Title Seismic Performance and Post-Earthquake Resilience of Highway Systems

Speaker: Stu Werner Seismic Systems & Engineering Consultants, Oakland CA Abstract: Protection of life safety is no longer the sole requirement for the successful seismic design of bridges and other highway structures. Design to maintain acceptable highway-system performance and resilience that reduces post-earthquake traffic disruptions and ensures rapid restoration of traffic flows is also vital for facilitating emergency response, reducing economic losses, and reducing socio-economic impacts of earthquake damage. This presentation will address this issue, which is now being investigated under a new research project that is part of a continuation of the multi-year FHWA Seismic Research Program. The presentation will also describe the REDARS methodology and software for seismic risk analysis of highway systems, its application to the assessment of highway-system performance and resilience, and future directions for its continued development.Duration About 40-45 minutes for presentation, plus time for questions and discussionBio. Stu Werner has over 40 years of experience in earthquake engineering and risk analysis of highway, seaport, and air transportation systems and structures. His work in this area has included design peer review, analysis, full scale testing, and system risk analysis for diverse clients that have included the Federal Highway Administration, Caltrans, Port of Los Angeles, Port of Oakland, BART, San Francisco Airport, US Geological Survey, FEMA, CH2M Hill, URS, and Oregon DOT. Since the mid-1990s, Stu has led the development of REDARS and its application to highway systems in earthquake-prone regions nationwide. He is president of Seismic Systems & Engineering Consultants in Oakland CA, has published over 130 papers that describe his various earthquake engineering activities, and is a recent recipient of the ASCE C. Martin Duke award in recognition of his contributions to the advancement of lifeline earthquake engineering.
