Besides providing the necessary theoretical concepts for a good understanding, this manual intends to be a supporting tool for practicing engineers. To that end, numerous worked examples are provided throughout the book, concerning the analysis of steel structures and the design of elements under several types of actions. These examples facilitate the application of Eurocode regulations in practice. The second edition contains more worked examples and extended explications on issues like torsion.

RILEM TC 248-MMB was established in 2012 with the main aim to improve and distribute knowledge related to moisture measurement in construction materials in various scientific and industrial applications. Properties and performance of building materials and structures are influenced to a large extent by the moisture conditions in the materials. Obvious examples are heat conductivity, shrinkage and creep, transport properties, most types of deterioration, discoloration etc. For research and applications the moisture conditions must be quantified, by measurements in the laboratory or under field conditions. There is much variation in methods being used, even within the same topic, in different countries, both with regard to materials and to applications. No consensus whatsoever does exist. For the construction industry it is important to be able to quantify the moisture conditions in an accurate way in various applications. This state-of-the-art report is divided into two parts, Principles and Applications, with altogether 28 chapters on various moisture measuring principles and a number of applications.

An Insiders' Guide to Inspecting, Maintaining, and Operating Bridges Suspension bridges are graceful, aesthetic, and iconic structures. Due to their attractiveness and visibility, they are well-known symbols of major cities and countries in the world. They are also essential form of transportation infrastructure built across large bodies of water. Despite being expensive to build, they are economical structures for the lengths they span. They have evolved significantly from the basic concept dating back to 200 BC China through the first design for a bridge resembling a modern suspension bridge, attributed to Fausto Veranzio in 1595, to present day span lengths close to two kilometers. Offers Insight from Bridge Owners across the Globe Many of these bridges carry significant traffic, and their upkeep is very important to maintain transportation mobility. They offer grace and functionality, yet are extremely complex to construct and maintain. Bridge owners spend considerable amount of time and resources to ensure uninterrupted service, safety, and security for users. Inspection, evaluation, maintenance, and rehabilitation have evolved significantly. Modern materials and innovative design and construction practices have been integrated into these bridges to maintain durability and extended service life. Inspection, Evaluation and Maintenance of Suspension Bridges Case Studies gives detailed case studies of the Manhattan, Akashi Kaikyo, Tsing Ma, Storebaelt East, Forth Road, Bronx-Whitestone, George Washington, Angus L. Macdonald, Mid-Hudson, Shantou Bay, and Kingston-Port Ewen Bridges. It is written by the owners and practitioners who strive to cost-effectively manage them, and applies all the inspection, evaluation, and rehabilitation methods discussed in the companion volume to give a comprehensive picture of how suspension bridges are mana

This book is the first to bring together academic and practitioner views of Value for Money (VFM). VFM has been used to assess whether or not an organisation has obtained the maximum benefit within the resources available to it. A concept used by the public sector to assess the benefits of major built environment projects, it has become a major tenet of public private partnerships, capital project infrastructure and civil engineering megaprojects. This book presents and discusses the various debates surrounding the concept of Value for Money. It provides an international perspective on VFM by drawing upon the existing and fast developing body of principles and practices for Capital Build Projects. Readers will gain a level of understanding of the issues involved, the challenges, opportunities and the support mechanisms and protocols required for implementation of VFM in capital building development. Ultimately, the book presents a protocol that has been developed to track and monitor the VFM of a capital project from day 1, an Equilibrium Testing Mechanism (ETM) developed by the authors. This testing mechanism allows each of the parties to a project to monitor their VFM position at any given stage of a project from the beginning to the end of the build stage and beyond as necessary. This book is both a useful reference for researchers and a practical guide for the construction and engineering industry.

