IMPROVED SEISMIC DESIGN CRITERIA FOR CALIFORNIA BRIDGES: PROVISIONAL RECOMMENDATIONS

This report recommends revisions to the California Department of Transportation (Caltrans) seismic design standards, performance criteria, specifications and practices. It is based on recent research in the field of bridge seismic design and the performance of Caltrans designed bridges in the 1989 Loma Prieta and other recent California earthquakes. Specifically, the report provides recommended revisions to Caltrans current Bridge Design Specifications (BDS) pertaining to seismic loading, structural response analysis, and component design. Special attention is given to design issues related to reinforced concrete components, steel components, foundations, and conventional bearings.
