A new design from BIG made using 3D printing and mycelium additives is being showcase at a manufacturing summit for industry stakeholders in Scandinavia. The firm says it is "aimed at exploring new ways to reduce spatial and material waste through additive manufacturing and bio-based... View full entry
A group of researchers from the Polytechnic University of Valencia say they have discovered a means for protecting buildings from structural collapse. In a new set of building science experiments conducted in June 2023, they carefully studied animal neurobiology. El País tells us: “The team of... View full entry
Today is World Engineering Day, and to celebrate it, Archinect has curated a few outstanding bridge projects we’ve included in our recent news coverage to highlight critical pieces of infrastructure at an important time for civil and structural engineering in the Americas and abroad.

San Francisco’s ill-fated Millennium Tower is making headlines once again for problems taking place beneath its turbulent foundation. This time, the 58-story skyscraper is sinking even further on its vertical axis as it settles to the north and west, alarming some building scientists who... View full entry
Researchers based at the Drexel University College of Engineering have devised a new method for performing structural safety inspections using autonomous robots aided by machine learning technology. The article they published recently in the Elsevier journal Automation in Construction presented... View full entry
More than one hundred schools and education settings in the United Kingdom have been closed due to concerns over the integrity of concrete roof panels. So far, 147 schools are known to contain reinforced autoclaved aerated concrete (Raac), with approximately one hundred fully or partially closed... View full entry
Despite initial progress in the first phase of the so-called fix earlier this year, the sinking and leaning Millennium Tower in San Francisco is now tilting more to the west than ever, according to monitoring data reviewed by NBC Bay Area’s Investigative Unit.
The tower is currently leaning more than 29 inches at the northwest corner of Fremont and Mission streets, much of the added tilt occurring during the digging needed to prepare to support the tower along two sides.

The data came from a rooftop monitoring system, which the fix’s chief engineer Ron Hamburger said was less reliable than the one contained in its foundation before stating the half-inch tilt recorded was "negligible." A geotechnical engineer working on the $100 million project expressed his... View full entry
Earlier this month, the Verrazano-Narrows Bridge was closed due to weather. However, a video posted to Twitter of the bridge undergoing heavy winds went viral due to the sights and sounds recorded. Bridges are built to pass strict safety and construction standards and be capable of withstanding... View full entry
In a new paper published in Nature Materials, the researchers showed that the diagonally-reinforced square lattice-like skeletal structure of Euplectella aspergillum, a deep-water marine sponge, has a higher strength-to-weight ratio than the traditional lattice designs that have used for centuries in the construction of buildings and bridges. — Harvard School of Engineering and Applied Sciences (SEAS)
Matheus Fernandes, a graduate student at the Harvard John A. Paulson School of Engineering and Applied Sciences said in a statement: "We found that the sponge's diagonal reinforcement strategy achieves the highest buckling resistance for a given amount of material, which means that we can build...

Next year, if all goes well, a pair of footbridges intended to be cancer-proof will open in Geelong, a town 75km south-west of Melbourne, Australia. These bridges, which will act as prototypes for more than 150 others planned for the expanding city, will be constructed using a novel approach that combines glass-fibre and carbon-fibre rebars. They will, though, cost about the same as equivalent conventional bridges. — The Economist
The potentially ground-breaking construction approach has been developed by Australian university Deakin and Austeng, an engineering firm. The structural system selectively deploys pricey carbon fiber rebar to strengthen the construction assembly where necessary, while glass fiber rebar members... View full entry
The cracks discovered beneath the rooftop park were classic brittle fractures. The tapered 4-inch-thick steel beams—2.5 feet wide and 60 feet long, with a horizontal flange on the bottom—undergirded the 5.4-acre park on the building’s fourth level, and buttressed the roof of the bus deck on the second level. By themselves, the cracks formed a point of weakness with potentially hazardous consequences. But they also suggested the possibility of a larger crisis. — Popular Mechanics
Popular Mechanics offer a detailed recap of the events following the discovery of two cracked structural steel beams in the brand new $2.2 billion, Pelli Clarke Pelli-designed Transbay Transit Center in San Francisco in 2018. View full entry
The National Transportation Safety Board members that have been investigating a March 15, 2018 bridge collapse at Florida International University have concluded that the design firm FIGG Bridge Engineers, Inc. responsible for the project underestimated the loads created by the bridge's concrete...

The priority remained on stabilizing the building, two days after the top floors collapsed on one another, sending debris to the street below and killing two people. One worker remained missing, and authorities have said they also want to find him before moving onto an investigation into what happened. — 4WWL
According to 4WWL the cause of the collapse isn't clear. Jean Mattei, former president of the American Society of Civil Engineers, said that it is currently too difficult to know what caused the failure, reports 4WWL. "From the videos and from what I've seen, it was something that started at the... View full entry
Researchers at MIT have proven Leonardo da Vinci correct yet again, this time involving his design for what would have been at the time a revolutionary bridge design. Although clients rejected da Vinci's work at the time, over 500 years later, the researchers have proven that his bridge would have worked. — Popular Mechanics
Part of a proposal for Sultan Bayezid II of the Ottoman Empire, da Vinci's bridge was intended to connect what is now Istanbul to Galata, a neighboring city. The proposed design spanned about 918 feet and was of masonry construction, making use of the compressive characteristics of an arc... View full entry
