The Tallest Structure

The tallest structure in the world is the "Burj Khalifa" located in Dubai. It stands 828m tall, and it took aproximately 5 years to complete. The tower gets slimmer as it increases in height which keeps it from falling over. The base is supported by a concrete mat 3.7 meters thick. Concrete in the base has to have a high density to support the structure's weight.

The "podium" area of this structure is used as the center of gravity. Most of the materials making up the structure are located in the center. The weight prevents the tower from tipping and making the height of the structure physically possible.Also, a Y shape makes up the core of the Burj to keep it stable and reduce wind forces. Coloumns are used to strengthen the walls and other mechanisms that help resist weights.
