I can just imagine all the people that said "Oh no! It's moving! It's going to break!" when movement is the reason it's there. I'd be a lot more on edge if the 90th floor started to tremble and that thing didn't move.
The thing is, it's a massive 800 ton object moving back and forth like an egg in the fridge. The sheer scale of that object moving like that is unnerving... it means the energy involved is absolutely massive, which of course we know it is. The entire building is moving which is even more massive, and the entire land mass below it is moving, which is even more massive.
@@The_Real_Slim_Shadow94 dude you think your cool, this is Erie. The thought of 700 tons swinging over your heads at anytime your in that tower would give me goosebumps
"so as not to collapse" this is incorrect, the building would never collapse, but the mass damper makes the top floors more comfortable for high level personnel.
shawn means the building is strong enough to handle high winds and rough earthquakes on it's own, the damped pendulum is more there for guest comfort than for structural stability. he is correct.
Basically anything strong enough to destroy the building without the tuned damper will still destroy the building with the tuned damper. It's tuned to the building's resonance at rest, not when being acted upon by an earthquake.
I always wondered what would happen if the cables that held that damper failed. Would the sphere have enough weight to punch through to the foundation.
The ball moves at a frequency that differs from the building's natural frequency, so the energy is spread out, reducing the peak movement to a safe level. So, yes, the ball moves. See: en.wikipedia.org/wiki/Tuned_mass_damper#Principle
It's hard to know because we can't tell exactly how far it's moving. But my best guess is that it's accelerating at 0.7m per second at its fastest point. So that's 560,000 newtons, which is 560,000 joules of energy for every metre it moves. So for every metre it moves at top speed it could produce 56 kilowatts for one second
It's -stories -47 to -391, down in the basement. It acts as something that make the top of the building move a lot so there is little stress on the beams at the upper levels.
Jack C clearly not as i can understand his question and you babble on to try prove your intelligence online. Point proven, next time keep your fingers off the keyboard snd you wont get destroyed lol.
Hello, I'm a producer for AccuWeather. I'm doing a news package on the Taipei 101. Did you record this? If so, may we use this video for our syndicated news coverage? We will credit you.
My best guess is that the heavy 'ball' puts additional stress on the structure, comprising the tower's ultimate strength. For every action, there is an equal and opposite reaction. Perhaps they should just use more steel.
Myrkur the damper moves too. The first movement is jist the building, but after that most of the movement is the damper moving opposite the building. The shocks on the bottom drag it along so it absorbs some of the energy from the buildings movement.
TW is not a part of China because TW is China, it's complicate for people who don't understand the history and constitution of modern China... Countries in the world basically separate into two groups, one side recognized ROC to represent China, the others recognized PRC though...
TW is not a part of China, but PRC is also not part of Taiwan; Taiwan and China are both separate countries. And both nations are recognized. China wants to claim Taiwan as its own and pressure other countries to do so, because the existence of Taiwan is humiliating for China. However, under the perspective of the international community. Taiwan is actually an actual nation with passports, government, politics, international recognition, millitary, and many other things as requirements of a nation. China already have 0 control over Taiwan. In fact, in 1949 US had already granted ROC full control of the territory of Taiwan. Taiwan is also one of the largest economies in Asia, right behind South Korea.
