It’s always so crazy being this close and looking up. You can literally see it swaying.
Edit: I was a lot younger when I last visited and I swear I remember seeing it sway a little lol but maybe it was my brain playing tricks on me. Googling around and I do see others claim to see or feel the sway.
I’ve never noticed and I’ve stood there several times.
I've also never noticed it swaying.
I bet most tall towers sway a bit, and are designed to do so. Though from the top, I couldn't feel it swaying.
I doubt a photo would be able to capture the level of sway that happens. The effect I captured in the photo I think is due to the subtle concave angle of the sides, accentuated by the angle of the photo.
I looked up about the give buildings like this have and it isn’t much. 1-3 feet at the very top. I doubt it’s perceptible but I don’t doubt your brain tricks you into seeing it seem as though it is swaying
I’ve not been to this tower, but the whole skyscraper-swaying thing totally weirded me out when I first learned about it. It all seemed so counterintuitive at first, but the fact these things are actually engineered to sway to withstand the wind loads on them is nothing short of remarkable.
Just think about it - the entire design, the architecture, the engineering, the columns, the floor plates, expansion joints (I presume), etc. are all designed to sway within a certain tolerance. These towers are so normal to see in our cities, but they really are hallmarks of human achievement.
