Welcome to nees@UCLA

What is nees@UCLA?

The US National Science Foundation (NSF) has established the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) as a national, networked collaboratory of geographically-distributed, shared-use experimental research equipment sites. nees@UCLA is an equipment site specializing in field testing and monitoring of structural performance.

As a part of this program, the UCLA NEES program has developed a state-of-the-art mobile field laboratory to enable detailed, seismic performance characterization of full-scale structural and foundation systems. Through use of this equipment, it is possible to develop an inventory of field test results that provide significant new insights into the nonlinear response of full-scale structural systems, as well as soil structure interaction effects.

Watts Towers ProjectWatts Towers Project

NEES@UCLA is involved in a year-long study to discover the source of deterioration of the iconic Los Angeles Watts Towers. The data will assist a team of LACMA conservators in creating a long-term preservation plan for the monument.

In January 2013 Dr. Bob Nigor, co-PI of NEES@UCLA, and Dr. Alberto Salamanca, Development Engineer for NEES@UCLA, gave a tour of the Structures Lab to a group comprised of engineers from the Abu Dhabi Municipality, two USGS technicians, and two Kinemetrics (KMI) employees.

Levee 2012Levee 2012

In August 2012, NEES@UCLA returned to the Sacramento Delta to simulate an earthquake to test the security of the fragile system of levees in the Sacramento San Joaquin Delta.

New Zealand 2011New Zealand

Bob Nigbor, co-PI of NEES@UCLA, traveled to Christchurch, New Zealand in June 2012 to install high-resolution monitoring systems in 2 buildings to record both ambient vibrations and aftershock response. Phase II of the project followed in September 2011, when NEES@UCLA installed a high-resolution monitoring on the Christchurch Women's Hospital and an adjacent building to do remote monitoring for at least 4 months. In the first three months we have recorded more than 300 aftershocks!


nees@UCLA provided staff and instrumentation for large-scale destructive testing of a reinforced concrete structure on the E-Defense shake table in Japan.
