Design Of Modern Steel Highway Bridges

Provides complete, integrated coverage of structural analysis and design of conventional and modern bridges, with appropriate specifications and design examples. Also examines bridge history and development, materials, and loads. Demonstrates design procedures and development, the organization of design computations, and the interpretation of AASHTO design specifications. Includes discussions of substructures, bridge piers, abutments, and bridge rating and repair.

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.

A text/reference book describing the design of many types of concrete highway bridges. Using examples, the text examines the development of all required loads and the associated bridge design specifications. Details working stress and load factor methods. Includes design charts. Illustrates the design of box beam, segmental, T-Beams, prestressed, postensured, and pier beams. Explanations can be applied directly to design problems.

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 text provides an introduction to the theory and practice of designing modern highway bridge superstructures. Beginning with the history of bridges, it describes various types of bridge superstructures, materials of construction, bridge loadings, and analysis techniques for various types.

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.
