Seismic Retrofitting Manual for Highway Structures:

Part 1 - Bridges

Ian G. Buckle (Lead Author), Ian Friedland, John Mander, Geoffrey Martin, Richard Nutt and Maurice Power

Part 1 provides procedures for screening, evaluation, and retrofitting highway bridges. The manual introduces a performance-based retrofit philosophy similar to that used for the performance-based design of new buildings and bridges.  It extends the guidance provided in the earlier FHWA manuals (originally issued 1983 and updated in 1995), based on recent experiences in California, Japan, and other countries, as well as the results of comprehensive research programs that have been sponsored by FHWA, MCEER, Caltrans, and other agencies.

Part 2 - Retaining Structures, Slopes, Tunnels, Culverts and Roadways

Maurice Power (Lead Author), Kenneth Fishman, Faiz Makdisi, Samuel Musser, Rowland Richards and
T. Leslie Youd

Part 2 includes new procedures for determining the seismic vulnerability of other important highway system structures, namely, retaining structures, slopes, tunnels, culverts, and roadways.  Guidance is provided on screening for potential seismic vulnerabilities; conducting a detailed evaluation; and describing strategies for retrofit design.  In addition, discussion is provided for classifying each structure by type, construction, or expected performance.

Parts 1 and 2 are also available on one CD
