Media Advisory 07-003
And the Bridge Came Tumbling Down

8.0 magnitude indoor quake to test massive bridge

Shake tables were installed at the university in 2004.

Researchers studying the effects of earthquakes will use an array of three enormous shake tables to rend a 110-foot-long test bridge. Part of the National Science Foundation (NSF) George E. Brown Jr. Network for Earthquake Engineering Simulation (NEES), the University of Nevada, Reno, facility will be the first in the world to test a four-span bridge of this scale. The ultimate forces will reach twice the strength of the 1994 Northridge earthquake.

Who: Project Director M. Saiid Saiidi, University of Nevada, Reno, and visitors from NEES affiliates across the country
What: Test of bridge span under extreme earthquake forces. The heavily instrumented structure will be recording data to help engineers understand the impact of earthquake forces on bridges and other construction.
Where: The University of Nevada, Reno, campus in the James E. Rogers and Louis Wiener Jr. Large-Scale Structures Laboratory.
When: Thursday, Feb. 15 at 10 a.m. local time

The bridge model can be viewed anytime at: http://tpm.ce.unr.edu/perl/portal.pl?section=local_video.

The actual tests on Feb. 15 may be seen at: http://nees.ce.unr.edu/telepresence/

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
