I would point out that it never ‘sleeps’. The tuned mass damper is not just there for earthquakes. Its primary job is to dampen the swaying in tall buildings that is induced by winds. In Taipei, that is particularly needed because of Typhoons. The force of wind on an ordinary blustery day on skyscrapers is significantly greater than you might imagine.
The winds where what doomed the (albeit somewhat goofy) concept of Airships docking to the Empire State Building. Sounds easy enough to dock to it in a hypothetical, but once you have STRONG winds…not happening.
@@ericlotze7724 That, plus the fact that if there was a storm front or other large change in barometric pressure that swept thru while it was moored to the Empire State Building, that the airship would swivel down and crumple itself against the building, raining debris down on the people in the streets. Or swivel straight up and try to pull the spire right off the top of the building.
Agreed. The building is round so no matter the direction from the epicenter, it will damper. I was in a 5 story apartment in Philippines when a quake hit and it whipped the building because the building was long and the quake hit on the broad side. Another apartment nearby felt little as it was long ways to the epicenter

They are in a skyscraper. It’s not as if they could possibly have gotten OUT of the building in the time the ground was shaking. But more to the point, Because of the mass damper, the building was not shaking nearly as much as the ground, and so to the folks inside the building it felt like a very minor quake.
Perhaps more than any other structural invention, the tuned mass damper epitomizes parsimonious and elegant engineering design. Consuming no power at all, it simply sits there, passive and stationary for years on end, until needed, then dutifully springs into action at a moment's notice to do its job, then back to sleep for another untold age.

@@cosmictyger There's no point. It only moves when there's an earthquake. There's no point in designing something like a "regenerative break" when its only used once every 20 years for a few minutes at most.
That TMD is part of the reason that building wasn’t reduced to a pile of rubble. Now to comprehend the sheer amount of force it took to make that giant thing sway around like that!
@@FrontSideBus You are correct. Exactly that, The TMD is remaining closer to stationary and applying force to the structure to reduce its motion. This is what dampening is all about. Source: Me. Practicing civil engineer for 40 plus years.
Well technically inertia is the opposite of doing something. In this case the ball is doing nothing it just wants to sit and not be moved. It's pistons that are doing all the crazy work
What may have been missed here, the damper is mostly stationary. The top of the building is moving around it and the damper is slowing/minimizing that movement so things don't shake apart.
Yes and no. The damper is more or less stationary in relative to its original place in space but is moving opposite in relation to its place on the surface of the planet.
Now thats architecture done right! Both functional and beautiful. They could have made it a plain lump of weights and hidden it in a closed room somewhere. But no, they found a way to make it into something attractive and interesting whilst still performing a critical role in the structural safety of the building. Classy! 👌
When I visited Taiwan in 2013, I visited Taipei 101. I saw this ball too. I thought it was only for a show. Only realized now that it is a scientific tool use for dampening.
I think it is more complex. I think the mass is being swung up by the building while it shakes and the dampener leeches on that energy warming the dampeners.
@@simontautorat1014 building is not shaking, at least vertically, but swaying horizontally. Earthquakes don't usually push up, and I've been through several in Vegas, LA,and Hawaii.
Simple answer is yes. Technically the ball is attempting to stay stationary "mass at rest, tends to stay at rest" while the building moves around it and the huge shock absorbers limit the motion and shock. That was amazing to see it actually work!
Taipei 101 is the coolest skyscraper out there. The look and design is just really impressive, but it's also great to have a safety feature like this giant damper swing gently to counteract an earthquake, that's strong enough to level entire cities.

ive always wanted to see it move in a clearer view, thanks! ive actually been there a bunch of times and they played this low quality video of an earth quake that occured in 2015; they should defo replace the footage with this one.
No, the point of the damper is to partially cancel out the motion of the building so it is moved more than the building moves. The damper can't be the same size and mass as the rest of the building so to do its job it is moved more than the building and 180 degree out of phase, give or take a bit. If the damper were insanely big it might prevent the building from moving at all, so what it actually does is limit the peak sway of the building and prevent the building from swaying at particular frequencies that would provide positive feedback. As a 'damper' its job is to provide negative feedback!
@@Raptorman0909thanks for correcting the nonsense imaginations people spew out on a whim without actually knowing wtf theyre even talking about. I appreciate people like you. Total opposite to people like OP..
@@Raptorman0909 The way you describe it makes the damper sound powered. It isn't, it just hangs there, with shock absorbers below to dampen it's movement. it's a dampened pendulum.

