Relevant advances have been accomplished by the scientific community and engineering profession in the design, assessment, monitoring, maintenance, and management of sustainable and resilient bridge structures and infrastructures. These advances have been presented and discussed at The Sixth International Conference on Bridge Maintenance, Safety And Management (IABMAS 2012), held in Stresa, Italy, from 8 to 11 July 2012 (http://www.iabmas2012.org). IABMAS 2012 has been organised on behalf of the International Association for Bridge Maintenance And Safety (IABMAS) under the auspices of Politecnico di Milano. This book collects the extended versions of selected papers presented at IABMAS 2012 and invited papers originally published in a Special Issue of Structure and Infrastructure Engineering. These papers provide significant contributions to the process of making more rational decisions in bridge design, assessment, monitoring and maintenance. The editors would like to thank the authors for their contributions and hope that this collection of papers will represent a valuable reference for scientific research and engineering applications in the fields of design, assessment, monitoring, and maintenance of bridges and infrastructure networks.

The covered bridge has long been a symbol of Indiana's past, evoking feelings of romance and nostalgia. These feats of engineering span the rivers and streams that crisscross the county. Jeremy Boshears' photographs capture the beauty of the bridges dotting the riverbanks of Monroe County. With 121 color photographs, The Covered Bridges of Monroe County will appeal to everyone who treasures these iconic structures.

Throughout history, the need to cross the changing British landscape has always driven innovation. Natural valleys, rivers and mountainous features required the construction of bridges in ancient times to expand our horizons, transport goods and, ultimately, conquer all corners of our island nation. Since then, with the development of technology, bridges have become not only practical structures for people and their possessions, but also prominent icons of our railway network, our reliance on motor vehicles and a desire to connect the country's settlements and communities with one another. Today, Britain has bridges spanning not only many of its rivers, but much of its history. Each age brought new designs and engineering prowess, celebrated most proudly during the Industrial Revolution. This book admires some of the best, from the world-renowned to the minor and the modest.

The State of New York is now building one of the world's longest, widest, and most expensive bridges - the new Tappan Zee Bridge - stretching more than three miles across the Hudson River, approximately thirteen miles north of New York City. In Politics Across the Hudson, urban planner Philip Plotch offers a behind-the-scenes look at three decades of contentious planning and politics centered around this bridge. He reveals valuable lessons for those trying to tackle complex public policies while also confirming our worst fears about government dysfunction. Drawing on his extensive experience planning megaprojects, interviews with more than a hundred key figures - including governors, agency heads, engineers, civic advocates, and business leaders - and extraordinary access to internal government records, Plotch tells a compelling story of high-stakes battles between powerful players in the public, private, and civic sectors. He reveals how state officials abandoned viable options, squandered hundreds of millions of dollars, forfeited more than three billion dollars in federal funds, and missed out on important opportunities. Faced with the public's unrealistic expectations, no one could identify a practical solution to a vexing problem, a dilemma that led three governors to study various alternatives rather than disappoint key constituencies. Politics Across the Hudson continues where Robert Caro's The Power Broker left off and illuminates the power struggles involved in building New York's first major new bridge since the Robert Moses era. Plotch describes how one governor, Andrew Cuomo, shrewdly overcame the seemingly insurmountable obstacles of onerous environmental regulations, vehement community opposition, insufficient funding, interagency battles, and overly optimistic expectations.

This book presents 108 canyon bridges that best represent the highest level of bridge construction in China and is divided into four chapters including suspension bridge, cable-stayed bridge, arch bridge and beam bridge. It introduces the definition of canyon bridge for the first time and gives an overview of each bridge's structural characteristics, design and construction techniques, as well as management and maintenance measures. Furthermore, this book provides elevation layout drawings and real view pictures. Chinese version of this book was awarded "Fan Lichu Book Prize" by Bridge and Structure Committee of China Civil Engineering Society in August 2020. It is the first book accounting of canyon bridges and appeals to a wide readership, from bridge designers and engineers to the general public who has interests to learn bridge construction in mountainous areas.

