- How a 730 ton steel ball protected Taiwan's tallest skyscraper, the Taipei 101, from the recend 7.4 magnitude earthquake. Structural engineers used a tuned mass damper system that counteracts the swaying of the building.
The random animal chilling underneath it 100 years after human extinction: 💀
😂😂😂😂😂
Probably tom
THINK FAST CHUCKLE NUTS...BONK
There will be no biological being left after human extinction, only our successors of steel.
😂❤
One could say the building has balls of steel
the building has ballroom right
Get out
ball
It's the Lance Armstrong of steel balled buildings.
Just 1, just 1 ball. I have it's (well, not quite) other steel ball hanging from the rear view mirror of my massive car. Among with my fuzzy dice. Any gamblers?
Steel Ball run live action seems great
I was just scrolling the comments to look for a JoJo photo lmao
@@cdenialsbro same whenever a steel ball is mentioned in a video I can’t help but search through the comments to try and find any Jojo fans
@@chingambit88 yeah, I just saw an “Eclipse” post and I went to the comments to find any BERSERK related comment, and I found some hahaha.
@@cdenials most of the posts about the eclipse i saw was about people wanting to attack the fire nationg from (atla) lmao
STEEL. BALL. RUUUUUN.
I’ve seen this in person before. It somehow gave me chills at the time
In person it really feels different than watching it on the screen
One day I might pay a visit again
Ummmm First off, so cool to hear! Second it’s absolutely terrifying to see in this clip. How I’m the hellnis that just chills! I’m FREAKED when I see the inside of ships ballast tanks ( I think those are it) full of water and raging like some horror movie.
Important to note. The TMD on Taipei 101, actually has its brakes activated during any significant seismic activities as the excitation would be too great, it’s primarily only operational for heavy storms and minor earthquakes, but actually doesn’t contribute to any comfort in sizeable earthquakes
I just love it when there is a good correction bellow a video like this :)
I wanted to say there is also a dampening device there, so its not just swaying of the mass
This building is doom once a 9.0 hits taiwan is in the area known as the ring of fire
So you’re saying it probably didn’t help at all during the recent 7.4 earthquake?
My first thought was what if it’s too large or a seismic event and the TMD ended up having the opposite effect, aiding in self destructing the building instead of helping
@@brandonmeens The brakes only restrict the range of motion and increase the amount of force required to move the ball. It still functions during earthquakes, just it's less effective at reducing wind sway while doing so.
Approximately 5.5 meters in diameter, the damper consists of 41 layers of 12.5 cm solid steel plating welded into a gold sphere mass, weighing 660 metric tons.
why gold I wonder..
@@hannibalb8276extremely dense, so more counterbalance
@@FailedLobotomyPatient If density was the issue, they'd use lead for this, gold is way too expensive. I think they were just referring to the colour.
@@FailedLobotomyPatient how sure are you that it failed
Thats a large ball
Same technology is used in cruise ships but with water, they move the water that store in the ship from one side to another during storm to counteract ships movements side to side.
cavitation right?
Not sure with that water that you are saying. Yes there is water ballast tank on all types of ships, i guess an estabilizer is equipped on cruise ships. But in Marine engines, it has what they call compensator it is equipped in the Engine to reduce vibration during, especially at rough seas
And I'm likely the only human being thinking, "What happens if it falls?"
Did you ever watched a sykscraper collapsing fromt the top to bottom? I saw twice.
Im thinking, what if the ball swings too much and hits the building?
That hits deep 😢 🤧🫡@@mr.hierkonnteihrewerbungst8555
It won’t
I’m a bro form tw.
Ask a 25 year old from NYC, they got 2 examples to show you.
Motioneering did NOT engineer this TMD for earthquake resistance, it is strictly designed to prevent sway from wind loading. It may have a residual effect in earthquakes but that is not what it was designed for
So it's not effective against earthquakes of high magnitude (6.0 up)? Will it worsen the sway during such strong earthquakes?
@@testsalv4366 it would never worsen the sway. It will still have a positive effect in strong earthquakes, but the engineers have a separate seismic force resisting system for the structure.
Yapping
@@bensblues Okay, thanks for the answer.
