Shake Test Assesses Seismic Risk of Older Concrete Buildings (Video)

June 19, 2015

Georgia Tech researchers are using a shake table and sensor-equipped building replica to study concrete vulnerability in an earthquake in an effort to improve how older, reinforced-concrete buildings respond, reports Live Science.

They are searching for ways to retrofit older concrete buildings and are looking at several solutions, including mortar, high-strength steel rods and carbon-fiber sheets.

"There are hundreds of thousands of buildings that have not been retrofitted that ... are very dangerous," structural engineer Reginald DesRoches told Live Science.