Concrete remains the most common material for bridge construction around the world, and prestressed concrete is frequently the material of choice. Extensively illustrated throughout, this invaluable book brings together all aspects of designing prestressed concrete bridge decks into one comprehensive volume. Commonly used for bridges with spans between 25m and 450m, prestressed concrete bridges provide economic, durable and aesthetic solutions in most situations. This book clearly explains the principles behind the design and construction of prestressed concrete bridges and illustrates the interaction between the two. All the different types of deck arrangement and the construction techniques used are covered. The design aspects, along with the general analysis and design process, of the different types of deck are included with examples. Detailed descriptions of the prestressing components and systems used are also given. The second edition has been updated for the move to Eurocodes and the content expanded in areas, such as: the inspection, maintenance and demolition of prestressed concrete bridges; integral bridges; temporary works and construction requirements.

In recent years, integral bridges have become increasingly popular in the UK. The Highways Agency standard now requires, where possible, that all new bridges with a length of less than sixty metres should be of integral form. In addition, it has been found that, due especially to the problems and costs associated with failed expansion joints, integral bridges are not only cost effective but also have a longer lifespan. Integral Bridges was commissioned by the Highways Agency to produce guidance for bridge designers by addressing the thermally induced soil/structure interaction problem created by environmental changes of temperature and the associated cyclical displacements imposed on the granular backfill to the bridge abutments. It develops a better theoretical understanding of the cyclic performance, in particular the strain racheting in the backfill soil when in contact with a stiff structure. It also identifies the governing soil parameters and examines their influence in the interaction problem, develops numerical modelling procedures to predict interactive soil behaviour, and identifies and quantifies the controlling features of bridge structures relevant to the interaction problem.

In the twentieth century bridge engineers have seen many changes. Advances in technology, materials and engineers understanding of structural behaviour and methods of analysis has presented opportunities for innovation and have led to increasingly sophisticated solutions to the basic problem of providing a bridge over an obstacle. However, despite these innovative technological changes, the masonry arch bridge has shown itself to be a durable, cost-effective structure, tolerant of its modern environment and out-performing many of its competitors.

Because of their structural simplicity, bridges tend to be particularly vulnerable to damage and even collapse when subjected to earthquakes or other forms of seismic activity. Recent earthquakes, such as the ones in Kobe, Japan, and Oakland, California, have led to a heightened awareness of seismic risk and have revolutionized bridge design and retrofit philosophies.

In Seismic Design and Retrofit of Bridges, three of the world's top authorities on the subject have collaborated to produce the most exhaustive reference on seismic bridge design currently available. Following a detailed examination of the seismic effects of actual earthquakes on local area bridges, the authors demonstrate design strategies that will make these and similar structures optimally resistant to the damaging effects of future seismic disturbances.

Relying heavily on worldwide research associated with recent quakes, Seismic Design and Retrofit of Bridges begins with an in-depth treatment of seismic design philosophy as it applies to bridges. The authors then describe the various geotechnical considerations specific to bridge design, such as soil-structure interaction and traveling wave effects. Subsequent chapters cover conceptual and actual design of various bridge superstructures, and modeling and analysis of these structures.

As the basis for their design strategies, the authors' focus is on the widely accepted capacity design approach, in which particularly vulnerable locations of potentially inelastic flexural deformation are identified and strengthened to accommodate a greater degree of stress. The text illustrates how accurate application of the capacity design philosophy to the design of new bridges results in structures that can be expected to survive most earthquakes with only minor, repairable damage.

Because the majority of today's bridges were built before the capacity design approach was understood, the authors also devote several chapters to the seismic assessment of existing bridges, with the aim of designing and implementing retrofit measures to protect them against the damaging effects of future earthquakes. These retrofitting techniques, though not considered appropriate in the design of new bridges, are given considerable emphasis, since they currently offer the best solution for the preservation of these vital and often historically valued thoroughfares.

Practical and applications-oriented, Seismic Design and Retrofit of Bridges is enhanced with over 300 photos and line drawings to illustrate key concepts and detailed design procedures. As the only text currently available on the vital topic of seismic bridge design, it provides an indispensable reference for civil, structural, and geotechnical engineers, as well as students in related engineering courses.

