The design flaw that almost wiped out an NYC skyscraper

Slate:

When it was built in 1977, Citicorp Center was, at 59 stories, the seventh-tallest building in the world. You can pick it out of the New York City skyline by its 45 degree-angled top.

But it’s the base of the building that really makes the tower so unique. The bottom nine of its 59 stories are stilts.

This thing does not look sturdy. But it has to be sturdy. Otherwise they wouldn’t have built it this way.

Right?

I’ve been reading about this story for years and it’s a fascinating one of design, ethics and responsibility.