The use of modern composite materials in construction offers the structural engineer and designer exciting opportunities for all types of buildings and structures. By far the most commonly used and longest established composite material is the combined use of steel and concrete in the form known in most parts of the world as 'composite construction'. Composite Construction takes a comprehensive look at recent developments in this fast growing area. With each chapter written by an acknowledged expert in the field, this book aims to link physical behaviour, engineering approximation, appropriately applied theoretical concepts and design approaches. Composite Construction is not simply a code commentary, nor does it deal with topics purely in terms of developing theory from first principles. Rather, the emphasis is strongly placed on providing both the practising engineer and the student with an understanding of physical behaviour, and the intelligent application of this knowledge in practice

Poor durability of concrete is a continuing concern to owners of structures and their professional advisors.

Dealing with a wide range of non-metallic materials, this book opens up possibilities of lighter, more durable structures. With contributions from leading international researchers and design engineers, it provides a complete overview of current knowledge on the subject.

A thorough and understandable guide to the properties and design of structural composites. It derives from the author's many years of experience of research, industrial development and teaching.

Sprayed concrete lined (SCL) tunnels are growing rapidly in popularity due to their versatility. The design and construction of both hard rock and soft ground tunnels has been revolutionised by the advent of the SCL method and now the use of permanent sprayed concrete linings has unlocked the true potential of the method to minimise construction costs and times. Yet the complex early age behaviour of the sprayed concrete makes the design difficult and requires a robust management system during construction. Consequently the great advantages of the method must be balanced against the risks, as a few high-profile tunnel collapses have illustrated. Practising engineers on site, in the design office or in client organizations will find this book an excellent introduction. It covers all aspects of SCL tunnelling - from the constituents of sprayed concrete to detailed design and management during construction. Although there is a close interdependence between all the facets of sprayed concrete, few engineers have the right breadth of experience and expertise to cover all of them. This urgently needs to be transferred to the wider engineering community as SCL tunnels play an increasingly important role in the delivery of the underground infrastructure which modern urban life demands. In this second edition, beyond a general updating to reflect new developments, the sections on permanent sprayed concrete, the innovative technology of spray applied waterproofing membranes, fibre reinforcement (both steel and macrosynthetic) and composite lining design have been expanded. Sustainability and environmental impact are addressed in a new section.

This book brings together up to date information from research and practice about the interaction between moisture changes and mechanical loading, which may lead to excessive deflections or joint movements in timber structures. It has important applications in timber engineering, and consequences for national and international structural codes of practice.

This book focuses on two areas of ice technology: the use of ice as a construction material and the problems caused by ice to constructions. In connection with describing past and potential future applications of using ice in construction, a detailed discussion on the mechanical properties of ice is given. A state of the art description on ice-making methods, melt protection, methods and reinforcement of ice with the materials are covered.

Restraint and intrinsic stresses in concrete at early ages are vitally important for concrete structures which must remain free of water-permeable cracks, such as water-retaining structures, tunnel linings, locks and dams. The development of hydration heat, stiffness and strength, also the degree of restraint and, especially for high-strength concrete, non-thermal effects, are decisive for sensitivity to cracking. Determining thses stresses in the laboratory and in construction components has led to a clearer understanding of how they develop and how to optimize mix design, temperature and curing conditions. New testing equipment has enabled the effects of all the important parameters to be qualified and more reliable models for predictiong restraint stresses to be developed. Thermal Cracking in Conrete at Early Ages contains 56 contributions by leading international specialists presented at the RILEM Symposium held in October 1994 at the Technical University of Munich. It will be valuable for construction and site engineers, concrete technologists and scientists.