Obviously, you know nothing about history of China at all.... 1. ROC and PRC both claimed that they are the rightful gov of China (not just PRC, you can go read the constitutions of both sides). 2. They both have 0 control over each other because of civil war in China. 3. USA or any other countries don't have the right to interfere other countries' internal affairs (you may go read the treaties between USA and PRC also USA and ROC)
You must still be sleeping in your dream mate, asia largest economies behind south korea? You are already about to be surpass by the South East Asia (Singapore), and even Malaysia has surpass you in-term of cities GDP, and it wont take too long before Thailand and Indonesia beat taiwan. And please, your economy are heavily relying on China. And why would a self-claimed independent nation needs to get recognition by the U.S.
This probably was moving due to wind and tall buildings more often need wind dampers. The Chinese National government went to Taiwan when the PRC 'revolution' dominated and in 1971 PRC -people's republic of China got UN recognition. Since then the PRC has been trying to get rid of Taiwan R.O.C. but the U.S. and others helped resist that or delay it, in less than "official" ways. The Nationalists are not communists, there may be a racial issue in the mix as well but it is mostly a difference in types of government that is at issue. Now a Democratic Constitutional Republic with 'unversal sufferage", private property rights verses what was supposed to be a communist revolution of the PRC but, like the old USSR there's been a lot of commercialism/capitalism creep in.
The Republic of China participates in most international forums and organizations under the name "Chinese Taipei" due to diplomatic pressure from the PRC
how do you know that? were you there? only those that were there knows the truth. you listen to fake information, because thats all you see. Be there, or be square.
I can read as can you, about wind dampening methods for countering sway of modern tall buildings. I said probably because there's a average of about 80 days a year where winds give people motion sickness to where they cannot work in tall buildings that do not remedy wind sway.
***** did you just call me a bitch? is this you singing? You got alot of nerve girl. Don't be calling others name's ok. You don't know me. You need to apologize for calling me that. You will never succeed with your music, with an attitude like that. respect others, I say, and it will come back to you.
Hi! I'm writing from Arrow Media International, a UK Production Company. We'd potentially be interested in showing this footage in one of our programs. You can reach me at freddie.warshaw@arrowmedia.com for more details. thanks!
Taipei 101 is a stupid design this ball, too conservative thinking, this ball = the building load, it need additional support for this ball, i don't think this is a good design, less experience. he who design this is a too theoretical learning from the book.
And what did you study (not from a book) that qualifies you to make this judgement? Do you really believe that inexperienced engineers, fresh out of school, design tuned-mass dampers for large buildings? Would you trust a designer who had never studied dynamics (from a book, alas) to do it properly using hunches and guesswork?
The principle design of the steel ball is design to anti-wind load, sir, but this ball is also equal to the building's weight, think about it , I want to anti-wind load , but I add a structure which is and additional think equal to the build ,we all know that if you add the loading to the building (I mean this steel ball), the structure must design stronger and stronger and stronger structure to support this fuck-up steel ball , this way really really really waste money and no econmic , actually, there are a lot a way to substitute the ball so that the building can anti-wing load.