The results obtained are compared with numerical simulations and analytical calculations. The book also contains some information on testing the materials of steel and concrete and their characteristics. Finally, a variety of types of composite action between steel and concrete have been examined and are discussed.

Michigan's location among the Great Lakes has positioned it at the crossroads of many worlds. Its first hunters arrived ten thousand years ago, its first farmers arrived about six thousand years after that, and three hundred years ago the French expanded into the territory. This book is a small sample of the words of Michigan's people - a collection of stories, letters, diary entries, news reports, and other documents - that give personal insights into important aspects of Michigan's history. Designed to provoke thought and discussion about Michigan's past, the documents in this reader are expressions of past ideas, markers of change, and windows into the lives of the people who lived during well-known events in Michigan history.

The second edition of the bestselling Steel-concrete Composite Bridges is fully up-to-date with the methods now used for these structures in accordance with Eurocodes, introduced since publication of the first edition. This book shows how to design the various forms of steel-concrete composite bridges simply, with the use of real-life illustrative examples of bridges and data from research. Steel-concrete composite bridges are those that combine both steel and concrete elements. They are a commonly-used and economical option for modern bridge construction projects. Knowledge of both materials and the behaviour of the interface between them is required for design of steel-concrete composite bridges, and is an essential part of the engineer's knowledge set. This new edition provides a general introduction to the relevant Eurocodes and covers EC1 on loadings (particularly for bridge loads), EC2 for concrete elements, EC3 for steel (with particular reference to the material properties and buckling) and EC4 for composite action and many industry examples and case studies.

Analysing beam bridges, arch bridges and cable-stayed bridges, the second edition of Bridge Launching outlines key methods for the structural analysis of launched bridges, and provides best practice advice to address time-dependent effects and the buckling of steel girders. Bridge design and construction are thoroughly explored, together with special launch bearings and systems, nose-deck interaction, the loading of temporary and final piers, field monitoring, and data acquisition techniques. Process simulation techniques for optimisation of deck casting are also covered.

Most people remember the flooding of Cork in 2009 and the tremendous damage that was caused. Less well-known is that this was not the first time this had happened. On 1 November 1853 another flood of immense proportions poured into the city from the west. On that occasion the main bridge in the city, St Patrick's Bridge, was swept away and with it the lives of between fifteen and twenty people. Where Bridges Stand: The River Lee Bridges of Cork City tells the story of how the city grew around, and in harmony with, the bridges that span the twin channels of the River Lee, the people and the historical contexts associated with the building projects that saw Cork grow from a medieval walled town to the thriving commercial port and modern city that it is today.

A celebration of the life and engineering achievements of Isambard Kingdom Brunel by two of the world's foremost authorities. In his lifetime, Isambard Kingdom Brunel towered over his profession. Today, he remains the most famous engineer in history, the epitome of the volcanic creative forces which brought about the Industrial Revolution - and brought modern society into being. Brunel's extraordinary talents were drawn out by some remarkable opportunities - above all his appointment as engineer to the new Great Western Railway at the age of 26 - but it was his nature to take nothing for granted, and to look at every project, whether it was the longest railway yet planned, or the largest ship ever imagined, from first principles. A hard taskmaster to those who served him, he ultimately sacrificed his own life to his work in his tragically early death at the age of 53. His legacy, though, is all around us, in the railways and bridges that he personally designed, and in his wider influence. This fascinating new book draws on Brunel's own diaries, letters and sketchbooks to understand his life, times, and work.

Originally published in 1934, this book was written by the renowned British civil engineer Sir Charles Inglis (1875-1952), inventor of the Inglis Bridge and head of the Cambridge University Engineering Department from 1919 to 1943. The text presents a study of 'the dynamic effects in railway bridges, produced by the action of locomotives and other moving loads, and the determination of simple, yet scientific formulae, whereby these effects can be predicted with a reasonable degree of accuracy'. This book will be of value to anyone with an interest in railway bridges and the history of civil engineering.