@@bensbluesso why tf did you bring it up if it helps with earthquakes? That's exactly what the video said
Always been impressed by the engineering behind Taipei101.
P L A N E
The Chinese are quite good at engineering
@@Oferdrincerewhen given a reasonable budget
@@user-xh4xg1jf8c They actually became known known for it and seem to be pretty good at engineering at low cost too…
@@Oferdrinceretoo bad, structural engineering was done with the help of a Western company lol
It’s so amazing how much flexibility these building have. Engineers are badass
Fun fact: Taipei 101 is also modeled after bamboo structure which is inherently strong, and during its construction survived an earthquake with only minimal damage. It is one of my favorite skyscrapers from an engineering and architectural perspective.
They should have a live stream of that ball 24/7/365 it would be very cool to see a video of it working in action depending on the magnitude
That one Artemis Fowl book makes a lot more sense now
Immediately thought of Artemis Fowl when I saw this video
A fellow Artemis Fowl reader I see
Yeah but wasn't this supposed to be silver or something
@@piyushsawant5394 it’s supposed to have a silver jacket around it with engravings

The tuned mass damper work so well that back in 2006 renault f1 team use it in their cars. If u find footage of the cars driving over bumps, you'll notice just how smooth it rides over it
I was searching for this EXACT comment
as soon as I heard tuned mass damper, I immediately started looking for F1 fans lol
I fucking knew it, someone would definitely mention F1 here.
Was looking for it too!!! Love it.
Here he 8s
Thanks. I wondered about the buildings as I watched the earthquake online.
It takes huge balls to design something like this.
Nah just huge ball.
that explains a why a game i use to play had one of these! saints row 2 syndicate tower had a ball (tallest tower in game)
Saints row the third lol
Yea, that was SR3(classic/remastered)
Welcome to Control Theory.
Its like one of the last chunk of things you learn in engineering school. Its starts at around Junior Year or Senior Year.
I remember when that building was being built and there was a lot of press over that damper for being the largest of its type in the world and mounted so high up.
Very nice to see it continue to work so well.
F1 cars used a tuned mass damper back in the early 2000s- pretty cool to see it given a practical use
I’ve been looking for this kind of post. I was hoping for actual footage of the ball during the earthquake.
I love these ingenious engineering techniques.
I visited this building last year. Amazing engineering
The engineering behind Taipei101 is truly impressive. The tuned mass damper is a genius solution for preventing sway from wind loading.
By Italian engineers
This reads like a student who was forced to make a comment on taipei101 for credit
ai generated ahh comment💀
What kind of fake ChatGPT ass comment is this? Thank you for contributing nothing.
Chicken leave me alone please I’m begging you
I would just be scared of being under that ball because what if the chains holding it break
It's not held by chains, rather suspended by hydraulic arms
+ in addition the the hydraulics underneath there are steel cables holding it up so if the arms were to fail those cables would catch it. You can see them in the video
There’s overstrength factors used for critical components of seismic force resisting systems that multiply the force the components are designed for. Basically saying hey, if it has X amount of force on it actually, it needs to be designed for Y times that amount of force. So lots of redundancy and safety in the system.
Obviously, the people that built knew it was a massive ass ball...and accounted for it. smh
@@rachel705
Those hydraulics are what brakes the mass, there is no way they support it.
Imagine it starts swinging in the same direction
Humans who find that ball 10,000 years from now:
"We have no idea how this massive ball was produced or even what it was used for, so many believe it was created by aliens."
I actually saw the ball while in taipei visiting relatives its just as cool in person
This is great, you’ve got yourself a new subscriber😁
730 tons is crazy😮
Thats 1.5x more than the legal takeoff weight of the worlds biggest passenger plane
Its not crazy for a skyscraper that weighs thousands of tons, dozens.
That's fascinating! I bet it's difficult calculating the mass of the ball, too, because you have to calculate the natural frequency of the building under different wind speeds and earthquake magnitudes.
I learned about this in my vibrations class in college. Crucially, the ball is not a simple pendulum, it's mounted in place with a system of springs and dampers. The mass of the ball and the parameters of the springs and dampers are _tuned_ to match the resonant frequencies of the structure. This is done to prevent the building's sway from resonating with the oscillations of any applied forces, by transferring that oscillation into the ball.
