This is 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.
