A substantial
improvement in capability of the research community to study the
earthquake response of civil engineering systems has been achieved
through the establishment of NEES. The primary objectives of this
project are two folds: (1) to demonstrate how researchers from
multiple universities can conduct collaborative research using
a network of experimental facilities distributed around the country
and utilizing the advanced NEES information technology tools to
collect, communicate, and archive large volumes of data, and (2)
to conduct high quality studies of soil-foundation-bridge structure
systems. Click

Due to the complexity of structural performance during strong earthquakes and the highly nonlinear response of structural systems, computer simulations have to be verified with experimental data to establish their reliability. Calibration of computer simulation tools requires data on models that realistically represent not only structural components, but also the interaction among them and system response. The scale has to be sufficiently large to replicate both the macroscopic and microscopic structural response. This is particularly important for Performance-Based Design (PBD) in which localized damage can be the performance criterion. While the research community has successfully studied different aspects of component behavior, it has not been able to experimentally evaluate the system behavior because of the lack of large-scale testing facilities, high capacity testing equipment, and the necessary information technology (IT) infrastructure.
