Outline
The earthquake engineering community The George E. Brown, Jr. Network for
Earthquake Engineering Simulation NEESgrid – the collaboratory element of
NEES Challenges & Successes The field of dreams
SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN
The earthquake engineering community
Research– University-based– Funded by NSF and industry– Focus on simulation
Practice– Professional firms– Structural engineering (e.g., earthquake remediation)– Formulation of uniform building codes– Lifelines (e.g., ensure survival of roads, gaslines,
power distribution)

Survey methods
Technical surveys– Response from fourteen of fifteen sites
Practice survey (2002)– Administered to 444 engineers– 187 responses (42%)
• 11% non-NEES equipment sites• 9% women• 56% students• 39% from Year 1 (26% repeat response rate)

Earthquake engineers – in Hofstede’s scheme Power distance
– Hierarchical– Bias toward seniority
Individualist– “My lab is my empire”– Solo PI model
Masculine– Adversarial– Competitive
Uncertainty avoidance– Highly skeptical of new technologies– Extremely risk adverse
SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN
Grid specialists – in Hofstede’s scheme Power distance
– Egalitarian at development level– Bias toward talent
Collectivist– Use the Internet to create worldwide communities– Project model
Masculine– Adversarial– Competitive
Uncertainty avoidance– Extremely open to new technologies– Extremely risk seeking

Agreeing on termsTerm What grid specialists
heard What earthquake engineers heard
“user” HPC users
earthquake engineers
“community” NEES awardees broad array of earthquake engineers, including researchers and practitioners, in the diverse settings where earthquake engineering occurs (centers, under-represented institutions, under-resourced institutions)
“requirements” Description of high level system architecture
Description of detailed user requirements and their relationship to functional specifications

Successes Scientific
– First teleobservation of shake table (November 2002)
– First data saved to repository (November 2002) Community
– NEES Consortium incorporated (January 2003)– First NEES Consortium meeting (May 2003)– Use of prototype tools
Future– MOST experiment, July 2003– Operational collaboratory October 1, 2004

The field of dreams
I was sitting on the verandah of my farm house in eastern Iowa when a voice clearly said to me, “If you build it, he will come.” – Ray Kinsella in Shoeless Joe, by W.P. Kinsella
