This report is intended for use by practicing engineers and
provides a summary of the state-of-the-art analysis, modeling,
and design of concrete bridges subjected to strong earthquakes.
It is intended to supplement and complement existing documents
from the American Association of State Highway and Transportation
Officials (AASHTO), California Department of Transportation
(Caltrans), and various building codes and guidelines. Procedures
and philosophies of codes and guidelines are summarized. Linear
and nonlinear seismic analysis methods are also discussed, and
important modeling considerations for different bridge elements,
including curved girders and skewed abutments, are highlighted.
The report also includes a summary of general seismic-resistant
design and construction considerations for concrete bridges, as
well as analysis and design considerations for bridges with seismic
isolation.
