报告内容：Performance-based design (PBD) concept, originally developed for buildings in 1990s, has made it way into the design and assessment of bridges in recent years. The developments have promoted the advancement in the nonlinear analysis models and procedures accounting for soil-structure interaction, inelastic structural elements, and foundations etc and the probabilistic seismic demand assessment of bridges with considerations of uncertainties and variability in earthquake hazard characterization, analysis methods and damage prediction. Comparing to performance-based design for buildings, there are several major differences in implementing the PBD concept for bridges including intensity measures, analysis considerations, quantification of damage at component level and system failure probability etc. The fragility functions can be developed and utilized to provide vital information of bridges' system behavior and damage mechanisms. This presentation will summarize our recent research in these areas and provide a framework for implementing the performance-based assessment of bridges.
