Big Bridge Gets Big Shakes in University of Nevada, Reno Earthquake Engineering Lab

Caption

A new, rocking, pre-tensioned concrete bridge support system has been developed by the University of Washington that reduces on-site construction time and minimizes earthquake damage. The 52-ton, 70-foot-long concrete bridge, built atop three 14- by 14-foot, 50-ton-capacity hydraulically driven shake tables at the University of Nevada, Reno, was shaken in a series of simulated earthquakes, culminating in the large ground motions recorded in the deadly and damaging 1995 magnitude 6.9 earthquake in Kobe, Japan.
