Example Research: ‘06 GC on Ports Wharf response Container crane response Liquefiable fill soils and Multi-disciplinary problem of national and international importance Multi-site, multi-partner team (engineering, logistics, social sciences) Buy-in and involvement from community from proposal stage Systems approach that emphasizes implementation Risk Framework: Probability of Berth Downtime Socio-Economic Impact & Decision Support
NEESinc Mission 1: Innovation Providing access to the world's largest and most advanced experimental facilities Operating an IT infrastructure capable of integrating lab experiments with computer models Motivating the research community to collaborate using a shared, web-based environment Fostering the open exchange of data and information among researchers and practicing engineers Creating active programs of education and outreach committed to improving seismic safety Revolutionize earthquake engineering research and education by:
NEESinc Mission 2: Earthquake Risk Mitigation Engineering/Construction of Resilient Infrastructure is Best Strategy: –Complements land use, earthquake preparedness, and emergency response –Great strides have been made but Cost-Effectiveness is still an issue –From prescriptive codes to performance-based design Success Requires: –Effective Design Tools for Hazard IDCoordination –Cost-Effective Engineering Solutions Research –Political Skill and WillLeadership –Good Construction/Maintenance PracticesPartnership