The building movement caused the "ball" to move, it moves proportionately to building movement. If the building doesn't move the "ball" is stationary. I believe they knew.

In addition to the other answers, good engineering builds in redundancies so that while you can see four cables on each side, only two or three might be absolutely necessary. This is partially to guard against accidents/poor maintenance/possible defects in the steel itself, but also so that if one cable needs to be replaced, it can be done safely. If worst came to worst, however, the damper could be taken apart more easily than it seems. It isn't solid; it's made of circular steel plates joined together, so it could be dismantled one piece at a time and then repaired or replaced. It would still be hectic, but not as hectic as trying to manage a solid 660-tonne ball suspended on threadbare cables would be.
non è stata fatta in italia, e Vitaliani pare lo abbia solo collaudato. L'azienda che la ha fatta comunque dice invece che non ha nulla a che spartire con lui in alcun modo.
I imagine that very few people have seen the ball moving as much as it was there. I went up Taipei 101 years ago and it’s a great thing to look at, but I’m glad that an earthquake didn’t kick off while I was up there.
@@randomnickify Yes, I found one that "works". Many of these are are so superficial as to be "criminally negligent". ruclips.net/video/f1U4SAgy60c/видео.htmlsi=aPboHMnWhasqHzrt
The Citicorp tower in NY City has one of these, and that was the skyscraper that due to a flaw in it's construction could have fallen over in a wind storm! When the flaw was suddenly realized by the architect, he wondered if the damper would help, but no. The flaw was the diagonal braces were originally to be welded, but the cpontractor asked if he could just bolt them instead and they agreed to the change not realizing that the bolting instead of welding could cause serious problems. They wound up secretly welding all the joints at night and weekends, plastering the holes in the sheetrock back up and nobody who worked in the offices ever had a clue what was going on!
Bolts always have a little bigger hole than the bolt. So a little bit of movement at each bolt, multiplied by all the braces, equals unsafe movement. Welding eliminates the play, then it's just engineering calculations for the load and materials.
@andyharpist2938 Although I don't know that much about riveted aircraft, I do know that a great advantage rivets have over bolts: as you tighten a bolt, tension makes it thinner, so the space between the bolt and it's hole increases. A rivet is tightened by hammering it, so it completely fills in it's hole. So if it's loaded in shear, no movement until failure. So, as a general rule, rivets better in shear loading, bolts better in tension, lengthwise loading. I think rivets are no longer as common because of welding; replacing a series of stress points with a continuous connection. It would be interesting to compare different attachment systems in a high end modeling program, cycle them a few million times and see what fails.
@@EthanPerkins-qq9qh That's interesting instruction Ethan. Bolts do indeed become thinner when tightened . But rivets when driven home must also surely have an " elastic retraction" (that might equal the creation of gaps around a bolt? I know lead is especially good for its almost negligeable rebound..Hardly useful in a structure, but great on a roof.
Taiwanese critical item constructed as designed, and working perfectly. Super impressed with how Taiwan's buildings stood up, and even leaned over - without falling down. Keep up the corruption free construction work Taiwan! Keep it up!
I can't fathom the forces involved here. Even having been in an Earthquake it is still hard for me to wrap my head around the sheer amount of mass moving when it happens. All that ground, water, buildings, everything, all getting tossed around like nothing. If you have never been around an earthquake when they happen, they are a humbling experience. (Read that as this old man nearly poo'd himself when it happened)

I love how they just built a building that can withstand an earthquake of this strength. Being inside, calmly watching the ball swing, it's like "LOL, good try, Earth. Try harder next time.".
I saw that in 2008 (iirc) just after the 101 opened and at the time it was the tallest building in the world. It's an amazing feat of engineering although i didn't see it move. However, I experienced my only earthquake whilst sat in the bar of the Taipei Shangri-La hotel during that trip when I spotted the curtains swaying. It scared the crap out of me because my bed on the 18th floor (again iirc) faced a huge floor to ceiling window and I had visions of me being launched through the window in the bed during the night. I didn't sleep a wink 😬

