The Empire State Building does not sway, it gives. With a wind of 110 miles an hour, the Building gives 1.48 inches. Movement off center is never greater than one quarter inch, thus measurable movement is only one half inch, one quarter inch on either side.

Refer to 'resonance'. Buildings are designed to give during high wind velocities. When the resonant frequency of the building is matched, the building crumbles. (Read up on Old Tacoma Narrows bridge).
