Investing in America’s infrastructure: Faculty weigh in on what to address in proposed infrastructure legislation

Cars and trucks drive on an interchange with roads branching off in several directions.

A bipartisan group of senators has announced a $1.2 trillion infrastructure framework, which aims to make transformational investments in infrastructure for transportation, clean water, universal broadband, renewable energy, remediation of legacy pollution, and resilience to the changing climate.

Georgia Tech Team Wins $1 Million Grant to Lead University Transportation Center

A team led by Georgia Tech researchers has been awarded a $1 million grant from the U.S. Department of Transportation to address declining transit ridership. The grant establishes the research consortium as one of four new Tier 1 University Transportation Centers (UTCs), which are funded to address critical transportation challenges facing the United States. Just four teams were selected from nearly 70 applications to receive the UTC grants.

Usually when researchers need to understand what happens when you blow something up, they have to go outside and actually, well, blow it up.

NSF workshop sets out to define ‘bio-inspired geotechnics’ and lay groundwork for new collaborations

Alejandro Martinez welcomes engineers, biologists, physicists and others to the First International Workshop on Bio-Inspired Geotechnics in May at the University of California, Davis. The unique gathering aimed to better define the emerging field of bio-inspired geotechnics and connect researchers from a broad range of disciplines to collaborate on groundbreaking ideas in the area.

A melting pot of experts with research interests as diverse as geotechnical engineering, termite burrowing, tree physiology, granular physics and soft robotics trickled in from around the world in late May for the First International Workshop on Bio-Inspired Geotechnics. The NSF-funded workshop brought together 60 experts from engineering and science research, as well as industry, to foster dialogue and collaborations to better establish the field of bio-inspired geotechnics.

Dashing the dream of ideal ‘invisibility’ cloaks for stress waves

Roman arenas have survived in many earthquake-prone regions. Did the Romans inadvertently build seismic wave cloaks when they designed colosseums? Some researchers believe they did due to the arenas' resemblance to modern experimental elastodynamic cloaking devices. (Photo: Paolo Costa Baldi via Wikimedia Commons)

Whether Harry Potter’s invisibility cloak, which perfectly steers light waves around objects to make them invisible, will ever become reality remains to be seen, but perfecting a more crucial cloak is impossible, a new study says. It would have perfectly steered stress waves in the ground, like those emanating from a blast, around objects like buildings to make them “untouchable.”

New tool will give large concrete structures what amounts to an ultrasound, finding tiny cracks before they grow

A researcher measures the width of a crack in a reinforced concrete column after testing the strength of the column. A new project funded by the U.S. Department of Energy Advanced Research Projects Agency will develop a field-deployable tool to detect cracks far smaller than this — and inside rather than outside — thick reinforced concrete structures. (Photo: Chris Kiser)

Imagine giving large concrete structures something similar to an ultrasound and getting images so detailed you can see cracks just a tenth of a millimeter long. That level of detail just isn’t possible now. Yet such capability could revolutionize how engineers assess the health of thick reinforced concrete infrastructure like dams and power plants and bridges.
