"The Burj Khalifa Sways So Much You Can Feel It" — True or Total Myth ?

Then they discovered it wanted to shake itself apart. The Burj Khalifa was meant to be the ultimate triumph a $1.5 billion, 828-meter tower piercing the Dubai sky, the undisputed tallest structure ever raised by human hands. At near-kilometer heights, the engineers expected gravity to be their enemy. They were wrong. The real threat was invisible: high-velocity desert winds curling around the tower, spinning off violent whirlpools of air on either side a Kármán vortex street with the power to rock the entire building from side to side like an invisible hand. Then the terrifying part surfaced. If those swirling vortices ever locked onto the tower's natural rhythm, the resulting crosswind oscillations could sicken every occupant inside and threaten the structure itself. To survive, the architects had to "confuse the wind," twisting the geometry into a spiraling Y-shape with 27 stepped setbacks so no organized gust could ever take hold. And even now, the tower doesn't stand perfectly still its pinnacle is designed to sway up to two meters in a storm, while sensors track billions of data points a year on a slender steel spire that never stops quietly vibrating. This is how the world's tallest building became a multi-million-dollar math equation fighting the wind every second it stands. ─────────────────────────────