This new volume, Design and Construction of Laboratory Gas Pipelines: A Practical Reference for Engineers and Professionals, focuses on design and installation of laboratory gas pipelines. It instructs design engineers, laboratory managers, and installation technicians on how to source the information and specifications they require for the design and installation of laboratory gas systems suitable for their intended use. The current use of specifications predominantly taken from medical gas standards for this type of work is not always suitable; these standards are for use with medical grade gases that have a purity level of 99.5%. The purity levels required in laboratories, however, start at 99.9% for general industrial use through to 99.9995% (Ultra High Purity (UHP)) and higher. Regular medical gas standards are also unsuitable for use with the oxidizing, flammable, and, in some instances, toxic gases that are regularly encountered in laboratories. As need for gas purity increases, the methodology used to design a piping system must vary to meet those parameters, and this reference provides the necessary information and resources. There are no comprehensive single sources of technical references currently available in this market, states the author, and the generally supplied specifications provided to the construction industry are usually generic and not specifically targeted for the gases in use. The results provide extremely poor quality designs and, in some instances, unusable systems. With over 40 years of specialization in the industry from project management to systems design, testing, and commissioning of projects with values in excess of $15 million, the author comprehensively fills that gap with this rich resource. Key features * provides information on types of laboratories that use laboratory gases and the equipment needed * explains the various methods of construction and the materials used to ensure that the purity of the gases remains as supplied from the manufacturers * incorporates the design methodology used to meet the various requirements of the laboratory and the information required to ensure that the correct engineering is provided * presents information on the purity levels of the gases and the data on the equipment used for pipelines and compatibility issues * presents an example of a simple laboratory gas specification that provides guidelines on the information necessary to provide a set of design documents

Chloride-induced corrosion is the most important durability issue of reinforced concrete structures, and the prediction and prevention of chloride-induced corrosion has attracted considerable interest all over the world. Given that chloride penetrates through the concrete cover, the issues concerning its transport are crucial. These include testing methods, prediction, and the prevention of ingress. During the transport process, physical and chemical interaction occurs between chloride and cement hydrates, which in turn affects the further transport, so the transport of chloride and these interactions are closely related and underpin our understanding of chloride-induced corrosion in RC structures. This book provides in-depth discussion of chloride transport and its interaction in cement-based materials, and reviews and summarizes the state of the art. The mechanisms and testing methods for chloride transport, chemical interactions of chloride with cement hydrates, chloride binding isotherms, measurement of penetration depths, factors affecting chloride transport, and modeling of chloride transport are discussed in detail. This book serves as a reference for researchers or engineer, and a textbook for graduate students.

Occupational accidents have a massive personal and social cost as well as a major financial cost. The construction industry is one of the most dangerous industries, accounting for around 20-30% of all occupational deaths worldwide. The accompanying financial cost is either absorbed directly or passed on in the form of higher insurance costs. In addition, regulatory bodies have started to impose legal accountability on all the parties along the construction supply chain. OHS is hard to implement. Construction projects are complex, with a fluid workforce, and the regulatory framework is highly elaborate. OHS Electronic Management Systems for Construction presents a theoretical framework which is designed to overcome these difficulties, integrating OHS management in construction using knowledge management and web technologies. This framework is explained in a clear step-by-step way, as are features such as a systematically developed corporate safety memory, and a virtual learning portal to facilitate on-demand safety training. The ultimate aim of this book is to aid the development of an established safety culture at the organisational level, and the formation of an industry-wide community of safety practice. This is essential reading for OHS professionals and construction managers attempting to change their industry for the better, as well as advanced students and researchers.

Among all building materials, concrete is the most commonly used-and there is a staggering demand for it. However, as we strive to build taller structures with improved seismic resistance or durable pavement with an indefinite service life, we require materials with better performance than the conventional materials used today. Considering the enormous investment in public infrastructure and society's need to sustain it, the need for new and innovative materials for the repair and rehabilitation of civil infrastructure becomes more evident. These improved properties may be defined in terms of carbon footprint, life-cycle cost, durability, corrosion resistance, strength, ductility, and stiffness. Addressing recent trends and future directions, Mechanics of Fiber and Textile Reinforced Cement Composites presents new opportunities for developing innovative and cost-effective materials and techniques in cement and concrete composites manufacturing, testing, and design. The book offers mathematical models, experimental results, and computational algorithms for efficient designs with fiber and textile reinforced composite systems. It explores alternative solutions using blended cements, innovative reinforcing systems, natural fibers, experimental characterization of key parameters used for design, and optimized designs. Each chapter begins with a detailed introduction, supplies a thorough overview of the existing literature, and sets forth the reasoning behind the experimentation and theory. Documenting the composite action of fibers and textiles, the book develops and explains methods for manufacturing and testing cement composites. Methods to design and analyze structures for reduced weight, increased durability, and minimization of cement use are also examined. The book demonstrates that using a higher volume fraction of fiber systems can result in composites that are quasi-elastic plastic. Speaking to the need to