Damn, that's about a quarter of CaseOh's weight
Youre too generous, it's about 2% at most
BANNED
Neat videos. As a California engineer you probably don't have a lot of experience with hurricanes or tornados although you mention wind forces very often in your videos. Tsunamis (from earthquakes, hurricanes, nuclear explosions, etc) are catastrophic forces that maybe builders might consider too. In the 1992 Hurricane Andrew in Miami much of the building damage came from developers purposely evading building codes and not including joints tying roofs and walls together as well as other requirements. These are good videos for me a non-engineer.
California is one of the most seismically active states
God I love the elegance of simplicity
Good engineering applied practically.
Well done
The building got balls of steel I see !
*only one ball
Renault used a tuned mass damper years ago in F1 to increase grip on the front tyres
In short yes, but in detail, it was implemented to make the car more stable at bumps which allowed them to lower the car further which improved tyre grip
Nice, concise and informative video!
Tuned mass dampers are amazing, they're not just used in this situation.
They're everywhere that vibration is an issue.
I have a 21yr old car, do my own maintenence and repairs, and there's quite a few. Just weird cubes of steel, insulated by rubber and mounted to something that has some vibrational resonance complaint.
Balls keep me stable as well. 😅
😂 two instead of one
I tested this in the shower. I swayed left, and my steel balls seemed to deflect right relative to my body. I went right, and the seemed to go left. I can't say if it controlled my sway, but I am happy to keep trying, perhaps with more balls.
💀
The simplicity of ingeniously designing su ch a system is beautiful
Can't wait to see what damage it wreaks when it falls after breaking.
Also, others have pointed out this is NOT used in (at least heavy) earthquakes, they lock it down.
So at that point wouldn't it be making things WORSE for the building with a giant weight added above it's center of mass?
I would assume they have this thing built on a serious "skid pad" to compensate for the earthquake situation.
My dad actually helped design this by designing the cables and brackets for the damper. He was part of an engineering firm in Ontario that got commissioned to help the original firm with designing it.
That’s very cool! I was wondering who came up with this idea.
It reduces sway, but does it reduce or add tension? Basically yanking the building back to position from the top
Stress is proportional to sway. So if you reduce sway, you reduce stress
Its a passive mass spring damper basically, probably designed for natıral frequency of the wind
I learnt about this in school... It's not just this building but most skyscrapers have this.
"Our buildings are STRONG! Massive balls!"
Italian engineers are the best 🇮🇹🇮🇹🇮🇹
William LeMessurier was an American Structural Engineer.
The Tuned Mass Damper is also found in some tall buildings, which helps it when in earthquakes and typhoons.
As i recall a similar damper system was in an old theater in one of the Clairemont McKenna Colleges in California. Sometime in the 1970s they felt the need to destroy the old structure because it was not seismically safe. They went into the attic…and found a series of counter weight pendulums created out of huge stones. The structure was saved…and hopefully though it has been 50 years since i saw it…it is still standing.
It may act in low frequency, but in case of erratic high magnitude waves.. it can be disastrous in case the earthquake wave harmonize with this pendulum.. may bring the building down in seconds
American would never have this much preparation. Taiwan was hit was an even heavier 7.7 mag earthquake 25 years ago and they mandated that ALL buildings were built up to earthquake resistant code. the fact that they're only sitting at 10 casualties with such a dense population is insane
Because america never gets hit that hard by earthquakes? California is basically the only part of America that's at any severe earthquake risk, and there hasn't been a severe earthquake in 30 years anywhere in north america. And that last one was only a 6.7
California has been building with earthquakes in mind sense the big one (7.9) in 1906. 3,000 people died. When the Loma Linda (6.9) hit in 1989, 63 people died. We have quakes here every single day and Cali is about 10x the size of Taiwan. I think we are prepared.
Actually there's a comcast skyscraper in Philadelphia with a water tank at the top. It acts much like the pendulum in that it's meant to counteract forces that sway the building. It's designed for wind but should also work for earthquakes. This is not an uncommon solution either in America, They're called sloshing dampers.
shit in america for no reason ok ok ok
You need to check out the building codes in San Francisco.
