- Provides the necessary functional knowledge of the track behaviour, covering the function of the various track components, their interaction as elements of the track system, and the interaction of the systems track and railway vehicles;
- Presents important tools and future challenges for infrastructure managers;
- Supplemented with an historical analysis of railway;
A proper quality of a track and other infrastructure objects represents a basic requirement for train safety and punctuality. Most of the physical systems and their components deteriorate over time. This affects performance and may lead to failures. Albert Einstein said, “You have to learn the rules of the game. And then you have to play better than anyone else.” Only if we understand how the whole system works, taking into account its imperfections and how they influence its quality and performance will we be able to learn the rules of the game and “play better.” The book provides the readers with the necessary functional knowledge of track behaviour and comprehensively covers the function of the various track components, their interaction as elements of the track system, as well as the interaction of the track with railway vehicles. By presenting important tools for a deep understanding of track-behaviour this book aims to be a reference guide for infrastructure managers and to help them to find ways improving track quality for optimum long-term behaviour.

EUROSTEEL 2011, 6th European Conference on Steel and Composite Structures.
According to the traditions, the Conference offers a platform to discuss a wide range of problems related to great variety of research, design and construction activities. We can confidently say that the Eurosteel conferences have developed into one of the most important events for European steel researchers and designers: the Conference in Budapest attracts more than 500 international delegates of structural engineers and research institutes; more than 400 papers from 50 countries around the world are presented. Needless to say, today’s success would have not been achieved without the extensive efforts, contribution and the continuous expansion of the Conferences held earlier in Athens (1995), Prague (1999), Coimbra (2002), Maastricht (2005) and Graz (2008). The proceedings of the Conference include 424 papers in 3 volumes on more than 2500 pages. The contributions cover state-of-the-art of the current activities on steel and composite structures. All papers were reviewed by the Scientific Committee; their voluntary work is gratefully acknowledged.
The Editors wish to express their gratitude to the ECCS, the publisher of the proceedings for the significant financial and technical help for the organizers. The members of the Organizing Committee, an enthusiastic team at the Department of Structural Engineering of BME and a large number of sponsors supported the organization of the Conference what is highly appreciated.

Nanotechnology in eco-efficient construction
Author: Fernando Pacheco-Torgal, Maria Vittoria Diamanti, Ali Nazari and Claes-Goran Granqvist | Size: 12.8 MB | Format:PDF | Quality:Original preprint | Publisher: Woodhead publishing | Year: 2013 | pages: 453 | ISBN: 0857095447
As the environmental impact of existing construction and building materials comes under increasing scrutiny, the search for more eco-efficient solutions has intensified. Nanotechnology offers great potential in this area and is already being widely used to great success. This book is an authoritative guide to the role of nanotechnology in the development of eco-efficient construction materials and sustainable construction.
Following an introduction to the use of nanotechnology in eco-efficient construction materials, part one considers such infrastructural applications as nanoengineered cement-based materials, nanoparticles for high-performance and self-sensing concrete, the use of nanotechnology to improve the bulk and surface properties of steel for structural applications and nanoclay-modified asphalt mixtures and safety issues relating to nanomaterials for construction applications. Part two discusses applications for building energy efficiency, including thin films and nanostructured coatings, switchable glazing technology and third generation photovoltaic (PV) cells, high-performance thermal insulation materials, and silica nanogel for energy-efficient windows. The focus of part is photocatalytic applications; chapters investigate nanoparticles for pollution control, self-cleaning and photosterilization and the role of nanotechnology in manufacturing paints and purifying water for eco-efficient buildings.

Eco-efficient concrete
Author: Joao Labrincha, Fernando Pacheco-Torgal and Said Jalali | Size: 37 MB | Format:PDF | Quality:Unspecified | Publisher: Woodhead Publishing | Year: 2013 | pages: 624 | ISBN: 9780857094247
Concrete is one of the most widely-used of all materials with a significant environmental impact. This important book reviews the wealth of recent research on developing more eco-efficient concrete. The editors have compiled contributions from an international group of authors which review a wide range of technologies and strategies. The book presents a very useful input for producing more ecologically friendly concrete. It achieves this goal by dealing with the impact of the concrete from a variety of viewpoints: the concrete constituents themselves, cement and concrete, the concrete as a whole, the application of wastes and by-products, the use of natural materials of low environmental impact, as well as exploring new types of binders.
The opening sections discuss the eco-efficiency and life cycle assessment of Portland cement concrete and consider concrete with supplementary cementitious materials (SCMs). Part three focuses on concrete with non-reactive wastes, including municipal solid waste incinerator (MSWI) concrete, concrete with polymeric, construction and demolition wastes (CDW) and offers an eco-efficient approach to concrete carbonation. The conclusion investigates future alternative binders and the use of nano and biotech in concrete production.

This book focuses on the plastic property of materials, and the way in which structures made of such material behave under load. It is intended for civil, mechanical, electro-mechanical, marine, and aeronautical engineers for under-graduate or post-graduate courses or research, and professionals in industry. Professor Calladine, from long experience in teaching, research and industry, here delivers a readable and authoritative account of theory and applications. He presents the classical "perfect plasticity material" as a model of irreversible mechanical behavior, using this perfect plasticity property to analyze a range of continuum structural problems and metal-forming processes relevant to engineering practice.

The book approaches the basic theory of structures from a different perspective from standard pedagogy. There is consideration of work and energy concepts as fundamental and the equations of statics derived from them. Likewise, these concepts, together with that of the characteristic response, are used in the derivation of beam theory. Plane sections remaining plane is then seen as a particular result for isotropic, homogeneous, prismatic beams. The general theory may still be used where none of these conditions holds, and can even be applied to trusses. It also corrects errors in the theory of beam shear. Special topics discussed include non-uniform torsion, the exact analysis of shear, anisotropy, advanced energy methods, optimum structures, and regular frames. Software provided in the book includes seven general purpose programs for analysis of plane, space frames with rigid or pinned joints, and uses the augmented Gaussian elimination process and dynamic storage techniques.

This book was written to provide a quick guide to welding inspection that is easy to read and understand. It is difficult to find books specifically covering weld inspection requirements. This book will give you a basic understanding of the subject and so help you decide if you need to look further. In many cases the depth of knowledge required for any particular welding-related subject will be dependent on specific industry requirements. In all situations, however, the welding inspector s role is to ensure that welds have been produced and tested in accordance with the correct code specified procedures and that they are code compliant. Code compliance in this sense means that the weld meets all the requirements of the defect acceptance criteria specified within the code.
