The knowledge of the real forces acting on a structure are of great importance in the condition assessment process of existing structures. In this sense, this work provides a novel approach for identification of dynamic moving forces acting on a bridge structure. It seeks to find the optimal time dependent force values that minimize the difference between the computed and measured displacement and acceleration time histories for a limited number of sensor locations. The work also presents extensive experimental investigations of the developed method on real structures in operation, which consistently show that it can be successfully used on a wide range of applications: from small structures excited by rather low pedestrian forces up to the "heavy category" of a complete train passing a railway bridge. In this context, a set of particularities and limitations arising in the practical application of the method on real structures are also discussed.

• (source: Nielsen Book Data)

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.

Vehicle-bridge interaction happens all the time on roadway bridges and this interaction performance carries much useful information. On one hand, while vehicles are traditionally viewed as loads for bridges, they can also be deemed as sensors for bridges' structural response. On the other hand, while bridges are traditionally viewed as carriers for vehicle weight, they can also be deemed as scales that can weigh the vehicle loads. Based on these observations, a broad area of studies based on the vehicle-bridge interaction have been conducted in the authors' research group. Understanding the vehicle and bridge interaction can help develop strategies for bridge condition assessment, bridge design, and bridge maintenance, as well as develop insight for new research needs.This book documents fundamental knowledge, new developments, and state-of-the-art applications related to vehicle-bridge interactions. It thus provides useful information for graduate students and researchers and therefore straddles the gap between theoretical research and practical applications.

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 book discusses design solutions from the authors practical experience and provides insights into conceptual design with concrete, steel or composite bridge solutions as alternatives. Key features: Principal design concepts and analysis are dealt with in a unified approach. Execution methods and evolution of the static scheme during construction are dealt with for steel, concrete and composite bridges. Aesthetics and environmental integration of bridges are considered as an issue for concept design. Bridge analysis, including modelling and detail design aspects, is discussed for different bridge typologies and structural materials. Specific design verification aspects are discussed on the basis of present design rules in Eurocodes. The book is an invaluable guide for postgraduate students studying bridge design, bridge designers and structural engineers.

"Depuis vingt siècles, des bâtisseurs gallo-romains du pont du Gard aux cordées de voltigeurs pendus dans les haubans du viaduc de Millau, la France s'est constituée un patrimoine exceptionnel d'ouvrages d'art, certainement l'un des plus riches au monde. Du ponceau égaré en pleine nature jusqu'au plus prestigieux pont d'apparat de Paris, on ne dénombre pas moins de 250000 ponts aujourd'hui en France! Il n'est donc pas surprenant que cette histoire collective, aux multiples facettes, soit méconnue. Elle est pourtant intimement liée à l'Histoire de France. Un pont se révèle être ainsi un précieux témoin sur l'état de l'art des techniques, mais aussi sur les aspects politiques, sociaux et économiques de son époque. Bien que la connaissance de ces multiples aspects ne soit pas indispensable pour en apprécier le résultat, leur compréhension s'avère précieuse pour satisfaire aussi bien l'oeil que l'esprit sur la solution de franchissement retenue. À quelques exceptions près, les constructeurs restent dans l'anonymat le plus complet. L'un de ces illustres inconnus confessait que si les ingénieurs remplissent aujourd'hui le monde du bruit de leurs travaux, du moins ils ne le fatiguent guère de celui de leur nom. Il ne Faut donc pas oublier que la construction d'un pont reste avant tout une Formidable aventure humaine!"--Page 4 of cover.
