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.
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.
A relatively inexpensive monitoring system could be installed in the San Francisco-Oakland Bay Bridge to easily detect signs of corrosion in the eastern span’s foundation and warn engineers. That’s what School of Civil and Environmental Engineering Professor Emeritus Lawrence Kahn told the San Francisco Chronicle November 21.
