Ah, memories -- in my case mostly of all-night Civ games in Publications

Structural Integrity | 99% Invisible
'The student (who has since been lost to history) was studying Citicorp Center as part of his thesis and had found that the building was particularly vulnerable to quartering winds (winds that strike the building at its corners). Normally, buildings are strongest at their corners, and it’s the perpendicular winds (winds that strike the building at its face) that cause the greatest strain. But this was not a normal building.

LeMessurier had accounted for the perpendicular winds, but not the quartering winds. He checked the math, and found that the student was right. He compared what velocity winds the building could withstand with weather data, and found that a storm strong enough to topple Citicorp Center hits New York City every 55 years. But that’s only if the tuned mass damper, which keeps the building stable, is running. LeMessurier realized that a major storm could cause a blackout and render the tuned mass damper inoperable. Without the tuned mass damper, LeMessurier calculated that a storm powerful enough to take out the building his New York every sixteen years.'
