Ever wonder how many castle walls fell over during or shortly after construction because the architect was playing it by ear and could not do detailed calculations? "Not only is Leonardo's design structurally stable, but the structure is the architecture.
“It was about 10 times longer than typical bridges of that time.”The design also featured an unusual way of stabilizing the span against lateral motions — something that has resulted in the collapse of many bridges over the centuries. But yeah, it would have been nice to a bigger model at 1:10 scale such as 79 feet for the modal.Keep in mind that the span and length are two different numbers.A 79 foot long model would have been cost prohibitive for a grad project.
“It’s incredibly ambitious,” Bast says. Jennifer Ouellette - Oct 16, 2019 …

“What we can learn from Leonardo da Vinci's design is that the form of a structure is very important for its stability," explains MIT alumnus Karly Bast.MIT researchers developed a 3-D model of a bridge designed by Leonardo da Vinci and found that “not only did it work, but it would have also revolutionized bridge design five centuries ago,” reports Andrew Liszewski for This Website is maintained by the MIT News Office, part of the Proposed bridge would have been the world’s longest at the time; new analysis shows it would have worked.American Academy in Rome appoints John Ochsendorf as 23rd directorCEE students build model Guastavino vault for exhibit In a recent study, Michelle Xie BArch ’19 and Karly Bast MEng ’19 worked with Building Technology professor John Ochsendorf to discover that a bridge proposed by Leonardo da Vinci over 500 years ago would have been the world’s longest at the time. “This is a strong concept. Once the final keystone was in place, the scaffolding could be removed.
Nearby there are some ruins of their houses. “He knew how the physical world works.”He also apparently understood that the region was prone to earthquakes, and incorporated features such as the spread footings that would provide extra stability.

Ultimately, the team built a detailed scale model to test the structure’s ability to stand and support weight, and even to withstand settlement of its foundations.The results of the study were presented in Barcelona this week at the conference of the International Association for Shell and Spatial Structures. “It was about 10 times longer than typical bridges of that time.”The design also featured an unusual way of stabilizing the span against lateral motions — something that has resulted in the collapse of many bridges over the centuries. But “when I put the keystone in, I thought, ‘this is going to work.’ And after that, we took the scaffolding out, and it stood up.”“It’s the power of geometry” that makes it work, she says.
The following 10 research-related stories published in the previous 12 months received top views on MIT News . Modern construction is largely based on architects thinking the entire world can be suspended on invisible skyhooks, and engineers which attempt to make do while working out a design to incredibly tight tolerances.Ancient engineers were missing two things: strong materials which could be used in tension like steel and the math to make use of them. No metal nails.
This natural river estuary separated the cities of Galata and Istanbul.Da Vinci's proposal was not selected. "Ten times as big" is one thousand times as much material. We use the same amount of lumber for building forms to make modern concrete structures.If you are going to build that much scaffolding might as well leave the scaffolding up and run a road on top.Wood isn't durable. The solution is to extend the arch into the ground until the foundation hits rock. The bridge showed resilience to the horizontal movement, only deforming slightly until being stretched to the point of complete collapse.The design may not have practical implications for modern bridge designers, Bast says, since today’s materials and methods provide many more options for lighter, stronger designs. But, I will add another set.Just because it works on a scale model doesn't mean it would work in real life.The whole history of architecture has depended on models and drawings to plan and engineer the real structure, and then the real structures stand for centuries or millennia.
