- 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.
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?
The random animal chilling underneath it 100 years after human extinction: 💀
😂😂😂😂😂
Probably tom
THINK FAST CHUCKLE NUTS...BONK
😂❤
Masha Allah
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."
They will assume it was for religious ceremony and human sacrifice. If I know archaeologist.
Nahh, balls are human things, the aliens have their triangles
😂😂@@I_See_you.
"humans used to worship ball shaped gods" 😌
can't believe people don't realize that the pyramids were built to prevent the earth from falling over during earthquakes 😞
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.
Same
It's too big for my mind to comprehend
(That's what she said)

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.
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.
And it's also on display?!?!?!!
That is the coolest fact about this whole design. Incredibly cool that you can see the weight counteracting the external forces!
It's even got its own mascot
It’s so amazing how much flexibility these building have. Engineers are badass
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
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
This is why I pursued enigneering. Things like this amazes me.
I luv these simplistic style videos where they explain engineering, science and physics
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
Ballast.
Cavitation is when air gets trapped behind the propellers/impeller and cause free spin without thrust.
The technology was quite famously used by Renault in their title winning 2005 and 2006 Formula 1 cars before it was banned. It made the cars so much more predictable over uneven terrain.
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
Takes me back to 2nd year classical mechanics on damped vs undamped oscillators. Simplest solution is always the best 👌🏼
It takes huge balls to design something like this.
Nah just huge ball.
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.
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
thanks for the help! ive been wondering where my other one went.
Technically. The ball is trying to stay at rest. The building starts to sway but the ball works as a brake by trying to stay on its original location. The only force (aside from gravity) working on the ball is the building swaying. There will obviously be some residual swaying due to the force of the swaying building on the ball.
The engineering behind Taipei101 is truly impressive. The tuned mass damper is a genius solution for preventing sway from wind loading.

This reads like a student who was forced to make a comment on taipei101 for credit

