**Earthquake Engineering Maths **

**Take 2:**

Structural Engineer Ron Klemencic explained on the Discover News that a simple rule of thumb for calculating skyscraper sway was to simply divide the buildings height in by 500 because the building codes demand the building fit a 1:500 sway ratio.

The tallest building in the world at 2,716 feet (828m), the Burj Khalifa, Dubai, would sway back and forth about 5.5 feet or 1.7 m.

**Ahhhhhhhhh! But you would have to drag Mathspig onto the 168th floor screaming.**

**But mathspigs you can work out the sway on the top ten tall buildings in the world.**
