Waving in the wind

Tried to wait a couple weeks before my next question, hope that is long enough.
How much does the Burj Khalifa sway in a good wind? An inch? A foot? A yard?

About two meters at the very top.

What angle would this make the floor tilt?

very, very little. it's mostly displacement, not rotation. concrete isn't very stretchy, but it can be designed to bend a bit.

Applying some basic trigonometry, assuming that the top floor at 584.5 m sways a maximum of 2 m (which I doubt since he said "at the top" which is 828 m but anyway...) you're talking an angle of .18 or eight hundredths of a degree.

If we're talking about the actual top moving that much, you're looking at only .13 degrees.
