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 ID Coordination– Cost-Effective Engineering Solutions Research– Political Skill and Will Leadership– Good Construction/Maintenance Practices Partnership
