Covers current design techniques for both allowable stress and new load and resistance factor design (LRFD) approaches recommended by the forthcoming American Association of State Highway and Transportation Officials draft specifications. Addresses the need for repair or replacement of 225,000 U.S. highway bridges as well as the need for 70,000 new bridges in the next 15 years.
A comprehensive guide to bridge design for practicing civil engineers, combining traditional design methods with modern techniques to provide viable, alternative design approaches that can be used to ensure safe and economical bridges. A main feature is the introduction to the LRFD specifications, developed from research requested by AASHTO and initiated by the NCHRP. This document, still under development, addresses load models and load factors, nominal resistance and resistance factors, structural analysis, concrete and steel structures, decks and deck systems, and bridge substructure elements and foundations.
