Description

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.

Keywords: abutment; bridge; column; connections; design; earthquake; footing; girder; hinge; restrainer; seismic; seismic analysis; seismic isolation.
