I head to New York City with a leaf blower to find out what keeps buildings from swaying in the wind and to take a look at one building that didn't quite get the calculation right.

It wasn't just a conversation with a student which inspired his realization that the skyscraper was unstable. The student herself noticed the problem and did all the math to prove it was real. It is fortunate the architect had the humility to recognize his mistake and solve it even when it was brought to him by a student.

8:46 I have always herd that an engineering student, Diane Hartley, was the one who discovered the design flaw with the building and not LeMessurier. The Wikipedia "Citicorp Center engineering crisis" has a more detail. I am really curious about the your source on the repairs not being need. Over all you have a really great channel and video, thank you.

I was just in NY visiting my sister and somehow I was reminded of 601 Lexington, and I shared the “cliffs notes” version of that story. We ended up passing by the building just by chance, and I must say, it’s surreal to see a building of that size supported by columns like that. Even though you know it’s definitely safe, something deep down tells you it isn’t.

It wasn’t even the architect’s mistake though. The steel contractor changed the design from welded to bolted joints to save money, which weakened the structure. Additionally, the story about the students is a bit more complicated then what you said. Diane Hartley, the student you are referring to, did question the building’s design, but was assured by the architect that the building was fine; however, her questions led the architect to discover the design change. Later on, the architect was having a conversation with Lee DeCarolis, the student the video refers to, which, when combined with Hartley’s inquiry, convinced the architect to recalculate structure, which allowed him to discover the danger.

It's always great to see fluid dynamics topics covered in any kind of science communication. I especially love that you used amateur CFD in a YT video. I am a bit too young to make this comment, but for those a few years older than me, if you went back 15 or 20 yrs and told them that CFD would be so advanced and accessible that anyone can run a relatively informative model on their laptop and that someone causally did so to explain a point in a youtube video, they would be absolutely floored... also you'd have to explain what a laptop was and what a youtube was, but that's besides the point. The point is the capability you showed was just a twinkle in some researchers' eye even 15-20 years ago. Totally wild to see how far it has come. Can't wait to see where it goes. Maybe in 15-20 years, instead of needing 2 months and 20,000 cores of a supercomputer to run a multiphase simulation of a rocket engine injector, I'll be able to do it on my phone in a few hours... For a bit of context, I am PhD computational fluid dynamicist from JHU, and a professional multiphase fluid dynamicst and propulsion engineer with NASA... no question that any critique I have for this video would be dramatically over judgmental, and needlessly critical. Of course this wasn't made for me, and hopefully it was a nicely informative discussion for lots of viewers. The more people interested and excited by the wonderfully silly, counterintuitive, often spectacularly beautiful world of fluid dynamics the better. So instead of critique, I have a hopefully helpful suggestion regarding attribution. It's usually considered best practice to refer to a known fluid dynamics phenomenon (or really any physics phenomenon) by it's wildly accepted name, if it has one. Especially if that common name serves as attribution for the original scientist who discovered it (which it often does). To be clear, this is absolutely not a question of plagiarism or anything remotely along those lines, the ethics of this video are perfectly fine as far as I can tell. I think it's more about respectful attribution of profound scientific achievement, even if it's just through a simple common name for a regularly observed phenomenon. Based on the info in your bio, I am certain you the author already know this, but for anyone else reading along: Just as equations are named for people, so to commonly observed phenomena are named for people, as are fundamental non-dimensional numbers, and lots of things in science. In this case, the particular flavor of vortex shedding you showed is typically called Karman (or Von Karman) vortex shedding, which creates a Karman vortex street. Not that you're expected to give a history lesson on Theo von Karman (or Vincenc Strouhal for that matter), just including the name the first time you reference it is generally considered best practice even in conversational, informal contexts. I don't think it's super important, but I do think it's nicely respectful to attribute credit to the brilliant fluid dynamicists, physicists, and mathematicians who came before us. After all, we stand on the shoulders of giants. I think others might be a bit more militant about this than I am. For me, it just sounds... idk, vaguely "off" I guess. To hear "vortex shedding" (i.e.absent named attribution) in this context when it is very obviously a named flavor of vortex shedding and when presenting to an audience that is definitely not expected to know you are obviously referring to Karman vortex shedding... it's not like "un-cited reference" off, but just... slightly off, I guess. Anyways, it's super late, and I've been up refereeing proposals for several hours. So my critical editor/referee hat is probably on way too tight, and I'm certain I'm being needlessly nitpicky. Great video, love the topic and the way you covered it, and just a friendly note that some people don't like it when you introduce new people to scientific discoveries without attribution... I didn't really think I was one of those people, but here I am writing this comment, so go figure.

Actually, when LeMessurier redid the calculations of his original design, they were fine in the diagonal winds. But someone in Citigroup had the builders use bolts instead of welded joints. For perpendicular winds, this was still fine, but now the diagonal winds were a problem because the bolts were not the best kind of joints, but a cheaper (and easier to fabricate) design.

Correct! Apparently the student's original critique of the building being unstable was misinformed, but then that prompted LeMessurier to do his own analysis after also finding out his original design wasn't implemented in the way he intended (bolts rather than welded from the get-go, thus making it weaker). How much of that is actually true vs. "very smart engineer not wanting to admit a random student spotted a mistake" is debatable though.

A concrete design professor of mine in architecture school gave a lesson on a still existing major security risk with the structural design of 601 Lexington. Unfortunately, there’s no way to publicly talk about it without getting on some watchlists, even though the issues with it aren’t exactly secret… That said, it was quite the eye opener about how to design to protect against wind load _and_ terrorism. We live in a post-9/11 world, so those are considerations that we’re taught about during our schooling now. Anyways, this building is innovative in its design, but has had some serious issues with it. And it potentially still does depending on who you ask.

I know I'm a year or two late to the comments here... but just wanted to mention that you don't really have to travel all the way down from Boston to NYC to find skyscrapers with interesting histories of engineering issues! We've got our very own John Hancock Tower (technically just called 200 Clarendon Street since 2015) right here in Boston's Copley Square. 😉 Back in the 70s, engineers at MIT apparently built a scale model of the tower + the entirety of Back Bay, and tested it in the MIT Wright Brothers Wind Tunnel to figure out why the 500lb window panes kept crashing hundreds of feet down to the street in high winds. As part of the fix, the entire 58th floor was converted into a huge tuned mass damper (à la 7:34) weighing hundreds of tons. Even today, if you stand in the middle of Copley Square and look up at the tower past Trinity Church, you'll see it as a row of windows three down from the top of the tower which appears to be missing. I for one would love to see what that tuned mass damper looks like up close, and learn more about how it works... You think they'd let you up there to make a follow-up video? 😄🤞🙏

For those wondering, the answer is that they're heavy, strong, shaped to reduce wind loads, and can absorb wind loads elastically. I did a quick calculation for the Empire State Building. If treating it as a completely rigid object, the wind would have to blow around 400mph to make it fall over. This only takes into account the fact the building is extremely heavy and it would take a massive amount of force to blow it over. Hope that saves 10 minutes!