The construction of bridges in Britain and Ireland during the period of 1735 1835 was marked by important technical developments and the introduction of new materials. This book is a comprehensive history of bridge building during the century, treating the administration and financing of projects as well as the designs and methods of construction. All the bridges described are of interest as engineering works; as architecture some are unimportant but many achieved real grandeur and beauty. The book is based on exhaustive study of primary sources which are fully documented, but it is a highly readable account. More than half of it consists of narratives of individual bridge projects, in which all the men involved, from noblemen and generals to country masons and carpenters, come alive for the reader. Much of the detail of these stories has never been published before. Among the topics which can be traced through the narratives are the growth in spans and changes in the proportions of bridges, the borrowing and modification of Continental styles, a halting progress towards the use of scientific theory in bridge design, the introduction of iron arches and the important role played by 'amateurs', including Tom Paine and Samuel Johnson. Over 200 illustrations accompany the text.

Covering a wide range of structural elements and related defects, this collection of twenty concrete bridge strengthening and repair case studies showcases solutions to real problems encountered in the field and the processes by which those solutions were developed. Drawing on a lifetime of experience Atkins consultant Iain Kennedy Reid provides insight into methods of investigation and diagnosis of problems relating to beams, slabs, columns and panel walls, as well as how to apply demand-led research to these problems in a practical way.

Stress Ribbon and Cable-Supported Pedestrian Bridges considers how slender concrete decks are used in the design of suspension and cable stayed structures. It looks at their characteristic feature - their rigidity, which is mainly given by the tension stiffness of prestressed concrete decking, so much so that movement caused by pedestrians or wind does not register as discomfort by users. Starting with a brief history this book describes structural types, addresses general design criteria, current technology, static and dynamic analysis and discusses the results of the static and dynamic loading tests. Illustrated throughout, Stress Ribbon and Cable-Supported Pedestrian Bridges provides numerous international examples and case studies of outstanding structures. This new edition has been fully updated to bring text in to line with Eurocodes and includes new examples and case studies to showcase the advances in design techniques and testing.

Since opening in 1931, the George Washington Bridge, linking New York and New Jersey, has become the busiest bridge in the world, with 103 million vehicles crossing it in 2016. Many people also consider it the most beautiful bridge in the world, yet remarkably little has been written about this majestic structure. Intimate and engaging, this revised and expanded edition of Michael Rockland's rich narrative presents perspectives on the GWB, as it is often called, that span history, architecture, engineering, transportation, design, the arts, politics, and even post-9/11 mentalities. This new edition brings new insight since its initial publication in 2008, including a new chapter on the infamous 'Bridgegate' Chris Christie-era scandal of 2013, when members of the governor's administration shut down access to the bridge, causing a major traffic jam and scandal and subsequently helping undermine Christie's candidacy for the US presidency. Stunning photos, from when the bridge was built in the late 1920s through the present, are a powerful complement to the bridge's history. Rockland covers the competition between the GWB and the Brooklyn Bridge that parallels the rivalry between New Jersey and New York City. Readers will learn about the Swiss immigrant Othmar Ammann, an unsung hero who designed and built the GWB, and how a lack of funding during the Depression dictated the iconic, uncovered steel beams of its towers, which we admire today. There are chapters discussing accidents on the bridge, such as an airplane crash landing in the westbound lanes and the sad story of suicides off its span; the appearance of the bridge in media and the arts; and Rockland's personal adventures on the bridge, including scaling its massive towers on a cable. Movies, television shows, songs, novels, countless images, and even PlayStation 2 games have aided the GWB in becoming a part of the global popular culture. This tribute will captivate residents living in the shadow of the GWB, the millions who walk, jog, bike, skate, or drive across it, as well as tourists and those who will visit it someday.

The Golden Gate Bridge is one of the most beautiful and most photographed structures in the world. It's also the most deadly. Since it opened in 1937, more than 1,500 people have died jumping off the bridge, making it the top suicide site on earth. It's also the only international landmark without a suicide barrier. Weaving drama, tragedy, and politics against the backdrop of a world-famous city, "The Final Leap" is the first book ever written about Golden Gate Bridge suicides. John Bateson leads us on a fascinating journey that uncovers the reasons for the design decision that led to so many deaths, provides insight into the phenomenon of suicide, and examines arguments for and against a suicide barrier. He tells the stories of those who have died, the few who have survived, and those who have been affected - from loving families to the Coast Guard, from the coroner to suicide prevention advocates.
