Due to its flexible suspension and inertia, it follows the rest of the building with a delay just long enough to balance out shaking due to earthquakes. Basically the weight and the building swing against each other, canceling out strong motions in one direction.

That 'ball' is called a 'tuned mass damper': http://en.wikipedia.org/wiki/Tuned_mass_damper

A video of it in action: http://www.youtube.com/watch?v=NYSgd1XSZXc

Note: this isn't build for the Burj Dubai, it was proposed to build something like that inside, but rejected.

this building is incredible, its height and shape parameters breaks in the world, the most impressive is that according commented buildings have been even bigger in the future.

a greeting from Mexico.

هذا المبنى لا يصدق ، الى ذروته في تشكيل معالم والراحة في العالم ، أكثر وفقا للإعجاب هو ان المباني قد علق حتى اكبر في المستقبل.

تحية من المكسيك.

Anybody else think the tiers look empty? Is it just a flat roof on each tier, or something to make it a little more ornate?

I wonder if they'll put a small sign or something on the two top cranes (in the cab maybe?) when they are taken down to show that they were used on the worlds tallest building at heights never seen before. It would be nice for both of those cranes to be recognized for what they have done.
