SEISMIC DESIGN PHILOSOPHIES AND PERFORMANCE-BASED DESIGN CRITERIA. IN: BRIDGE ENGINEERING: SEISMIC DESIGN

This paper discusses the bridge design philosophies and current practice in the United States. No-collapse based design is usually applied to ordinary bridges, and performance-based design is used for important bridges. Some sample performance-based seismic design criteria are presented as a reference guide. The paper has attempted to address only some of the many issues incumbent upon designers of bridges for adequate performance under seismic load.
