An international team of experts has joined forces to produce the Bridge Engineering Handbook. They address all facets-the planning, design, inspection, construction, and maintenance of a variety of bridge structures-creating a must-have resource for every bridge engineer. This unique, comprehensive reference provides the means to review standard practices and keep abreast of new developments and state-of-the-art practices. Comprising 67 chapters in seven sections, the authors present: Fundamentals: Provides the basic concepts and theory of bridge engineering Superstructure Design: Discusses all types of bridges Substructure Design: Addresses columns, piers, abutments, and foundations Seismic Design: Presents the latest in seismic bridge design Construction and Maintenance: Focuses on the practical issues of bridge structures Special Topics: Offers new and important information and unique solutions Worldwide Practice: Summarizes bridge engineering practices around the world. Discover virtually all you need to know about any type of bridge: Reinforced, Segmental, and Prestressed Concrete Steel beam and plate girder Steel box girder Orthotropic deck Horizontally curved Truss Arch Suspension Cable-stayed Timber Movable Floating Railroad Special attention is given to rehabilitation, retrofit, and maintenance, and the Bridge Engineering Handbook offers over 1,600 tables, charts, and illustrations in ready-to-use format. An abundance of worked-out examples give readers step-by-step design procedures and the section on Worldwide Practice provides a broad and valuable perspective on the "big picture" of bridge engineering.

More than 27,000 trucks were weighed in seven states using a Bridge Weigh-in-Motion system. The system used instrumented highway bridge girders to act as equivalent static scales to obtain truck gross and axle weights, dimensions and speed. Improvements were made in the system software and hardware such that weighing can now be performed automatically with no traffic observer necessary. The weighing operation is undetectable by truck drivers hence the results are not biased due to heavy trucks avoiding the scale. Night weighing has been performed with no danger to crew personnel or highway traffic.

A research project initiated in 1988 focuses on development of loading spectra for railway bridges under current operating conditions. The objectives for the initial three year phase are as follows: 1) develop loading spectra for railway bridges through field measurements of wheel loads on bridges; and 2) conduct detailed measurements of strains and deformations in primary and secondary bridge members under static and impact loads in order to determine the actual distribution of loads in bridges of different types and spans. The first bridge to be studied is a steel plate girder bridge with an open deck. Vertical wheel loads are measured at mid-span of the bridge and on each approach. Lateral wheel loads and flange strains are also measured at mid-span. Loading spectra and bridge response histograms are determined from measured data. Measured and calculated bridge responses are also compared. For the covering abstract of the Conference see IRRD Abstract No. 807839.

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.

There is considerable uncertainty about what level of traffic loading bridges should be designed for. Codes specify notional load models, generally to represent extreme levels of normal traffic, but these are often crude and have inconsistent levels of safety for different load effects. Over the past few decades, increasing quantities of reliable truck weight data has become available and it is now possible to calculate appropriate levels of bridge traffic loading, both for specific bridges and for a road network. Bridge Traffic Loading brings together experts from all over the world to deliver not just the state-of-the-art of vertical loading, but also to provide recommendations of best-practice for all the major challenges in the field – short-span, single and multi-lane bridge loading, dynamic allowance and long-span bridges. It reviews issues that continue to be debated, such as which statistical distribution is most appropriate, whether free-flowing or congested traffic governs and dealing with future traffic growth. Specialist consultants and bridge owners should find this invaluable, as will regulators.
