A leading standards-setting transportation organization has named a project by Georgia Tech and Georgia Department of Transportation researchers one of the year’s most valuable. The work developed a new steel to reinforce concrete bridge piles in marine environments that withstands corrosion and lasts well beyond the expected 100-year lifespan of the structures.
The National Science Foundation has funded a new collaboration between three School of Civil and Environmental Engineering researchers that could make finding damage in bridges or buildings easier and help reduce life-threatening failures. If successful, the team will be able to produce more reliable predictions about how structures behave, and their algorithm will be able to do the predictions much more quickly than current practice for structural damage and deterioration assessments.
Chloe Johansen, a School of Civil and Environmental Engineering Ph.D. student, is working on an idea with Assistant Professor Iris Tien they think will make a difference in improving America's crumbling infrastructure. It's work with so much potential that Johansen is working with other Georgia Tech and Emory University graduate students to commercialize her research.
With Hurricane Matthew looming, college football programs throughout the Southeast had to consider the impact of the massive storm on their scheduled games Oct. 8. Two games has to be postponed — one indefinitely — prompting the Atlanta Journal-Constitution’s SEC Country website to ask what would happen to a stadium in a major hurricane.
Walking toward Lauren Stewart’s office, you immediately smell the odor of glue in the air. A quick glance around reveals model bridges in various states of completion lying about a student work area as harried undergraduates work to finish class assignments. Stewart, an assistant professor in civil and environmental engineering, teaches a beginning structures course, so this is a recurrent theme each semester. Stewart herself, however, is more at home with the smell of explosives and destruction rather than construction.
Lauren Stewart will spend some of her summer at Eglin Air Force Base in Ft. Walton Beach, Florida, working to better understand how military components react when they strike a “hardened target.” Stewart has received a summer faculty fellowship from the Air Force Research Lab.
A paper detailing a type of origami tube that is strong and reconfigurable will be recognized in May as one of the best studies published in the Proceedings of the National Academy of Sciences in 2015. The editors of the journal have selected the research for the Cozzarelli Prize, an annual award for scientific excellence and originality.
A chunk of concrete dropped off a wall into traffic Jan. 30 in the Yerba Buena Island tunnel that’s part of the San Francisco-Oakland Bay Bridge. Now the California Department of Transportation is investigating whether there’s more corrosion in the tunnel that could lead to other problems.
Origami, the ancient art of paper folding, may soon provide a foundation for antennas that can reconfigure themselves to operate at different frequencies, microfluidic devices whose properties can change in operation – and even heating and air-conditioning ductwork that adjusts to demand. The applications could result from reconfigurable and reprogrammable origami tubes developed by researchers at three institutions, including the Georgia Institute of Technology. By changing the ways in which the paper is folded, the same tube can have six or more different cross sections.
