PurposeVision 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


ThemeParticipants unanimously identified

resilient and sustainable communities as 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 Barack ObamaNational Preparedness Month, A Proclamation By

The President of the United States of America, September 4, 2009


Principal DirectionsMetrics to quantify resilienceHazard prediction and risk communicationExisting structures and infrastructureNew materials, components and systemsMonitoring and assessment of resilienceSimulation of systemsTechnology transfer


Metrics to Quantify ResilienceDefinition 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 occupantsLifecycle considerationsMulti-hazard


Hazard Prediction & Risk CommunicationNew technologies will enable enhanced

situational awareness in real-timeAssess structural integrityCommunication for search and rescueComprehensive evaluation of an event

Fundamental requirements are smart, ubiquitous sensors, system level models for prediction, data collection and processing systems


Renewal and Existing StructuresExisting vulnerable physical assets

Uncertain inventory / conditionHigh costs of mitigation strategiesLimited existing decision support tools

Need experimental and computational tools to assess the hazard, manage the inventory, and evaluate the condition

New Materials, Elements and StructuresResilient structures enabled by

Auto-adaptive materialsNew, modular construction techniques Physics-based modeling of materials Quantification of advantages

Deployment requires re-design of the components and the systems, and experimental verification

Monitoring and AssessmentInstrumenting the built and natural

environmentsIntegrating real-time data

Event detectionPost-event response planningModel validationDiagnosis and prognosis Human response

Reduce, ingest and aggregate vast amounts of data


Simulation of SystemsCentral to improving resiliencyFuture 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 TransferMeasurable impact will be achieved

by transfer of this knowledge to practice of engineering, building codespublic policy, decision making and behaviorhazards other than earthquakespublic-at-large

Research to advance technology transfer – education, communication, social media, etc.


Role of NEESSimulation

PhysicalComputationalHybrid

CyberinfrastructureDataCollaborationEducation


Role of NEES

Improved data collection and information management capabilities

Cyberinfrastructure resources to support the data structures and visualization methods

State-of-art capabilities to support innovative testing, data preservation, and collaboration


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

Techniques for use of new materials and

elements

Real-time structural assessment and data assimilation methods

New types of large-scale

field testing equipment


Role of NEES

World-class facilities to enable training of the next generation of researchers and practitioners


ConclusionAchieving 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
