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
