Dieses Hochhaus in Chicago (150 North Riverside) hat ein Fundament, das schmäler ist (!) als das Gebäude selbst und oben drauf einen Wassertank. Warum fällt so ein Gebäude aber nicht einfach um?
“You might think that this would make the entire building structurally unstable — and you’d be right, if this feature wasn’t compensated for in the design and construction process.” The engineering involves making the arms of the Y‑shaped lower levels “entirely out of steel. These elements precariously spring out of the concrete core and transfer all of the loads of the outside floors above. The forces are so great, these steel members are the largest I‑beams ever made,” specially designed and manufactured for this project. […] On the other end sits a “tuned mass damper, which, fundamentally, is just a giant concrete water tank at the top of the building.” When wind blows against the tower, causing it to bend slightly, the water sloshes around in response. “But the water moves slower than the building does, so its weight is back over the original center of gravity,” which keeps the structure from bending too far.

Meine Güte, Architekten, Ingenieure, vor allem aber Statiker oder wer auch sonst an sowas beteiligt ist, was macht ihr mit meinem Kopf?! Wasser oben, schmales Fundament unten… Ich definiere euren Job nunmehr mit dem Slogan: Wo sich Angst und Faszination treffen!
