NEES@UNR

The NEES Equipment Site at the University of Nevada, Reno is a biaxial, multiple-shake-table facility (with three identical biaxial shake-tables) that is suitable for conducting research on long, spatially distributed, structural and geotechnical systems. The facility is also capable of testing conventional structural and non-structural systems by using the tables in large-table-mode, and operating them as a single unit.

Major performance characteristics of one shake table are summarized in the following table. Further details of the shake tables and other NEES as well as non-NEES equipment provided by the Facility along with technical documentation, AutoCAD drawings, tools, etc. can be accessed by following the links above; namely, General, Equipment, Data Acqusition, Instrumentation, and Other.
