Purpose • Vision 2020 was established to formulate a vision of where earthquake engineering in the US needs to be in 2020 to vigorously address the grand challenge of mitigating earthquake and tsunami risk. • principal new directions in research, practice, education • reflect on the role of the NEES network
Theme • Participants unanimously identified resilient and sustainable communitiesas the overarching theme to guide future efforts • Involves • physical systems (e.g. buildings, highways, sanitation, subways, communications, energy facilities) • human systems (e.g. local population and its associations such as schools, banking and insurance systems; socioeconomic and legal frameworks that guide decisions)
“Our goal is to ensure a more resilient Nation - one in which individuals, communities, and our economy can adapt to changing conditions as well as withstand and rapidly recover from disruption due to emergencies.” -- President BarackObama National Preparedness Month, A Proclamation By The President of the United States of America, September 4, 2009
Principal Directions • Metrics to quantify resilience • Hazard prediction and risk communication • Existing structures and infrastructure • New materials, components and systems • Monitoring and assessment of resilience • Simulation of systems • Technology transfer
Metrics to Quantify Resilience • Definition for resilient communities within the context of the engineering profession • Need expectation of performance levels before, during and after earthquakes • Structures (new and existing) • Lifelines and occupants • Lifecycle considerations • Multi-hazard
Hazard Prediction & Risk Communication • New technologies will enable enhanced situational awareness in real-time • Assess structural integrity • Communication for search and rescue • Comprehensive evaluation of an event • Fundamental requirements are smart, ubiquitous sensors, system level models for prediction, data collection and processing systems
Renewal and Existing Structures • Existing vulnerable physical assets • Uncertain inventory / condition • High costs of mitigation strategies • Limited existing decision support tools • Need experimental and computational tools to assess the hazard, manage the inventory, and evaluate the condition Courtesy of Quakewrap
New Materials, Elements and Structures Courtesy of Hong-Nan Li Courtesy of BigFish • Resilient structures enabled by • Auto-adaptive materials • New, modular construction techniques • Physics-based modeling of materials • Quantification of advantages • Deployment requires re-design of the components and the systems, and experimental verification L Chico et al. Phys Rev Lett 76, 971 (1996)
Monitoring and Assessment • Instrumenting the built and natural environments • Integrating real-time data • Event detection • Post-event response planning • Model validation • Diagnosis and prognosis • Human response • Reduce, ingest and aggregate vast amounts of data
Simulation of Systems • Central to improving resiliency • Future work should consider • Multi-scale models and multi-physics models • Hybrid experiments involving both physical and social infrastructures • Consider not only components, but systems and interacting elements
Technology Transfer • Measurable impact will be achieved by transfer of this knowledge to • practice of engineering, building codes • public policy, decision making and behavior • hazards other than earthquakes • public-at-large • Research to advance technology transfer – education, communication, social media, etc.
Role of NEES • Simulation • Physical • Computational • Hybrid • Cyberinfrastructure • Data • Collaboration • Education
Role of NEES • State-of-art capabilities to support innovative testing, data preservation, and collaboration • Cyberinfrastructure resources to support the data structures and visualization methods Improved data collection and information management capabilities
Role of NEES Enhanced capabilities for simulation of complex systems Access to national high-performance computing resources Developments to integrate social, physical and numerical components
Role of NEES • New types of large-scale field testing equipment • Real-time structural assessment and data assimilation methods • Techniques for use of new materials and elements
Role of NEES • World-class facilities to enable training of the next generation of researchers and practitioners
Conclusion • Achieving the 2020 Vision will require a revolutionary change in the processes deployed to generate fundamental knowledge and develop enabling technologies • Earthquake engineering disciplines will need to work together to accelerate progress • The NEES Collaboratory will play a key role
