The Taipei 101, once the world's tallest building, sits a paltry 600 feet from a fault line. So is the structure doomed? Nope -- it's rocking a uni-ball of steel.
To counteract the forces working against it, architects installed a $4 million, 730-ton tune massed damper, which is a big ball 18 feet in diameter, made of 41 steel plates, and suspended by strong cables 3 1/2-inches think. It's said to cut down on the swaying of the building by almost 40%.
Pretty cool stuff there. Anything that keeps buildings standing and people safe during an earthquake is A-okay in my book. Even if it is a 730-ton ball. Which, incidentally, explains why I've never taken a fall. *wink* Ladies?
