Keeping Skyscrapers From Blowing in the Wind

Fueled by a scarcity of land and by demand from multimillionaires willing to pay record prices for helicopter views of Central Park and beyond, Manhattan developers are building ever taller, ever thinner apartment buildings on ever tinier lots. Clustered mostly in and around West 57th Street, these skinny skyscrapers are reaching heights of more than 1,000 feet.

One consequence of beanstalk proportions: The higher and slimmer buildings get, the more they tend to sway at the top.