Cool. When does it hatch?
That is so cool. Human ingenuity is so inspiring...
No!🤬

Yeah, also the holders are made out of ropes and it managed to survive. Maybe they were flexibe enough.

Salute to the engineers behind Taipei 101
That's so amazing and eerie.
You sound like the kind of person who thinks the lever and the wheel are eerie
@@The_Real_Slim_Shadow94 dude you think your cool, this is Erie. The thought of 700 tons swinging over your heads at anytime your in that tower would give me goosebumps
@@osomnm431 how the fuck do you make the connection between 'disagreeing with you' and 'thinking I’m so cool'? Such a sensitive prick.
Ok, I knew it moved, I knew this video would show it moving. I did not know, HOW MUCH it would actually move. Holy shit.
Yeah it’s odd to see over 700 tons swinging toward you at that speed
@@dongatello6969Under 700 tons, 660 to be exact. But yes, it's impressive.
0:02 Mass Dumper? yeah watch out for the big turds falling.
Oh shit (literally)
Big Dumper they call it
so fucking clever wow
That joke made me shit me pants
But will it blend?
Probably
Ham94 how big is your blender?
that is the question
GMM
"so as not to collapse"
this is incorrect, the building would never collapse, but the mass damper makes the top floors more comfortable for high level personnel.
If the oscillation is too great what do you think will happen ? It dampens the oscillations so yes it prevents collapse.
shawn means the building is strong enough to handle high winds and rough earthquakes on it's own, the damped pendulum is more there for guest comfort than for structural stability. he is correct.
Basically anything strong enough to destroy the building without the tuned damper will still destroy the building with the tuned damper. It's tuned to the building's resonance at rest, not when being acted upon by an earthquake.
precisely
The resonant frequency of the building at rest is the same as the resonant frequency of the building while it oscillates.
This is so interesting to me, thanks for posting/sharing the video.
Does the dampener move or is it the building moving, and the dampener is in a fixed position.
Probably silly question but im curious
I think it’s a little bit of both
The dampener oscillates in a way that counteracts the building's oscillation. So both are moving.
Both moves, but the use of Damper is to absorb the loads from earthquake and strong winds so that the building will not move much
I always wondered what would happen if the cables that held that damper failed. Would the sphere have enough weight to punch through to the foundation.
The ropes are strong enough and probably they first test it before they make an another one
The ropes are built to withstand forces and mass exceeding the weight of the dampener.
Chances of more then one cable failing at the same time are very low
I like how no one answered the question and instead made up their own question to answer... They all are different questions too...
Tristhal Haha, ok then.
Chris Quetsch Depends on how thick the foundation is, but I'd guess probably not. Might make a pretty good crater though.
the ball is not moving. the building is. the ball is just absorbing some of that energy. thanks grady from Practical engineering!
The ball is moving. I've watched the video and don't know where it talks about the ball not moving?
the ball moves thats the half of the point.
The ball moves at a frequency that differs from the building's natural frequency, so the energy is spread out, reducing the peak movement to a safe level. So, yes, the ball moves. See: en.wikipedia.org/wiki/Tuned_mass_damper#Principle
Wow dude i just watched the same vid and came here to see this after...recorded knowledge spreads far..im in the fkin bahamas
Both ball and building move in opposition to each other, damping out the amplitude of building sway.
How much energy does a 800 tone ball needs to move like that, how much it has consumed?
Let's calculate
It's hard to know because we can't tell exactly how far it's moving. But my best guess is that it's accelerating at 0.7m per second at its fastest point. So that's 560,000 newtons, which is 560,000 joules of energy for every metre it moves. So for every metre it moves at top speed it could produce 56 kilowatts for one second
Camera should have to be stable...

Which floor can you see it from?
***** I've read the Wiki and experience, that everyone can see the pendulum between floor 88 and 92.
It's -stories -47 to -391, down in the basement. It acts as something that make the top of the building move a lot so there is little stress on the beams at the upper levels.

Hello, producer for AccuWeather, did you use this?
Go ahead and use it they told me it's ok
One day, we will reach the stars.
Or die trying
Are you from singapore?
Is this high in building or low?
High. Between the 87th and 89th floors
stunning
What happens if the things holding it up breaks and this things falls?
It would fall and collapse the floors and then collapse the entire building
what will happen if the damper fail
whyle moving?
How were they able to put this up there ?
I believe they built up there it layer by layer instead of building the whole thing together before transporting it up. Kinda an “IKEA” approach to it
Thats my 800 ton balls, i have 2 of them to damp my reciprocating motion
hol´ up
Yes it is.
Is the TMD moving or the building?!?
frank2398 both
That buildings got a massive dumper
Mass dumper?
that was during a typhoon not an earthquake...if youre going to steal a video get it right
that's just incredible. the courses of physics seem to be true!
The engineer in me wants to a mass damper move in person
I wish i could see the damper swaying
Nice video, thanks for uploading!
But Taiwan is not a province in China.
Hoping you will correct it. : )
660 Ton mass
I swear when one day the earthquake is so strong that whole building is gonna fall
My best guess is that the heavy 'ball' puts additional stress on the structure, comprising the tower's ultimate strength. For every action, there is an equal and opposite reaction. Perhaps they should just use more steel.
It keeps the tower from reaching it's resonant frenquency so it dosent crack every Thing in the building and Also provide stability
The dampaner is not moving the building is
Myrkur the damper moves too. The first movement is jist the building, but after that most of the movement is the damper moving opposite the building. The shocks on the bottom drag it along so it absorbs some of the energy from the buildings movement.

it looks like the insides of the enterprise
How lucky to have been there the same time of the earthquake
The dude who took this video needs to have any filming devices immediately confiscated.
I would get the fuck out of there that’s for sure that bal itself even creeps me out
kind of terrifying
