Designers can test different layouts or materials in ways they couldn’t in years past. “It doesn’t make it easy,” he said, “but it makes it […] Article What does poor rating for collapsed bridge mean for others? Sometimes the deterioration is minor enough that the bridge will be put in the queue for repair and the frequency of inspections will increase, said Jerome Hajjar, professor and department chair at Northeastern University’s College of Engineering. “When a bridge is added to the queue, it can be years before there’s funding to take care […] Article Business Insider Civil engineers are adjusting designs and materials to make them more sustainable, but experts say many more solutions are needed At Northeastern University, professor Jerome F. Hajjar chairs the department of civil and environmental engineering. He said a useful way to think about how the shift to more sustainable engineering could be accelerated was by looking at the transition to buildings designed to better withstand or control damage from earthquakes. Article Pittsburgh Business Journal CMU robotics researchers develop flying robots to make images, find weaknesses in large structures Researchers at Carnegie Mellon University’s Robotics Institute are developing small, self-guided flying robots that use 3-D imaging technology to help engineers pinpoint and assess structural damage and other weaknesses in large structures, such as bridges and dams. A prototype version of the Aerial Robotic Infrastructure Analyst, or ARIA, has already successfully mapped a small bridge, […] Article Boston Herald Fixing `structurally deficient’ MBTA bridges carries $800M tab “In extreme cases, they close a bridge,” said Jerome F. Hajjar, chairman of the Civil and Environmental Engineering Department at Northeastern University. “If you’re not able to adequately maintain it, it’s very likely it will continue to deteriorate.” So far, no T rail bridges have been closed.
