Summary

The up-to-date guide to applying theory and specifications to real-world highway bridge design Design of Highway Bridges, Second Edition offers detailed coverage of engineering basics for the design of short- and medium-span bridges. Based on the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications, it is an excellent engineering resource. This updated edition features: * Expanded coverage of structural analysis, including axle and lane loads, along with new numerical analytic methods and approaches * Dozens of worked problems, primarily in Customary U.S. units, that allow techniques to be applied to real-world problems and design specifications * Revised AASHTO steel bridge design guidelines that reflect the simplified approach for plate girder bridges * The latest information on concrete bridges, including new minimum reinforcement requirements, and unbonded tendon stress at ultimate and losses for prestressed concrete girders * Information on key bridge types, selection principles, and aesthetic issues * Problems and selected references for further study * And more From gaining quick familiarity with the AASHTO LRFD specifications to seeking broader guidance on highway bridge design--this is the one-stop, ready reference that puts information at your fingertips.

Author Biography

RICHARD M. BARKER, PhD, PE, is Professor Emeritus of Civil and Environmental Engineering at Virginia Polytechnic Institute and State University. A consultant to contractors and design firms on bridge-related projects, he has fifty years of experience with highway bridges as a structural designer, project engineer, researcher, and teacher. He served as a subconsultant to AASHTO on maintenance of the LRFD specifications and to the Federal Highway Administration (FHWA) on training course development for LRFD design of highway bridge substructures.

JAY A. PUCKETT, PhD, PE, is the V. O. Smith Professor of Civil and Architectural Engineering and Department Head at the University of Wyoming, and President of Bridge Tech, Inc., a consulting firm that specializes in software development for bridge engineering. With thirty years of experience in bridge research and development, he has developed software for the analysis and rating of bridge systems that is currently in use at over forty transportation agencies. Dr. Puckett is a consultant to AASHTO on their BridgeWare load rating and bridge design software. His research has involved several National Academy NCHRP projects.
