Comments Off on The world’s first 3D-printed steel bridge looks like it came from another planet

Dutch technology company MX3D  just officially unveiled the world’s first  3D-printed stainless steel bridge . It took four robots , nearly 10,000 pounds of stainless steel , about 684 miles of wire, and six months of printing to build the sinuous, undulating structure, which looks like it’s straight out of a science-fiction movie. The MX3D Bridge, designed by Joris Laarman Lab , is around 41 feet by 20 feet, and it’s made from a new kind of steel. 3D-printing created a ribbed surface as robots added layers upon layers; Gizmodo said it could be buffed out, but MX3D plans to keep the unique, rough look. Related: World’s first 3D-printed bridge opens in the Netherlands Laarman told Gizmodo it’s strange to glimpse the bridge in their workshop: “It’s a little bit like being in a science fiction story because it looks so different than everything else around. We work in a highly industrial shipyard where everything is geometric in shape, but this bridge doesn’t have a single straight line.” MX3D’s goal for the bridge project is “to showcase the potential applications of our multi-axis 3D-printing technology,” according to their website. They say they serve architecture , maritime and offshore, and heavy duty industry markets. There’s that spark of sci-fi on their About page too: their ultimate vision is robots creating lightweight constructions — not just bridges, or buildings, but Mars colonies as well. The company credits Arup for structural engineering, Heijmans as their construction expert, and AcelorMittal for metallurgical expertise, to name a few; several other companies and universities have been involved in the bridge project. MX3D’s bridge is to be installed over the Oudezijds Achterburgwal canal in Amsterdam , possibly in 2019. Before that, the bridge will undergo load tests. Co-founder Gijs van der Velden told Gizmodo they recently tested it with 30 people, and it behaved as it should. He told Gizmodo, “[Amsterdam city officials] have collaborated with us, Arup, and Imperial College London to define a method for evaluating the safety of the bridge as, of course for a novel production like this, there is no standard code. Their open attitude towards such a new and unconventional project was essential to make this project a success.” + MX3D + MX3D Bridge + Joris Laarman Lab Via Gizmodo Images courtesy of MX3D, Joris Laarman Lab, Adriaan de Groot, Thijs Wolzak, and Olivier de Gruijter

Boris Johnson proposes 22-mile bridge to connect UK and France

Comments Off on Boris Johnson proposes 22-mile bridge to connect UK and France

Could a 22-mile bridge crossing the English Channel help boost transport between the United Kingdom and France after Brexit ? Foreign Secretary Boris Johnson thinks so – he proposed the infrastructure project and spoke about a second link with France’s president Emmanuel Macron . Johnson reportedly said to Macron that it’s ridiculous that two of the largest economies in the world are joined by only one railway line. The publication said Macron “is understood to have responded positively.” Johnson tweeted a picture of the two of them flashing a thumbs-up after what he described as great meetings. En marche ! Great meetings with French counterparts today pic.twitter.com/D73B1rSkd3 — Boris Johnson (@BorisJohnson) January 18, 2018 Related: New bridge linking Japan and Russia could enable 8400-mile rail trip from London to Tokyo But some people put the brakes on the idea . The United Kingdom Chamber of Shipping, which represents over 180 maritime industry bodies, tweeted there would be challenges with such an undertaking. CEO Guy Platten told The Guardian the Dover Strait – at the English Channel’s narrowest part – “is the world’s busiest shipping lane” and that the largest ships going through the strait can be around 70 meters, or nearly 230 feet, tall. Others pointed out that such a bridge would be incredibly expensive. Building a huge concrete structure in the middle of the world’s busiest shipping lane might come with some challenges. https://t.co/jYD5O8B19W — UK Shipping (@ukshipping) January 18, 2018 Reuters reported France’s finance minister Bruno Le Maire told Europe 1 radio, “All ideas merit consideration, even the most far-fetched ones … Let’s finish things that are already under way before thinking of new ones.” And a spokesperson for prime minister Theresa May said there were “no specific plans” regarding a Channel bridge: “What was agreed yesterday, and I think that’s what the foreign secretary tweeted about as well, is a panel of experts who will look at major projects together including infrastructure.” But according to The Guardian, some engineers said the Channel bridge idea might not be so far-fetched; architect Alan Dunlop pointed to the Hong Kong-Zhuhai-Macau Bridge, which is around 34 miles long. Bridge designer Ian Firth told BBC Radio 4’s Today program the project would be entirely feasible, and that before construction of the Channel tunnel there were bridge options being considered. Firth said, “There are bridges of a similar, if not quite the same, scale elsewhere…It would be a huge undertaking, but it would be absolutely possible, and shipping impact issues could be dealt with.” Via The Guardian (1, 2) and Reuters Images via Wikimedia Commons ( 1 , 2 )

New indestructible bridge design was directly inspired by nature

Comments Off on New indestructible bridge design was directly inspired by nature

The job of structural engineers around the world is arguably getting more difficult. Many urban centers are experiencing booming populations and increased vehicle traffic, and environmental changes create new challenges for buildings, bridges, and roadways. New breakthroughs in engineering design from the University of Warwick could lead to indestructible bridges that rely on compression for their strength, and lack the weak points that make traditional bridges so vulnerable. And the design process is inspired by nature. Wanda Lewis of University of Warwick’s School of Engineering employs the process of ‘form-finding’ to create bridge designs that need little or no maintenance or repairs. For a quarter century, Lewis has been studying forms in nature to learn how simple stress patterns make it possible for delicate objects, such as a leaf on a tree, to withstand the intense force of wind, rain, or impact against a tree branch. Although she says “nature’s design principles cannot be matched by conventional engineering design,” she has developed a mathematical model that could lead to super durable manmade bridges . Related: Washington just built the world’s longest floating bridge The optimal arch—a fully self-supporting bridge structure—has been the target of engineers for centuries, and Lewis’ research could be the key that unlocks the next wave of structural engineering . Her mathematical models respond to the failings of the inverted parabola and the catenary form, classical theory’s only two existing concepts for an optimal arch which both have weak points. The new models could help engineers build bridges that can withstand not only heavy regular traffic, but also earthquakes, floods, and high winds. Her findings were recently published in the journal Proceedings of the Royal Society A: Mathematical, Physical and Engineering Science . Via Phys.org Images via University of Warwick and Wikipedia

Comments Off on INFOGRAPHIC: How Five Building Technologies Bridge the Gap

We tend to take for granted the bridges that bind the world around us, but where would we be without gap-spanning marvels of modern construction? The Ohio University’s Masters in Civil Engineering program put together a handy infographic that lays out five different major bridge designs that we’d be lost without – from the humble clapper-type bridge to the iconic suspension bridge and several in-between.

Snow-Melting Road Salt Wrecks Havoc on the Environment, Infrastructure

Comments Off on Snow-Melting Road Salt Wrecks Havoc on the Environment, Infrastructure

Road salt photo from Shutterstock It’s been a particularly harsh winter for the Eastern United States, and many local governments have exhausted their stockpiles of salt used to melt ice on roads and sidewalks. Salt makes streets safer to navigate when conditions are treacherous, however there are big drawbacks when it comes to infrastructure and the environment. According to a report on Treehugger , salt adversely impacts wildlife, plants, water and soil when it inevitably finds its way into the groundwater, rivers and streams. Road salt can also contain chemicals like sodium ferrocyanide and ferric ferrocyanide , it’s corrosive, and it speeds up the deterioration of infrastructure – every dollar spent on salt costs an estimated four dollars in repairs to roads and bridges.
