Twenty-six helical levels decrease the cross-section of the tower incrementa… The structural integrity of the building itself is the damping system. Structural System In addition to its aesthetic and functional advantages, the spiraling “Y” shaped plan was utilized to shape the structural core of Burj Khalifa. The setbacks are organized in conjunction with the tower’s grid: the stepping is achieved by aligning columns above with walls below to provide a smooth load path. Excavation work began for Burj Khalifa the tallest skyscraper in the world in January 2004 and over the years, the building passed many important milestones to become the tallest man-made structure the world has ever seen. Its reinforced concrete structure makes it stronger than steel-frame skyscrapers. Burj Khalifa is equivalent to 17 football (soccer) fields or 25 American football fields. Structural System Brief Description 2.1. Seismic loading typically did not govern the design of the reinforced concrete Tower structure. Construction of the tower was started in 2004. The geo-technical studies were peer reviewed by both Mr. Clyde Baker of STS Consultants, Ltd. (Chicago, IL, USA) and by Dr. Harry Poulos of Coffey Geosciences (Sydney, Australia). The structural system can be described as a "buttressed" core (Figures 1, 2 and 3). The tower does not contain any structural transfers. In structural engineering, the tube is a system where, to resist lateral loads (wind, seismic, impact), a building is designed to act like a hollow cylinder, cantilevered perpendicular to the ground. The spire of Burj Khalifa is composed of more than 4,000 tons of structural steel. In order to rise to the great heights, a proper structural support is necessary. The Burj Khalifa Project is the tallest structure ever built by man; the tower is 828 meters tall and compromise of 162 floors above grade and 3 basement levels. Ontario (Figure 14). After getting information directly of the website about the construction of Burj Khalifa, we were able to understand more about the structural system within the building. This system was introduced by Fazlur Rahman Khan while at the architectural firm Skidmore, Owings & Merrill (SOM), in their Chicago office. Dr. Max Irvine (with Structural Mechanics & Dynamics Consulting Engineers located in Sydney Australia) developed site specific seismic reports for the project including a seismic hazard analysis. The “Y” shaped plan also provided a stable platform on which to base the development of a new “buttressed core” structural system specially developed to support a building of this height while maintaining the tower’s slender and elegant shape. Keywords: architectural forms, Burj Khalifa, structural components, dynamic wind effects. The spire was constructed from inside the building and jacked to its full height of over 200 metres using a hydraulic pump. The curtain wall of Burj Khalifa is equivalent to 17 football (soccer) fields or 25 American football fields.

The 280,000 m2 (3,000,000 ft2) reinforced concrete multi-use Burj Dubai tower is utilized for retail, a Giorgio Armani Hotel, residential and office. It consists of series high-strength reinforced concrete walls: a strong central core is connected to three building wings. Local aggregates were utilized for the concrete mix design. Burj al Arab is made up of 28 storeys of split levels (56 Khan's contributions to the design of tall buildings have had a profound impact on architecture and engineering.
