University of Nevada, Reno » Mimicking the large ground motions of the deadly and damaging 1994 Northridge, California earthquake but amplified to a magnitude 7.5., the 100-ton, 70 foot long bridge was sitting on three large shake tables in the University of Nevada, Reno Earthquake Engineering Laboratory. The demonstration was the first large-scale bridge model to test five principles and techniques of accelerated bridge construction combined in one bridge model.