Post-tensioning is the most versatile form of pre-stressing, a technique which enables engineers to make the most effective use of the material properties of concrete, and so to design structural elements which are strong, slender and efficient. Design in post-tensioned concrete is not difficult and, if done properly, can contribute significantly to the economy and the aesthetic qualities of a building. Post-tensioned floors have found widespread use in office buildings and car park structures, and are also frequently employed in warehouses and public buildings. However, in spite of this, most prestressed concrete texts devote comparatively little attention to floors, concentrating instead on beam elements. This book answers the need for a comprehensive treatment of post-tensioned floor design.

Procurement Systems details the whole spectrum of procurement issues in the construction industry, starting with the client /customer and running through managerial, cultural and IT-based issues. The book commences with an overveiw of previous work and a section on selection criteria is provided to enable practitioners to make their choices of procurement form. Importantly, perfromance comparisons of different procurement forms are discussed and the main emphasis of the book is to highlight best practice based on the most up-to-date research. One chapter deals specifically with developmentally orientated procurement issues in NICs (newly industrialised countries), where best practice is assessed from a different set of perspectives. The authors contributing to this book are among the most highly respected and eminent in the field.

A growing number of urban inhabitants are aware of pressing environmental concerns. This book aims to provide information about relevant environmental quality criteria in urban construction settings, before methods are proposed for assessing these criteria. These will be extremely helpful to eco-building designs, commencing from the very early stages of a project (site selection, program, architectural designs) to the detailed design, construction and management of buildings. The book covers eco-technologies in the field of energy and water conservation, renewable energy, waste management and environmentally-friendly materials, but does not lose sight of comfort and health aspects.

Structures placed on hillsides often present a number of challenges and a limited number of economical choices for site design. An option sometimes employed is to use the building frame as a retaining element, comprising a Rigidly Framed Earth Retaining Structure (RFERS). The relationship between temperature and earth pressure acting on RFERS, is explored in this monograph through a 4.5 year monitoring program of a heavily instrumented in service structure. The data indicated that the coefficient of earth pressure behind the monitored RFERS had a strong linear correlation with temperature. The study also revealed that thermal cycles, rather than lateral earth pressure, were the cause of failure in many structural elements.

The book demonstrates that depending on the relative stiffness of the retained soil mass and that of the structural frame, the developed lateral earth pressure, during thermal expansion, can reach magnitudes several times larger than those determined using classical earth pressure theories. Additionally, a nearly perpetual lateral displacement away from the retained soil mass may occur at the free end of the RFERS leading to unacceptable serviceability problems.These results suggest that reinforced concrete structures designed for the flexural stresses imposed by the backfill soil will be inadequately reinforced to resist stresses produced during the expansion cycles.

Parametric studies of single and multi-story RFERS with varying geometries and properties are also presented to investigate the effects of structural stiffness on the displacement of RFERS and the lateral earth pressure developed in the soil mass. These studies can aid the reader in selecting appropriate values of lateral earth pressure for the design of RFERS. Finally, simplified closed form equations that can be used to predict the lateral drift of RFERS are presented.

While there are many historical examples of successful naturally ventilated buildings, standards for indoor climate have tended to emphasise active, mechanical airflow systems rather than passive natural systems. Despite its importance, knowledge about the performance of naturally ventilated buildings has remained comparatively sparse. With ten key research papers this book seeks to address this lack of information.
