The Seismic Retrofitting Guidelines for Complex Steel Truss Highway Bridges present the state of the practice, through 2005, for retrofitting steel truss bridges in the US. A performance-based seismic retrofit philosophy is used. The guidelines cover all major aspects pertinent to the seismic retrofitting of steel truss bridges, with a focus on superstructure retrofit. Case studies are provided.
These guidelines are a supplement to the 2006 FHWA Seismic Retrofitting Manual for Highway Structures for “unusual or “long span” steel trusses.
