In the example of Burj Khalifa (the Dubai skyscraper) the structure that is used is the bundled tube design. The concept of a tube system is to resist lateral loads by designing a hollow cantilever that is perpendicular to the ground. This allows minimal structure inside the space as it is pushed to the exterior walls. The method of tube design is developed through reinforced concrete in this case. Special mixes of concrete were used to withstand high pressures from the massive building weight. The site would ultimately determine the application of the concrete. The Persian Gulf temperatures would reach 122 degrees Fahrenheit during the day. Most of the concrete was poured at night when the air is cooler and the humidity is higher. The cooler concrete mix cures evenly with a lower rick in it cracking. A bundled tube design through concrete would be my interpretation of how this building is held up.