Great demo
I’ve seen this in person and it’s really impressive! And so is viewing down from higher floor observation decks…. Amazing! Clouds below you!!
Meanwhile the other buildings in Taiwan fall without even the wind blowing in it's direction
Simple words, it functions like an anchor.
No it doesn’t
@@russelldawkins9094 explain it then. Literally functions like an anchor or it somewhat functions like an anchor.
Anchors or heavy balls protect structures from swaying at it adds weight which takes advantage of gravity to pull the building down making it artificially more heavier and having more force to the ground means it will have less sway.
If your brain doesn't understand imagine you pushing something like a lego tower downward. No matter how much you blow it, it doesn't sway easily because there's a stronger force pushing it down than the Force pushing it horizontally aka the wind.
If we're talking about earthquakes
Imagine Panzer 8 Maus a 188 ton behemoth one of the heaviest tanks to ever existed compared to a human like you for example, no weight because of the lack of brains and when it earthquakes you move more or you sway more as you are more lighter and your mass is smaller than the Maus. THAT'S LITERALLY THE BALL being an added weight to the building.
Anchors functions somewhat the same at it make the ship stay in place to prevent it from going anywhere.
That huge ball functions the same it adds weight. So the building won't go flying on the air. Is basically an alternative to joints.
If you have a better explanation do so I dare you.
If not then stop.

amazing illustration 😮
Caseoh protecting the skyscraper from his own earthquakes is so noble 🙏
Human ingenuity is truly extraordinary.
When my class was seeing video from the recent taiwan earthquake, a building under construction seemed to be taking a lot of damage (super short clip, so hard to tell). this led to a discussion on counterweights for earthquakes..
That’s why roof top pool is good for structure, no only design
It's called a "counterweight."
The first counterweight, used to balance and counteract the effects of gravity, first appeared around 1670.
Ohh wow ,this simple harmonic motion's application is interesting
Thank you Newton!
I remember reading about this thing in Artemis Fowl
renault used a smaller scale version of this in their 2005 & 2006 f1 cars to reduce the vibration when going over the kerbs in corners making the car more stable and providing more consistent levels of grip also one of the reasons they won the championship those 2 years
Wonderful reaction of engineer
I got to see it in person and it's MASSIVE
That's really well designed. It's aesthetic and functional. Nice.
I actually had to do a school project on earthquakes recently and I decided to use taipei 101 as an example of how people have to adapt to these earthquakes to were they live
The visual is great
It’s fun seeing designs I studied and replicated in high school being taught on CZcams shorts lol
the engineers are amazing
That’s a very useful and cool video. Thank you.
I get to go on one of those skyscraper and see and really took in at how massive the core is
Honestly its amazing how it all works
It has a self-destructing top to bottom wrecking ball built in.
I remember seeing the 101 when I was very young, core memory for sure. Leaning up against the glass looking at the thousands of mopeds lol
It’s the resonant frequency that destroys structures during an earthquake, and a pendulum is perfect for maintaining equilibrium in the compressive engineering of reinforced concrete structures.
That’s an impressive ball bag. They look like low hangers.
Perfect showcase of why engineering is absolutely awesome
I've always wondered this about really tall buildings.
In Mirror's edge catalyst you had to parkour climb one of these buildings (that was being built) in order to drop the tuned mass damper through the building to destroy it lol
Lowers the centre of gravity resulting in less swaying..the weight dampens the momentum ❤
Whats most amazing to me about this is the fact its JUST a lump of metal. No electricity, no motors, nothing being burnt or fuel being expended. Just the laws of physics.
This kind of civil Engineering blew my mind. Although I study Electrical Engineering, this video is still informative.
This is CRAZY engineering, so awesome
Its amazing to know how balls can make so much differance
I actually visited this steel ball some years ago. It's a pretty nice tourist attraction(had an arcade nearby too)
And the long shock absorbers burn off the energy of the moving mass as heat, much like the brakes on your car burn off the car's moving energy in the form of heat. This is where the "damper" term comes from. The all-spring example in the video does not add any kind of damper, resulting in more motion than you would see if there were a way to add some simple shock absorber to it.
