Is funding secured for OKC skyscraper project? Is it actually viable? What we know

However, Dellate, along with Jerome Hajjar, a professor at Northeastern College of Engineering in Boston, both said despite concerns about Oklahoma’s location within Tornado Alley, among others, the tower is doable from a structural standpoint.

Time is running out to find survivors.

Many of the buildings in the earthquake zone appear to be lightly reinforced concrete and masonry structures that are several decades old, said Jerome F. Hajjar, a structural engineer at Northeastern University who specializes in earthquakes.

IN THE BIG DIG’S SHADOW

Thanks largely to computer modeling, engineers now have a better idea how a building can — or can’t — be built, said Jerome Hajjar, an engineering professor at Northeastern University. 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 […]

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 […]

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.

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, […]

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. Taxpayers could be on the hook for the […]

How did a container ship collision cause a Baltimore bridge to collapse? Structural engineer details possible design factors

Northeastern professor Jerome Hajjar says the ship collision may have exceeded “the expected loads at the time of the bridge design.”

Rendering of what the tallest building in Oklahoma would look like.

The tallest building in the US is planned for the middle of Tornado Alley. Will the high-rise withstand the region’s extreme weather?

Jerome F. Hajjar, professor of civil and environmental engineering, says paramount to good design is building with sustainability.

Jerome Hajjar honored with lifetime achievement award from Structural Stability Research Council

Jerome Hajjar has been tapped to receive the 2024 SSRC Lynn S. Beedle Award from the Structural Stability Research Council and is set to become president of the Structural Engineering Institute.

Indonesia is building a new capital. Will it be a model amid climate change?

Jakarta, a congested city of 30 million people, is sinking. Northeastern experts examine Indonesia’s plans to create a new, green capital 800 miles away.

After two major earthquakes rocked the state, is California ready for ‘the Big One’?

Two powerful earthquakes shook Southern California in back-to-back days last week, stoking fear among residents that a major earthquake isn’t far off. Jerome F. Hajjar, a professor of civil and environmental engineering at Northeastern, says it’s not a matter of if California will experience a huge, devastating earthquake, but when. And only some of the buildings in the state are prepared to withstand such a quake, he says.

Northeastern University faculty members reflect on their commencement ceremonies

Passing around a quart of iced tea to stay hydrated. Corralling a loose cat. Getting drenched by torrential rain. We asked five faculty members from across the university’s schools and colleges to reflect upon their commencement ceremonies.

‘There is enough wind energy capacity off the east coast to power the entire country’

While countries in Northern Europe have been using wind energy for more than two decades, the United States hasn’t invested much in the technology. But that’s all starting to change. “This is an industry that is about to explode,” said Jerome Hajjar, an expert on infrastructure design and professor of engineering at Northeastern.

Building for collapse: Professor designs more resilient steel structures

Buildings all over the world have succumbed to earthquakes because they were designed never to collapse at all. As a result, these structures are not resilient to unforeseen events, said professor Jerome Hajjar, who delivered the 54th annual Robert D. Klein Lecture on Monday.

Engineering prof says Florida bridge collapse an anomaly, urges close look at old structures

Jerome Hajjar, CDM Smith Professor and chair of the Department of Civil and Environmental Engineering, says the use of accelerated bridge construction has increased in the past decade, and other instances have been proven safe.

Challenges, opportunities ahead for repairing nation’s aging infrastructure

President Donald J. Trump has identified repairing the nation’s aging infrastructure as a national priority. Jerome Hajjar, professor and chair of the Department of Civil and Environmental Engineering, says “infrastructure requires consistent, significant investment,” and that engineers are primed to develop cost-effective solutions to address this national priority.
