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: Structures, Mechanical Connections, Glued Joints and Adhesives, Timber and Concrete/Cement/Polymer Composites, Cyclic, Seismic Behavior, Hardwood, Modified Wood and Bamboo, Cross-Laminated Timber, Properties and Testing of Wood, Glulam

Geotextile encapsulated sand elements are three-dimensional systems manufactured from textile materials, non-woven materials or combinations of textile and non-woven materials that are filled with sand on-site. These systems are relatively new and the number of applications is growing in river and coastal engineering. Quite often Geosystems are mentioned as a possible solution, but planners, designers and contractors feel rather hesitant about the application of geotextile encapsulated sand elements due to a lack of experience and adequate design rules.

The use of geosystems has the advantage that local material can be applied and that no (expensive) quarry stone needs to be extracted and transported from the mountains to the site. Compared to traditional construction methods (with quarry stone) the application of geotextile sand filled elements may add considerable operational advantages to the execution of marine works and may offer attractive financial opportunities. In the application of geotextile encapsulated sand elements however, proper attention should be paid to the laying down of different responsibilities of the parties in the contract.

In Geosystems. Design Rules and Applications four types of geotextile sand elements are distinguished, each with specific properties: geo-bags, geo-mattresses, geotextile tubes and geotextile containers. The focus is on the use of geosystems filled with sand as a construction in river and coastal engineering. Geosystems filled with sludge are not covered. The chapters “Introduction” and “General design aspects” are followed by four chapters of the same structure dealing with the various systems. Each of these four chapters starts with a general description and applications and ends with a calculation example. Design aspects are dealt with in the remaining paragraphs.

Geosystems. Design Rules and Applications is based on research commissioned by the Dutch Rijkswaterstaat and Delft Cluster. The realisation of the Dutch version was coordinated by a CUR-committee. The English version is a translation of the Dutch version (CUR-publication 217). However, new developments have been added and the text was checked once again and improved. Geosystems. Design Rules and Applications is an essential reference for professionals and academics interested in River and Coastal Engineering, but aims also at those interested in Geotechnical Engineering.

In a rapidly changing world, with increasing competition in all sectors of transportation, railways are in a period of restructuring their management and technology. New methods of organization are introduced, commercial and tariff policies change radically, a more entrepreneurial spirit is required. At the same time, new high-speed tracks are being constructed and old tracks are renewed, high-comfort rolling stock vehicles are being introduced, logistics and combined transport are being developed. Awareness of environmental issues and the search for greater safety give a new role to the railways within the transportation system. Meanwhile, methods of analysis have significantly evolved, principally due to computer applications and new ways of thinking and approaching old problems. Thus, it becomes necessary to come up with a new scientific approach to tackle management and engineering aspects of railways, to understand in-depth the origins and inter-relationships of the various situations and phenomena and to suggest the appropriate methods and solutions to solve the various emerging problems. This book aims to cover the need for a new scientific approach for railways. It is intended to be of use to railway managers, economists and engineers, consulting economists and engineers, students of schools of engineering, transportation, economics, and management. The book is divided into three parts, which deal succes-sively with management, track, and rolling stock, environment and safety.Each chapter of the book contains the necessary theoretical analysis of the phenomena studied, the recommended solutions, applications, charts and design of the specific railway component. In this way, both the requirement for a theoretical analysis is met, and the need of the railway manager and engineer for tables, nomographs, regulations, etc. is satisfied. Railways in Europe have separated activities of infrastructure from those of operation. In other parts of the world, however, railways remain unified. The book addresses both situations (separated and unified railways). Railways present great differences in their technologies. Something may be valid for one such technology, but not for another. To overcome this problem, regulations of the International Union of Railways (UIC) as well as European Standardization (CEN) and European Technical Specifications for Interoperability (TSIs) have been used to the greatest extent possible. Whenever a specific technology or method is presented, the limits of its application are clearly emphasized.

Water in and beneath a road pavement has a major impact on the road's performance and its survivability. This book provides a state-of-the-art on the topic of water in pavements and the adjacent ground. It includes coverage of the basic theory; where the water comes from; how it may (or may not) be drained; the effect of temperature on the movement; how movements may be modelled numerically; and the impact that water content has on pavement material and subgrade behaviour. Sections on instrumentation and monitoring are also provided. With increased concerns that road construction may introduce contaminants into the environment, the book also studies environmental aspects of water in roads and their immediate surroundings by describing the leaching action of pavement water; the opportunities for the pavement to sorb contaminants from pavement run-off; water sampling; and water quality needs. It draws on information from a wide variety of sources, particularly in Europe and the USA, both published and unpublished, having been written by a broad team of practising engineers, hydrogeologists, environmental scientists and researchers. This book is the principal output of a large collaborative study performed as part of the COST programme, managed by the European Science Foundation.

This manual for civil and structural engineers aims to simplify as much as possible a complex subject which is often treated too theoretically, by explaining in a practical way how to provide uncomplicated, buildable and economical foundations.

It explains simply, clearly and with numerous worked examples how economic foundation design is achieved. It deals with both straightforward and difficult sites, following the process through site investigation, foundation selection and, finally, design.

The book includes chapters on many aspects of foundation engineering that most other books avoid including: filled and contaminated sites + mining and other man-made conditions. + features a step-by-step procedure for the design of lightweight and flexible rafts, to fill the gap in guidance in this much neglected, yet extremely economical foundation solution + concentrates on foundations for building structures rather than the larger civil engineering foundationsincludes many innovative and economic solutions developed and used by the authors’ practice but not often covered in other publications + provides an extensive series of appendices as a valuable reference source.

For the Second Edition the chapter on contaminated and derelict sites has been updated to take account of the latest guidelines on the subject, including BS 10175. Elsewhere, throughout the book, references have been updated to take account of the latest technical publications and relevant British Standards.
