This is how this Tuned Mass Damper controls vibration on buildings.

Tuned Mass Damper. Little known and INCREDIBLY important device

[@Innotutorial]

For real

[@nuschlerclark895]

I’m reading an in depth analysis of the Citicorps building in NYC. A massive error of bad engineering design by an egotistical builder who was mainly concerned with how a structure looked rather than just building a sound design. I have greater respect for mechanical engineers after watching your video! Thank you!!

The classic example used in engineering videos is the Tuned Mass Damper in the Taipei 101 building. It is made of steel and weighs 730 tons. It was hoisted up in pieces to the top of the building by a construction crane, and the sections were welded together to form a single mass. There is video online of the damper in action during a 6.8 magnitude earthquake. The damper is swaying with a frequency of about 7 seconds, and reverses direction a few inches short of the travel limit stops. After about 30-40 seconds the earthquake passes by, the building returns to vertical and the mass damper stops moving.

Great video, many thanks!

[@Innotutorial]

@anthonymorris1360 you welcome dear

[@vetteltuna1716]

If the damper was only supported by a single point, wouldn't it still enable for the centre of mass to remain in the middle? or am i missing something

[@Innotutorial]

That will be a different study

[@emnadebbech3791]

cool video, But I have a question : How did you do the experience at the end of the video what did you use for the TMD ? (I got that the tower is made of some sheet of paper)

[@Innotutorial]

Thank you for the comment. These were simply experiments done with the use of cardboard to show how tuned mass dampers could be effective in damping the vibration of structures. The second was without any lateral resisting element(bare frame). The third was a normal brace frame which provide some lateral stiffness. While the first was with a tuned mass. This provided more lateral stiffness.
