Build big diagonal braces on the outside of the skyscraper
Great choice! Your building is stable enough to take on the Windy City!

Diagonals turn rectangles into triangles, and triangles are one of the strongest shapes used in construction today. In fact, the 12th tallest building in the world, the John Hancock Center in Chicago, has five sets of enormous diagonals on each of its four sides to keep from falling over in the wind.

This design, which essentially works like an immense hollow tube, greatly reduces the total weight of the building. The Empire State Building, 102 stories high, weighs 42.2 pounds per square foot. But the 100-story John Hancock Center, equipped with external diagonal braces weighs only 29.7 pounds per square foot! You've made the right choice. Your building is stable and light enough to take on the Windy City!
