Design Guide For Steel Railway Bridges

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 new edition encompasses current design methods used for steel railway bridges in both SI and Imperial (US Customary) units. It discusses the planning of railway bridges and the appropriate types of bridges based on planning considerations.

Analysis and Design of Railway Bridges brings together the analytical tools and design methods necessary to accurately interpret the complex design requirements in the selection process and construction of robust railway bridges. When designing railway bridges, design engineers must face a number of unique structural challenges such as: dead load of the structure, live loads from the carried, frequency of traffic, and dynamic components of the traffic such as impact, centrifugal, lateral, and longitudinal forces. This means the use of complex modeling tools for the selection of proper design criteria. This reference provides a clear and rigorous exposition of the various codes which govern design including: American Association of State Highway and Transportation Officials, American Railroad Engineering and Maintenance-of-Way Association, Federal Highway Administration and the Eurocode for dynamic factor, dynamic loading and load combinations, bridge parameters, modelling of excitation and dynamic behaviour, and verification for fatigue. Explains codes including: American Association of State Highway and Transportation Officials, American Railroad Engineering and Maintenance-of-Way Association, Federal Highway Administration, and the Eurocode Addresses the unique aspects of railway bridge modeling such as: bridge and train modeling techniques, substructure details, structural steel details, prestressed concrete details, and bridge railing and approach rail details Includes design and analysis methods and calculations as well as applications and solved examples Provides the analytical tools and design methods necessary to interpret complex design requirements

The need for large-scale bridges is constantly growing worldwide, as the expansion of transport infrastructures with rail roads and high-speed lines is an important current task in many regions. This book develops all aspects referring to the structural conceptional design and analysis that are taken into account when planning a bridge or viaduct for a high-speed rail line. That includes the characteristics of the railway traffic such as speeds, actions, limit states, etc., and a detailed analysis of the superstructure of the track with its various components and singular elements. One of the special features of the book is that it not only highlights the bridge typologies and structural components related to the bridge design but also takes into account the issues of the track construction. The design basis, the requirements from different situations, and solutions are given. Special attention is paid to the interactions between the structure and the track and to the dynamic nature of railway actions, studying the dynamic response of the structure and its influence on the behaviour of the track and its components as well as on safety, traffic flow quality, and maintenance needs. The particulars of the design of high-speed rail bridges located in seismic areas are included as well. Numerous examples in all chapters serve the book's character as a useful guide to HSR bridge design, and to prevent typical problems and errors. An appendix with selected HSR bridges built worldwide completes the work. With this work the authors provide first-hand experience gained from many years of planning of completed bridges for high-speed rail lines.
