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. A state–of–the–art text on earthquake–proof design and retrofit of bridges Seismic Design and Retrofit of Bridges fills the urgent need for a comprehensive and up–to–date text on seismic–ally resistant bridge design. The authors, all recognized leaders in the field, systematically cover all aspects of bridge design related to seismic resistance for both new and existing bridges. ∗ A complete overview of current design philosophy for bridges, with related seismic and geotechnical considerations ∗ Coverage of conceptual design constraints and their relationship to current design alternatives ∗ Modeling and analysis of bridge structures ∗ An exhaustive look at common building materials and their response to seismic activity ∗ A hands–on approach to the capacity design process ∗ Use of isolation and dissipation devices in bridge design ∗ Important coverage of seismic assessment and retrofit design of existing bridges

"Theory and Design of Bridges provides early coverage of the aesthetic and economic factors involved in bridge engineering, the basic principles of effective bridge management, and various design approaches and bridge loads, providing a solid conceptual foundation of bridge response under service conditions and at failure. It then moves on to cover virtually every type of bridge, treating them within the context of a coherent structural framework, including: conventional concrete bridges - emphasizing prestressed concrete as the prevalent form of bridge construction, with coverage of new trends in prestressed applications; steel bridges - ranging from I-beam superstructure systems to horizontally curved systems, with detailed discussion of such key topics as ductility, brittle fracture, redundancy, and fatigue; orthotropic deck bridges - highlighted by practical coverage of the still-effective Pelikan-Esslinger method, first introduced in 1957; segmental concrete bridges - reviewed within the context of the groundbreaking 1989 AASHTO guidelines, which mark a major departure from previous design and construction provisions; trusses, movable bridges, and cable-stayed bridges - including their general features, design approaches, and specific examples; elastic arch bridges - with a special focus on buckling and geometry imperfections and associated stability considerations; special bridges - practical insight into structures characterized by unusual member geometry, structural configurations and combinations, and support conditions.".

Addressed to designers and even more so to owners and project managers, this part is meant as a guide to an efficient selection of designers and contractors, and to the preparation of fair contracts providing high quality at reasonable cost. Clearly, a good design must be paid for at its real cost; economising on the design cost can be extremely counterproductive for the owner when considering the final whole-life cost of the project. In addition, it was considered very important to address the designer’s responsibilities and relations with other participants in large projects, and finally design philosophy itself. Part 2 – Design and construction aspects This more technical part is mainly addressed to bridge designers and devoted to a systematic analysis of structural and constructional bridge concepts. Considering the importance of erection techniques in the development of bridge design, this second part of the guide starts by a description of the different construction methods, their advantages and draw-backs, their particularities and, of course, by defining the domain of their most efficient applications. Another main chapter is devoted to the proper design of cross-sections. And finally, a third main chapter deals in detail with the influence of construction techniques on design.

The bridge engineering industry creates an ever-increasing variation of challenges. This landmark publication brings together all topics which are of interest to bridge engineers around the world in one comprehensive manual, and will quickly establish itself as an invaluable reference work. It not only provides a broad overview of the whole subject of bridge engineering, but also focuses on some of the detailed aspects of analysis, design, construction and maintenance. The Manual of Bridge Engineering will be a definitive text for practising civil and structural engineers in consulting firms and government agencies, bridge contractors, research institutes, universities and colleges - in short, all engineers involved in any aspect of the design, construction and repair, maintenance and refurbishment of bridges. Further details The manual begins with a chapter introducing readers to all of the bridge types encountered in bridge construction, from the simplest beam, through arches, to the more complex cable stayed and suspension bridges, and describes their behaviour in a qualitative manner. The second chapter is devoted to the loads which have to be sustained by bridge structures, and in particular looks at traffic load specifications around the world. It covers the brief history of loading specifications, looks in detail at some current code specifications and makes reference to loads due to wind, temperature, shrinkage and construction. This chapter also introduces the reader to the concepts of load distribution and explains the use of influence lines in bridge design. The middle section of the manual deals with the analysis, design and the construction of the more commonly known bridge types. It discusses the analysis tools normally employed and explains the general design concepts - both globally and locally. Finally, for each particular bridge type, the modern methods of construction are explained. These chapters cover a vast area of work, and provide enough information for the understanding of the design process of many different kinds of bridges. The manual then deals with modern developments in the construction of bridges and the consideration of aluminium, fibre composites, bridge enclosures and intelligent structures. There are also chapters dealing with expansion joints, bearings, parapets, drainage, waterproofing, and substructures. The final chapters cover in some detail those topics akin to bridge management. These are vital for a full appreciation of bridge engineering, and give guidance on what is to be considered once the bridge has been commissioned. The subjects covered include protection of both concrete and steel (also with reference to scour protection), project planning, management systems and strategies, inspection, monitoring, assessment and repair and strengthening.
