and basic design criteria to fabrication practices, installation practices, connection details and the research basis for design practice.




Materials and Joints in Timber Structures


Book Description

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







Kinetics of Mechanical Connections in Wood Structures


Book Description

As a part of the process of renovation of Eurocode-5, a study on the variables affecting the load bearing capacity and the kinetics of mechanical connections is conducted together with an investigation on the influence of the fiber direction in the embedment strength of wood. Experiments and numerical models are made and a complementary identification of the failure mode is realized. The large amount of variables and cross-correlations affecting the load bearing capacity of the connections as well as the complex effect of the grain direction on the embedment strength of wood, makes indispensable the further study in both subjects. This report provides useful information to help defining future needed experiments.




Timber Connections


Book Description

This book describes the application of mathematical and fundamental theory as stated in the relevant standards, namely EYM and NDS. Timber is one of the important building materials in the field of engineering, other than concrete and steel. However, there is still a lot of unexplored knowledge about timber, including how timber connections are made. One of the main types of timber connection is mortise and tenon. Mortise and tenon are widely seen as one of the most important traditional timber structural joint. In order to understand the load-carrying capacity and performance of the structural mortise and tenon joint, the existing theoretical background of timber joint design is made as a reference. Current equations applicable in estimating the load-carrying capacity of timber joint uses the European Yield Model (EYM). Therefore, the main aim of this book is to share the basic design knowledge, inclusive of safety factor limitations (as engineering main factor) in structural design.

Advanced Timber Structures


Book Description

Wood is usually perceived as a "traditional" material. However, the properties of this material have now for some time made it possible to design free shapes and highly complex structures. Today, the wood laboratory of the EPF Lausanne, which was originally founded by Julius Natterer, is testing the production of origami structures, ribbed shells, fabric structures and curved panels under the guidance of Professor Weinand using digital calculation and computer-aided processing methods. The research results are tested in prototypes, which demonstrate the potential applications in large-scale timber buildings. By exploring the hitherto unused potential of wood as a construction material, this book provides an exciting and inspiring outlook on a new generation of timber buildings.




Timber Engineering


Book Description

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.
