We have included below some examples of steel bridge types and applications but full details can be found under our dedicated Steel Bridges site or alternatively contact us directly. These bridges can carry main road traffic and incorporate 2-lane carriageways, crash barriers and walkways. The effective span of these bridges can range between 15m and m and more detailed information can be found under Highway Bridges on our Steel Bridges website.
John F. Unsworth is a professional engineer PEng. Since his completion of a bachelor of engineering degree in civil engineering and a master of engineering degree in structural engineering, he has held professional engineering and management positions concerning the track, bridge, and structures maintenance, design, and construction at the Canadian Pacific Railway. He is a licensed professional engineer in six Canadian provinces. The first edition of this book provided nine chapters with a focus on the design of new steel superstructures for modern railway bridges referencing the recommended practices of Chapter 15— Steel Structures in the edition of the American Railway Engineering and Maintenance-of-way Association AREMA Manual for Railway Engineering MRE. This second edition updates the first edition by including changes precipitated by subsequent revisions to Chapter 15 of the MRE and the many valuable comments received from steel railway bridge design engineers, fabricators, students, academics, and researchers.
Most curricular materials in TeachEngineering are hierarchically organized; i. Some activities or lessons, however, were developed to stand alone, and hence, they might not conform to this strict hierarchy. Related Curriculum shows how the document you are currently viewing fits into this hierarchy of curricular materials. A concrete bridge in Dallas, TX. Engineers who design structures must completely understand the problem to be solved, which includes the complexities of the site and the customer needs. To design for safety and longevity, engineers consider the different types of loads, how they are applied and where. Engineers often aim for a design that is strongest and lightest possible—one with the highest strength-to-weight ratio.

Bridges were virtually located in Mexico, and so the vehicular live loads, earthquake loads due to local seismicity, and other local loads were adapted in the design. A realistic condition of the local design truck for Mexico was selected from survey traffic flows reported for local highways. Nonlinear dynamic analyses were carried out using seven historical records associated with the largest vertical intensities from subduction earthquakes in Mexico. This research pretends to provide design recommendations for short-span steel bridges in Mexico, in particular for those related to the influence of local seismicity and overloaded vehicular loading in local highways.
The horizontally curved composite girder bridges have excellent properties, such as quick construction, good seismic performance, saving construction formwork and convenience in spatial arrangement. The objective of this paper is to provide and summarize important references related to the analysis, design and construction of curved composite girder bridges. Subjects discussed in this review include 1 different curved girder bridge configurations and their applied range; 2 current specifications; 3 construction issues; 4 design methods; 5 analytical methods; 6 load distribution; 7 torsional behavior; 8 warping stresses; 9 stability; 10 ultimate load-carrying capacity; 11 dynamic and seismic response; 12 loading test; 13 long-term behavior; and 14 design details. The literature survey presented herein mainly focuses on papers written in English, Japanese and Chinese in relation to curved composite girders.

Results achieved from the strength and serviceability limit states indicate that the design of the steel plate girders is controlled by the gravity load combination, rather than the combination with both horizontal and vertical ground motion records.
It has evolved through the acceptance of well-established practices, codes and construction techniques. In fact, when new materials or methodologies are brought to the market, it often takes many years for the techniques to gain inclusion in the modern practice of bridge design.
