Why don't skyscrapers just fall over?

Are skyscrapers built to last forever?

According to Bill Baker, the structural engineer behind the Burj Khalifa, the typical building is designed to withstand winds from a 700-year storm, while larger skyscrapers are designed to withstand events that occur just once every two millennia.

What is the weakest part of a skyscraper?

Remember how a corner is the strongest part of a building? Not this one. With the pillars on the edges, the V-shaped load distributors, and the light mass of the building, the corners are the weakest part of the building.

Why do skyscrapers skip the 13th floor?

It would take you a massive 20 seconds to fall from the top of the building to the ground. But that's not the limit – hypothetically we can go much taller.
