Book excerpt: Alternate Load Factor (Autostress) Design is a limit-states design of State Highway and Transportation Officials (AASHTO) that was adopted in 1986 in the form of a guide specification for the design of continuous steel-beam bridges using braced compact sections. This approach introduces the inelastic-design concepts of shakedown at overload and mechanism analysis at maximum load in order to approximate more closely the way a continuous structure actually behaves at higher load levels. As a result, a designer has more freedom to choose the distribution of material along the length of a member and thereby to minimize fabrication costs. The guide specification can be used for the economical design of steel bridges using braced compact rolled- or welded-beam sections in continuous spans up to about 130 feet. As part of an ongoing research effort to extend inelastic-design procedures to longer-span girders, a new unified analysis approach was developed that can be applied throughout all the span ranges. The unified approach can be applied to determine moments and corresponding plastic rotations at both overload and maximum load. The approach is founded on classical indeterminate analysis theory and is readily adaptable to computer programming. By effectively reducing costs and representing actual behaviour more closely, the Alternate Load Factor procedures have the potential to influence the next generation of continuous steel-bridge designs markedly. For the covering abstract of the Conference see IRRD Abstract No. 807839.

Available in PDF, EPUB and Kindle. Book excerpt: Design, rehabilitate, and maintain modern highway bridges. From steel and reinforced concrete design, to highway layout and basic geometrics, to geotechnical engineering and hydraulics, Demetrios E. Tonia's Bridge Engineering: Design, Rehabilitation, and Maintenance of Modern Highway Bridges fully integrates the resources you need to master the entire bridge-design process. Written with unusual clarity--and packed with timely design examples and case studies plus eye-opening sidebars and graphics--it shows you how to: understand bridge structures, functions, types, and applications; design superstructures and substructures for maximum maintainability; design highway components--approach pavements and slabs, structure geometrics and elevations, roadway alignments, and more; kick off the project--from funding to site surveying and coring; manage the design process--contract documents, reports, plans, client interactions, and more; manage the bridge itself--from creating a structure inventory to extending GIS and CADD functionality.

This book was released on 1997 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to state department of transportation bridge design and structural engineers, bridge consultants, and others involved in applied and research methods for increasing the live load capacity of existing highway bridges. The synthesis describes the current state of the practice for the various methods used to increase the live load capacity of existing highway bridges. This is done predominantly for bridges in the short- to medium-span range. Information on the more common bridge material types is presented. There is an emphasis on superstructure rather than substructure strengthening.
