BUFFALO, N.Y. -- A magnitude 7.0 earthquake will strike at the University at Buffalo on May 18 as researchers conduct tests on a 70-ton, 60-foot-long concrete bridge in the university's massive Structural Engineering and Earthquake Simulation Laboratory (SEESL).
See a video clip of a preliminary test at http://seesl.buffalo.edu/projects/accelbridge/video.asp
WHEN AND WHERE: At 10 a.m. on Tuesday, May 18 on the first floor of Ketter Hall on UB's North Campus.
Researchers from UB and MCEER (formerly the Multidisciplinary Center for Earthquake Engineering Research) will provide a brief project overview. They will then conduct two powerful earthquake tests on the half-scale bridge, which has been erected across UB's twin shake tables.
The UB seismic test, funded by the Federal Highway Administration, will be the largest bridge specimen ever tested on a shake table and will incorporate a rapid and cost-effective construction method called Accelerated Bridge Construction (ABC).
Hundreds of bridges have been built around the U.S. using this speedy, new construction method, but questions remain about how such bridges might perform under earthquake conditions in California or other seismically active regions.
The concern is that these bridges are basically concrete boxes held together by steel tendons (cables) that potentially could snap during an earthquake.
For the past two weeks, the UB/MCEER researchers have been subjecting the bridge to increasingly powerful simulated earthquakes.
On May 18, it will undergo its most powerful seismic test.
UB's unique Structural Engineering and Earthquake Simulation Laboratory, with its twin, relocatable shake tables, is likely the only place in the nation that could perform this kind of test. It demonstrates the unique ability of UB and MCEER to develop and evaluate technological innovations that are increasingly critical in addressing the nation's aging infrastructure, especially advances that can save time and money.
Since 1992, UB and MCEER have attracted more than $30 million in Federal Highway Administration contracts.
Great visuals. Great infrastructure story.
