Researchers simulate quake to improve bridge design

09/26/2011 | United Press International

A 145-foot-long steel bridge model sits atop four shake tables at the University of Nevada, Reno's Large-Scale Structures Earthquake Engineering Laboratory. Six full-size pickup trucks cross it as researchers simulate an earthquake, looking to enhance the seismic design of future bridges. "With increasing truck traffic and frequent congestion on city freeways, the likelihood of an earthquake occurring while a bridge is fully laden is now a possibility that should be considered in design," says Ian Buckle, a civil engineering professor and the lab's director.
