UB NOW: Earthquake Testing

A major earthquake struck a 70-ton concrete bridge at the University at Buffalos Structural Engineering and Earthquake Simulation Laboratory, but left the structure virtually undamaged. It was a test to help engineers evaluate if a fast, new construction method can build bridges strong enough to withstand seismic activity. The information gathered could usher in a new era in bridge construction in seismic areas like California.

Earthquake Test- Building Better Homes -- Improving Structural Engineering with Earthquake Simulator

Improving Structural Engineering with Earthquake Simulator January 1, 2007 — To develop designs that can survive extreme seismic events, and to devise retrofit solutions for older homes, civil engineers who specialize in structural design test realistic models of homes in earthquake simulators. They place the homes on two adjacent shake tables designed to move in three directions, creating realistic earthquake motions. Cameras and accelerometers measure the rate of movement. BUFFALO, NY -- Homes are made to withstand the test of time. But the ultimate test is one that can survive a large-scale earthquake. And simulating an earthquake in a lab helps improve homes in real quake zones. Most people don't ever want to experience an earthquake. "I experienced a very strong earthquake in 1997 in Athens," Ioannis Christovasilis, an Earthquake Structures Graduate Student at University at Buffalo in NY, tells DBIS. "I was a little bit frightened, yes." University at Buffalo Structural Engineer Andre Filiatrault says, "We had an aftershock, maybe a magnitude five ... That was pretty dicey. You felt the shaking work up." But today, Filiatrault is eager to watch an earthquake simulator shake this house to a magnitude 6.7 quake. The full-scale, fully furnished home is built like many in earthquake zones, but prone to damage. The test shows how much shaking a wood home can endure. Filiatrault says, "We shook this building past its so-called design level. We shook it to an extreme event ...

Dissecting an Earthquake

University of Arkansas Professor Brady Cox, traveled to Haiti shortly after the magnitude 7.0 earthquake on January 12, 2010. While in Haiti Cox and members of the Geoengineering Extreme Events Reconnaissance (GEER), conduced research of the earthquakes impact on the built environment of Haiti.

Stanford Civil Engineering Professor on Haiti Earthquake

Anne Kiremidjian, professor of civil and environmental engineering at Stanford, says that it could take Haiti 10 years to recover from the earthquake that devastated the island nation on Jan. 12, 2010. Kiremidjian compared the energy from the temblor to that of a nuclear blast.