In addition to the other answers, good engineering builds in redundancies so that while you can see four cables on each side, only two or three might be absolutely necessary. This is partially to guard against accidents/poor maintenance/possible defects in the steel itself, but also so that if one cable needs to be replaced, it can be done safely. If worst came to worst, however, the damper could be taken apart more easily than it seems. It isn't solid; it's made of circular steel plates joined together, so it could be dismantled one piece at a time and then repaired or replaced. It would still be hectic, but not as hectic as trying to manage a solid 660-tonne ball suspended on threadbare cables would be.
Low humidity climate controlled environment? Forever probably
MADE IN ITALY by Renato Vitaliani all-Italian project together with Fip Mec, a company from Selvazzano (Padua)
non è stata fatta in italia, e Vitaliani pare lo abbia solo collaudato. L'azienda che la ha fatta comunque dice invece che non ha nulla a che spartire con lui in alcun modo.
If that wasn’t there that building would be leveled. Very subtle but very important engineering
Really good that ball was swaying instead of the whole building
Technically the building was swaying equally and oppositely..
I don’t see the people moving. It’s as if they feel no quake
.
@@electrictroy2010 They’re probably used to earthquakes
Not really as this is a (anti)-resonant system.
@@markwgundert4251 Yeah the point of that ball is that it stops the building from swaying by swaying itself in the opposite direction
that's a feat of everything
Knowing how much that thing weighs, the fact that it's moving that much, that quickly, is pretty insane
I imagine that very few people have seen the ball moving as much as it was there. I went up Taipei 101 years ago and it’s a great thing to look at, but I’m glad that an earthquake didn’t kick off while I was up there.
The ball doesn't move, it has too much inertia. The building does, that's why it works. It's more impressive in person.
wow this is an incredible video.
Idea: The ball shakes so you don't
Mehhh a better idea would be to just build on more solid ground. NYC is built on mostly bedrock and the buildings are very strong 💪
@@triskits_mmm NYC isn't anywhere near active fault lines. Taiwan is. Big difference.
@@dt99022 So just save up for a plane ticket to NYC and live earthquake free 💪💪 Not that hard. Living is an earthquake zone is dumb.
@@triskits_mmm Earthquake zones are definitely preferable to NYC.
People were awe for ten seconds then back to their stories, like yeah, yawn, another day.😊
Marvelous engineering demonstration!
Did the damper sway? Or did it stay still when everything else moved?
It moves in the opposite direction of the building to cancel out the sway.
You had one job...and you did it really well.
Engineer: ugh! Finally done!
People during the earthquake:
*watches the ball swing*😂
It gets more impressive when you realize that most of the motion is the building moving.
Nice to see it working as intended. So cool that they put it on display instead of behind concrete.
It’s always so incredible to see things like this doing their job
As an engineer ... I find it amazing, but I wonder how they maintain the cables holding the massive ball .... how to do replacement when needed etc?
Oh, that is easy, just put an axle stand under the ball and then remove one cable! I am an engineer too.
Is the mass damper swinging, or is the entire building around it moving…?
They're both moving. The TMD is pulling the building back to it's central position by countering the lateral force being placed on the building.
Bit of both
They probably didn't even know they were going through a 6.8 quake, because everything was stable.
Is there a link to how these things work?
Mass dampener, there are probably hundreds of videos explaining them.
@@randomnickify
Yes, I found one that "works". Many of these are are so superficial as to be "criminally negligent".

