Book Description
Excerpt from General Specifications for Iron and Steel Railroad Bridges and Viaducts 1. All parts of the structures shall be of wrought-iron or steel, except tics and guard rails. Cast-iron or steel may be used in the machinery of movable bridges and in special cases for bed-plates. Generally "double tracks through" bridges will have but two trusses, to avoid spreading the tracks at bridges. In calculating strains the length of span shall be understood to be the distance between centres of end pins lor trusses, and between centres of bearing plates for all beams and girders. 3. The girders shall be spaced, with reference to the axis of the bridge, as required by local circumstances, and directed by the Engineer of the Railroad Company. ( 5.) Longitudinal floor girders shall in 110 case be less than three feet and three inches from centre line of tracks. ( 6.) 4. For all through bridges and overhead structures there shall be a clear head-room of 20 feet above the base of the rails.

Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Book Description
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.
