What Is NEES?

To fully understand the performance of structures under any loading, it is generally necessary to conduct integrated large-scale testing in combination with high-power computing using reliable models. The opportunity to study large-scale models of civil engineering systems was substantially expanded in 2004 by the establishment of the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) funded by the National Science Foundation Major Research Equipment Program.

The goal of NEES is to provide a national, networked collaboratory of geographically-distributed, shared-use, next-generation experimental research equipment sites, with teleobservation and teleoperation capabilities, which will transform the environment for earthquake engineering research and education through collaborative and integrated experimentation, computation, theory, databases, and model-based simulation to improve the seismic design and performance of U.S. civil and mechanical infrastructure systems.

The construction period was completed on September 30, 2004, the NEES collaboratory has entered its operational period from October 1, 2004 through September 30, 2014 and will be managed by the NEES Consortium.

NEES Equipment Sites

The NEES program provides unprecedented infrastructure for research and education, consisting of networked and geographically distributed resources for experimentation, computation, model-based simulation, data management and communication. Rather than placing all of these resources at a single location, NSF has leveraged its investment and facilitated research and education integration by distributing the shared-use equipment among 15 universities throughout the United States.

To ensure that the nation's researchers can effectively use this equipment, equipment sites are operated as shared-use facilities, and NEES is implemented as a network-enabled collaboratory. As such, members of the earthquake engineering community are able to interact with one another, access unique, next-generation instruments and equipment, share data and computational resources, and retrieve information from digital libraries without regard to geographical location.
