Perhaps the first book on this topic in more than 50 years, Design of Modern Steel Railway Bridges focuses not only on new steel superstructures but also outlines principles and methods that are useful for the maintenance and rehabilitation of existing steel railway bridges. It complements the recommended practices of the American Railway Engineering and Maintenance-of-way Association (AREMA), in particular Chapter 15-Steel Structures in AREMA’s Manual for Railway Engineering (MRE). The book has been carefully designed to remain valid through many editions of the MRE. After covering the basics, the author examines the methods for analysis and design of modern steel railway bridges. He details the history of steel railway bridges in the development of transportation systems, discusses modern materials, and presents an extensive treatment of railway bridge loads and moving load analysis. He then outlines the design of steel structural members and connections in accordance with AREMA recommended practice, demonstrating the concepts with worked examples. Topics include: A history of iron and steel railway bridges Engineering properties of structural steel typically used in modern steel railway bridge design and fabrication Planning and preliminary design Loads and forces on railway superstructures Criteria for the maximum effects from moving loads and their use in developing design live loads Design of axial and flexural members Combinations of forces on steel railway superstructures Copiously illustrated with more than 300 figures and charts, the book presents a clear picture of the importance of railway bridges in the national transportation system. A practical reference and learning tool, it provides a fundamental understanding of AREMA recommended practice that enables more effective design.

This English translation of the successful French edition presents the conception and design of steel and steel-concrete composite bridges, from simple beam bridges to cable supported structures. The book focuses primarily on road bridges, emphasizing the basis of their conception and the fundamentals that must be considered to assure structural safety and serviceability, as well as highlighting the necessary design checks. The principles are extended in later chapters to railway bridges as well as bridges for pedestrians and cyclists. Particular attention is paid to consideration of the dynamic performance.

Bridges are great symbols of mankind’s conquest of space. They are a monument to his vision and determination, but these alone are not enough. An appreciation of the mathematical theories underlying bridge design is essential to resist the physical forces of nature and gravity. The object of this book is to explain firstly the nature of the problems associated with the building of bridges with steel as the basic material, and then the theories that are available to tackle them. The book covers: a technological history of the different types of iron and steel bridges the basic properties of steel loads on bridges from either natural or traffic-induced forces the process and aims of design based on limit state and statistical probability concepts buckling behaviour of various components and large-deflection behaviour of components with initial imperfections detailed guidance on the design of plate and box girder bridges together with some design examples The Second Edition includes a completely new chapter on the history and design of cable-stayed bridges, the various types of cable used for them and their method of construction, and it addresses many of the changes introduced in the latest version of the British Standard Design Code for steel bridges, BS 5400: Part 3:2000.

Combining a theoretical background with engineering practice, Design of Steel-Concrete Composite Bridges to Eurocodes covers the conceptual and detailed design of composite bridges in accordance with the Eurocodes. Bridge design is strongly based on prescriptive normative rules regarding loads and their combinations, safety factors, material properties, analysis methods, required verifications, and other issues that are included in the codes. Composite bridges may be designed in accordance with the Eurocodes, which have recently been adopted across the European Union. This book centers on the new design rules incorporated in the EN-versions of the Eurocodes. The book addresses the design for a majority of composite bridge superstructures and guides readers through the selection of appropriate structural bridge systems. It introduces the loads on bridges and their combinations, proposes software supported analysis models, and outlines the required verifications for sections and members at ultimate and serviceability limit states, including fatigue and plate buckling, as well as seismic design of the deck and the bearings. It presents the main types of common composite bridges, discusses structural forms and systems, and describes preliminary design aids and erection methods. It provides information on railway bridges, but through the design examples makes road bridges the focal point. This text includes several design examples within the chapters, explores the structural details, summarizes the relevant design codes, discusses durability issues, presents the properties for structural materials, concentrates on modeling for global analysis, and lays down the rules for the shear connection. It presents fatigue analysis and design, fatigue load models, detail categories, and fatigue verifications for structural steel, reinforcement, concrete, and shear connectors. It also covers structural bearings and dampers, with an emphasis on reinforced elastomeric bearings. The book is appropriate for structural engineering students, bridge designers or practicing engineers converting from other codes to Eurocodes.

Steel-concrete composite bridges outlines the various forms that modern steel-concrete composite bridges take, from simple beam bridges through to arches and trusses and modern cable-stay forms. The author brings together a wide variety of steel-concrete composite bridge types, many of which have not been covered in any existing book or design guide. Outlined within are emerging technologies such as folded plate webs, double composite action and extra-dosed girders, along with design rules for composite action and examples of their use in a wide variety of practical applications. Steel-concrete composite bridges shows how to choose the bridge form and design element sizes to enable the production of accurate drawings and also highlights a wide and full range of examples of the design and construction of this bridge type.

The advantage of steel for long span bridges have been well established for some time. Its advantages for short and medium span bridges are also being seriously looked at now particularly form the standpoint of economy, durability, and ease in maintenance during service life. This book provides the reader with an overall perspective for design and construction of steel bridges, particular from considerations of economy, durability and ease of maintenance during service life. It highlights both theoretical as well as practical aspects which govern the process. Realistic illustrations of practical applications have been used throughout. Starting with a study of the evolution in the design of steel bridges and lessons learnt from some landmark bridge failures, the book discusses basic topics, such as design philosophies, characteristics of steel and loads, before dealing with the various structural arrangements commonly used in modern steel bridges and their selection strategies. Modern systems of connections are discussed at lenght. The book contains several chapters explaining important aspects of fabrication and erection, including methodologies for erection of common steel bridges. Durability, protection against corrosion and post-construction maintenance are discussed in detail. It is expected that the book will provide practical guidelines to students as well as engineers and designers in industry for achieving economy, durability and ease in maintenance.

Many old riveted railway bridges are replaced too soon due to a general lack of knowledge about the expected life span. This indicates the need for more information on fatigue and brittle fracture of riveted bridges. This book unveils extensive research and literature results on riveted bridges' fatigue live and shows how to take fatigue properly into account when deciding about the future service life of a riveted railway bridge. It deals with the expected fatigue live, level of stress ranges by traffic, effect of temperature and ageing, loading histories, crack detection, loose rivets, other defects, repair and strengthening, providing proper instructions and more. Intended for structural, bridge and steel construction engineers.
