Abstract: This manual collects and summarizes the state-of-the-art practice to date, for retrofitting steel truss bridges on the highway system within the United States. These guidelines are based on and are supplementary to the Seismic Retrofitting Manual for Highway Structures Part 1: Bridges, developed by MCEER, to be published by the Federal Highway Administration (FHWA) in 2006. Seven chapters on the technical application of these guidelines are contained, including an introduction; retrofitting philosophy and process; screening and prioritization; structural analysis; design parameters; evaluation of members, connections and subsystems; and retrofit measures. Three additional chapters provide case studies, a glossary, references, and a bibliography.