What kind of fake ChatGPT ass comment is this? Thank you for contributing nothing.
Chicken leave me alone please I’m begging you
This is actually so smart
Thanks
@@Vastfill much appreciated
@@Vastfillhe is not talking about you?
Thank you
@@fishfish248 you're welcome
Imagine being in the building and hearing it fall hitting each floor one by one just waiting for it to reach you
I learned that this existed as a kid and have been obsessed with the building ever since I would really love to go see it in person
I actually saw the ball while in taipei visiting relatives its just as cool in person
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
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.
You know, I normally only type a reply when the video doesn't answer its question, but I wanted to drop a comment because your video did answer its own question, wasn't click bait and I learned something new. Nicely done guy
I learned about this from Artemis Fowl, such a fun series.
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
Eyeball licking goblin, like
It is impressive that the building can support so much weight.
The top-heavy thing is somehow more stable. This works because heavy things resist motion.
aka inertia
Everybody gangsta till the ball busts through the ceiling 😂
Edit: Wow! So many likes! Where do I start? I would like to thank my parents for raising me. TH-cam! Without you guys nothing would be possible, My wife shirley, all her support made this possible. Thank you god, for all you have given me...and last but not least I would like to thank you, the likers!
Thors hammer 😂
@@mugojr4766 imagine the sound it would make hitting the ground
What I was thinking too 😭
Busts
@@eltipobigotudo2162 what?
I’ve been looking for this kind of post. I was hoping for actual footage of the ball during the earthquake.
Protecting buildings from swaying really takes balls.
They hung a 730 ton ball in middle of a skyscraper and people say we couldn’t build the pyramids today 🙄
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’ve been there. You can actually go up and see the ball inside at the top of the tower.
I also had one of the best meals of my life there
Imagine hearing the ball crushing through the floors 10 floors above you
Imagine it starts swinging in the same direction
inertia would need to cease existing
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.
I actually went to this building a couple months ago. It was amazing to see a huge ball.
Imagine ball colliding with interiors
I love these ingenious engineering techniques.
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
My understanding is the US embassy in Mexico City has an earthquake prevention system also. Of course it is not as massive as the tall building, but it was built way back in the 70’s and has survived many earthquakes.
Not sure when the system was built, but I do remember becoming aware of the system in the early 70’s.
how engineers come up these is amazing
Damn, that's about a quarter of CaseOh's weight
Youre too generous, it's about 2% at most
BANNED
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 why roof top pool is good for structure, no only design
It’s scary to think that these buildings that feel so rigid and solid to us are actually swaying while we are inside of them.
This is great, you’ve got yourself a new subscriber😁
The building got balls of steel I see !
*only one ball
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
I visited this building last year. Amazing engineering
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.
💀
Balls keep me stable as well. 😅
😂 two instead of one
That building got some serious balls to withstand the earthquake among natural disasters.
god i remember that mission from medge catalyst where you destroy a tower by releasing a tuned mass dampener coolest mission in the game
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.
The sphere was designed and built by a company based in Padua, Italy
PS: however the concept was not new @corneliusdinkmeyer2190
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
One of the older Renault F1 cars also had this system. It was placed at the nose of the car and greatly helped the car to remain stable when riding the kerbs on the track
Well, it doesn't "swing" to the other direction: It stays in the starting position until there's enough force to beat inertia and that point is sharply calculated with the needed mass of the steel pendulum to match the next swing (although the secondary inertia action would somewhat match up, it will have incredible wear and tear plus it won't work as good and could perhaps cause structural damage which obviously will lead to lethal outcomes) so yes, it does swing in the eyes of the observerer but to call it an absolute swing is rather absurd in the sense of physics behind the mechanism.
"Our buildings are STRONG! Massive balls!"
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
When there's an earthquake, people may be terrified, but the building has a ball.
that would freak me out seeing how much the building was actually swaying
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
Everybody gangsta till the narrator says "200 years after people."
They have interactive models showing how this works at the Science Center in St. Louis. Very cool to learn about! I knew what you were referring to as soon as you mentioned the ball.
They actually have a crew of magicians down there that help stabilize the building when an earthquake hits.
Italian engineers are the best 🇮🇹🇮🇹🇮🇹
William LeMessurier was an American Structural Engineer.
I think they are referring to the fact that the sphere of the Taipei 101 was designed and built by an Italian company@@HubofLovin
Meanwhile the other buildings in Taiwan fall without even the wind blowing in it's direction
Only 4 buildings fallen tho
"natural movement of the building" got me chills
I was there two weeks ago and I read that the mass of the steel ball is 660 tons.
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.

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.
Imagine the weight of the yellow 730t ball has to be factored into the strength -and therefore, material used for the building.
Damn that building has balls of steel.
Crazy. That's one ball you never want to see drop!
The fact that we can even just lift 730 tons so high up is insane
Got to admit this is some ingenious engineering
I designed a building for my architecture class that was 300’ tall to scale. I put a counterweight on the top with base isolators at the bottom as well as a central column that was isolated from the rest of the building. It got put on an earthquake simulator and I won second place, my tower stood just fine. Counterweights are awesome 😎
I’ve been there and the ball is actually massive
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.
You could slap a coil around that and passively generate power. There are wobble windmills that work like this
Lowers the centre of gravity resulting in less swaying..the weight dampens the momentum ❤
I can't imagine how loud or how big the crater would be if that steel ball fell.
This looks like something in a movie that would cause a catastrophic failure.
Bet this guy couldn’t beat the bridge building advertisements I see
Human ingenuity is truly extraordinary.
I kinda learned about this in an Artemis Fowl book but it’s cool to see some more about it
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.
Ohh wow ,this simple harmonic motion's application is interesting
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
Seems like there would need to be a nonlinear modal analysis done to figure out which mode is the worst for each story and they’d need to model it for different ball mass iterations.
What would be the risk if the ball fell from the ceiling one day?
I remember reading about this thing in Artemis Fowl
I had seen that before but always wondered how it worked thank you!
