Title: Dam Safety Research Using NEES Equipment Sites A GrandChallenge Proposal submitted and Denied by the
1Dam Safety Research Using NEES Equipment Sites
A Grand-Challenge Proposal submitted (and
Denied by) the National Science Foundation
21. What is NEES
- NEES (Network of Earthquake Engineering
Simulations, http//nees.org ) opens the field of
earthquake engineering research to a broader and
more diverse community by - Provides access to the world's largest and most
advanced experimental facilities for performing
earthquake engineering experiments - Operates an IT infrastructure capable of
integrating lab experiments with computer models - Motivates the research community to collaborate
with distant colleagues using a shared, web-based
environment - Fosters the open exchange of data and information
among researchers and practicing engineers
through shared, web-accessible repositories - Creating active programs of education and
outreach committed to improving seismic safety
3NEES SITES
- Each of NEES's 15 shared laboratory facilities
enables researchers to explore a different aspect
of the complex way that soils and structures
behave as a result of earthquakes and tsunamis. - The laboratories fall into five general
categories - Shake tables
- Tsunamic wave basin
- Geotechnical centrifuge
- Field experimentation and monitoring
- Large-scale laboratory experimentation (e.g. CU-
Boulder) - NSF committed to 5 5 years of funding, we are
embarking in year 3! - http//nees.org

80 million infrastructure30 million/year for
10 years, total 400 millions
6Grand-Challenge Proposals
- Every year NSF/NEES fund one new Grand-Challenge
Proposal which responds to major societal needs. - University of Colorado and 10 other Universities
submitted a proposal to investigate the seismic
safety of dams and levees.
7Preliminary list of research needs collected by
Bureau
8VISION of Research Proposal
- Advance the State of the Art and the State of the
Practice in seismic safety assessment of dams and
levees through the integration of collaborative
research and engineering education using the
unique experimental and IT resources of NEES.

11TASKS
- Numerical simulation Modify OpenSees to enable
the seismic risk assessment of - Concrete arch and gravity dams
- Embankment dams and levees (with risk of
liquefaction) - Evaluation of Concrete Dams
- Field tests of concrete dams forced vibration
tests (using UCLA equipment). - Shaking table test of a concrete dam with
mitigation scheme (at U-Nevada, Reno shaker) - Laboratory tests of dynamic uplift in concrete
dams (at U-Colorado FHT equipment site). - Engineering validation Validation and
verification of OpenSees software for Concrete
dams. - Probabilistic safety assessment and fragility
curves Determination of fragility curves for
concrete dams with and without mitigation
measures. - Evaluation of Embankment Dams and Levees
- In Situ characterization of levees and embankment
dams field tests to characterize dam/levee
materials (using U-Texas-Austin equipment) - Centrifuge tests of improved and non-improved
embankment dams, levees (at UC-Davis equipment
site) - Engineering validation Validation and
verification of OpenSees software for
geotechnical structures. - Probabilistic safety assessment and fragility
curves Determination of fragility curves for
embankment dams and levees with and without
remediation measures. - Socio-Economic Impact
- Flood simulation Dynamic simulation of flood
resulting from the breaching of a dam. - Societal impact of dam failure on evacuation,
disaster planning and critical infrastructural
systems, warning system assessment. - Outreach and International
- Education Outreach (EO) to K-12
Undergrad./graduate students Profession Public.

17Data Archiving
- The Data Sharing and Archiving Policies and
Guidelines of NEESinc (2006) will be strictly
abided. - Not only will relevant data from laboratory and
field tests be uploaded in a timely fashion, but
also all validation and verification problems
will be stored in the NEES repository. - Should NEESinc authorize it, we will also ask our
international collaborators to contribute to this
archive.
18International Collaboration

Dams - Canada Prof. Leger, Polytechnique de Montréal
- China Prof. Houqun Chen (Member of the Chinese
Academy of Science), and Prof. Haibo Wang of the
China Institute of Water Resources and Hydropower
Research - India Prof. Paul, IIT of Roorke
- Italy CESI-RICERCA and Politecnico of Milano
- Iran Prof. Ghaemian, Shariff University
- Japan The Tokyo Electric Power Company (TEPCO)
- Switzerland Prof. Springman, ETH/Zurich and
Stucky Engineers - Turkey Prof. Tosun President of the Dam Safety
Association in Turkey and Prof. Mustafa Erdik
Chair of the Dept. of Earthquake Engineering at
Kandilli Observatory.
19Budget, Duration
- 5 years
- 3.7 Million
- A lot of bureaucracy
- Easy access to NEES laboratories
20Outcome
- Proposal denied
- Can resubmit (modified) proposal in January 2008.
- Must bring dams to the attention of NSF
- Try to seek matching funds from xx to boost the
chances of success in 2008 (about 300k/year for
4 years from industry/governmental agencies)
