This report contains the findings of a study to develop recommended specifications for the seismic design of highway bridges. The objective of this research was to enhance safety and economy through the development of new load and resistance factor design (LRFD) specifications and commentary for the seismic design of bridges. The research considered design philosophy and performance criteria, seismic loads and site effects, analysis and modeling, and design requirements. The specifications are nationally applicable with provisions for all seismic zones and are intended to be integrated into the AASHTO LRFD Bridge Design Specifications.
