What is NEES?
The George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) is a national, networked, simulation resource that includes geographically-distributed, shared-use, next-generation experimental research Equipment Sites built and operated to advance earthquake engineering research and education through collaborative and integrated experimentation, theory, data archiving, and model-based simulation. The goal of NEES is to accelerate progress in earthquake engineering research and to improve the seismic design and performance of civil and mechanical infrastructure systems through the integration of people, ideas, and tools in a collaboratory environment. Open access to and use of NEES research facilities and data by all elements of the earthquake engineering community, including researchers, educators, students, practitioners, and information technology experts, is a key element of this goal.
What is nees@UTexas?nees@UTexas is an equipment site that specializes in dynamic field testing using large-scale shakers. The nees@UTexas equipment includes five mobile shakers that have diverse force and frequency capabilities, an instrumentation van that houses state-of-the-art data acquisition systems, and a large collection of field instrumentation. The field equipment can be used in a variety of applications, including shear wave velocity characterization, liquefaction testing, geophysical testing, and dynamic testing of structures. During experiments the instrumentation van can connect to the NEESgrid via wireless uplink, allowing offsite access to both live video and data. NEES@UTexas Overview Poster (PDF, 181KB)