People acting as if getting hit by an earthquake is like winning a lottery 😂
How they will change the wire?
The damper is largely staying still, "pointing" straight down. It's the building that is swaying.
Thank you Samsung for building this amazing building.
Worked as planned! Kudos to the engineers!
The Citicorp tower in NY City has one of these, and that was the skyscraper that due to a flaw in it's construction could have fallen over in a wind storm! When the flaw was suddenly realized by the architect, he wondered if the damper would help, but no. The flaw was the diagonal braces were originally to be welded, but the cpontractor asked if he could just bolt them instead and they agreed to the change not realizing that the bolting instead of welding could cause serious problems.
They wound up secretly welding all the joints at night and weekends, plastering the holes in the sheetrock back up and nobody who worked in the offices ever had a clue what was going on!
why would bolting be less effective than welding?
Bolts always have a little bigger hole than the bolt. So a little bit of movement at each bolt, multiplied by all the braces, equals unsafe movement. Welding eliminates the play, then it's just engineering calculations for the load and materials.
@@EthanPerkins-qq9qh Thats interesting. As a Civil Engineer myself I had not heard of this. How about riveted aircraft?
@andyharpist2938 Although I don't know that much about riveted aircraft, I do know that a great advantage rivets have over bolts: as you tighten a bolt, tension makes it thinner, so the space between the bolt and it's hole increases. A rivet is tightened by hammering it, so it completely fills in it's hole. So if it's loaded in shear, no movement until failure. So, as a general rule, rivets better in shear loading, bolts better in tension, lengthwise loading. I think rivets are no longer as common because of welding; replacing a series of stress points with a continuous connection. It would be interesting to compare different attachment systems in a high end modeling program, cycle them a few million times and see what fails.
@@EthanPerkins-qq9qh That's interesting instruction Ethan. Bolts do indeed become thinner when tightened . But rivets when driven home must also surely have an " elastic retraction" (that might equal the creation of gaps around a bolt? I know lead is especially good for its almost negligeable rebound..Hardly useful in a structure, but great on a roof.
It's the building moving more than the weight right
Taiwanese critical item constructed as designed, and working perfectly.
Super impressed with how Taiwan's buildings stood up, and even leaned over - without falling down.
Keep up the corruption free construction work Taiwan! Keep it up!
If one was standing there and knew what the movement of the damper signified, I’m thinking there would be quite a pucker factor involved.
I can't fathom the forces involved here. Even having been in an Earthquake it is still hard for me to wrap my head around the sheer amount of mass moving when it happens. All that ground, water, buildings, everything, all getting tossed around like nothing. If you have never been around an earthquake when they happen, they are a humbling experience. (Read that as this old man nearly poo'd himself when it happened)
What is it made out of
I visited and I still dont know how it works
I wonder how much heat is produced in those dampers through this event. That's is so much energy to dissipate.
The Engineering is excellent, it has many features, designed for momentum detection, gauge pressure, as well as protection of the base foundations for them not to tear apart. Balance of nature as yin yang is applied in its concept. QUI LAI TAIPEI, CHINA, H.K....AND its Sovereign Independent states of CHINA.
It's scary how the ball ia stagnant in relation to building sway
Those dampers must be super hot after this
Engineering at it's finest!
This is absolutely incredible 👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
This reminds me of the time a vehicle pulled out in front of me, I put my foot on the brakes and the car stopped!
Doing a LOT of work on that day! Beautiful engineering!
I love how they just built a building that can withstand an earthquake of this strength. Being inside, calmly watching the ball swing, it's like "LOL, good try, Earth. Try harder next time.".
this is outstanding engineering. Imagine being there to actually witness it.
The damper is doing its job - saving the building.
This is great! 👍 Love this ❤
It's doing just what it should do it's so beautiful to see such big tech keeping people safe.
The sphere weighs 660 tons if anyone was wondering.
It's hypnotic. "Don't worry, there is no earthquake. Enjoy the free social media content."
Is the damper swinging or the building?
The damper is stationary. The building is moving.
Both. The Ball swings and the Building swings, together they counteract each other, so the Building doesn't swing that much.
That's what's keeping everyone alive....
すごいちゃんと機能してる。
This is engineering genius!
If this was in China, we'd have a much shorter video of a ball falling. Probably followed by the building, itself.
I saw that in 2008 (iirc) just after the 101 opened and at the time it was the tallest building in the world. It's an amazing feat of engineering although i didn't see it move.
However, I experienced my only earthquake whilst sat in the bar of the Taipei Shangri-La hotel during that trip when I spotted the curtains swaying. It scared the crap out of me because my bed on the 18th floor (again iirc) faced a huge floor to ceiling window and I had visions of me being launched through the window in the bed during the night. I didn't sleep a wink 😬
Is this object heavy?
660ton
I wonder if they recorded it with this 7.4 earthquake that just happened?😅
Not having to hear french people saying all in canon (asynchrone) chorus "Ooolaaalaaa Olllallaaa" (repeat endlessly) is such A RELIEF !!!
Also worth mentioning that, it weights 660 tonnes.
