Burj Khalifa, which stands at 828 meters in Dubai, United Arab Emirates, is the tallest building in the world as of 2017. Designed by SOM, the Burj Khalifa is a mega-building that is resistant to extreme desert climate conditions, formed by a combination of traditional Arab culture and the most modern technological developments.
Burj Khalifa is a multi-functional building with various functions such as commercial, office, residential and hotel. The building’s Y-shaped plan layout allows views of the Persian Gulf and Dubai to be seen from each floor. At the same time, this plan plane is a factor that helps the structure to be structurally durable. Each wing of the Y-shaped structure has its own reinforced concrete core and bearing columns. Each wing is supported by both its own carrier system and a hexagonal central core. Thus, a skyscraper emerges that is very resistant to bending force. The building is surrounded by green areas on the Yesil floor, water pools and walkways where visual shows are held.
Skidmore, Owings & Merill took traditional Islamic architecture and the geometric shape of local desert flowers into consideration when designing the Burj Khalifa. The huge 828-meter-high structure stands with reinforced concrete carriers. Volumes of different heights, which give the structure its overall shape, rise around the core located in the center of the plan plane. The structure rises spirally from a flat floor, and as it rises upwards, pieces of mass that rise at certain elevations decrease. Thus, the overall mass of the structure decreases as it rises upwards. At the climax of the structure, the core in the center turns into a pointed Tower cone.
As the structure rises, the mass declines are designed in accordance with the grid system of the Burj Khalifa. Each reduction reduces the width of the building. At the level where each step is located, the columns rising up were equaled under the curtain walls, thus preventing problems that may occur during the transition between the columns. This upward lightening shape of the skyscraper makes the structure resistant to wind load. Wind loads hit a different shape at each elevation of the structure, so the wind “gets confused.”
