There are also a few perimeter columns supporting flat plates at the ends, Fig.2. These walls behave like the web and flanges of a beam to resist the wind shears and moments. The corridor walls extend from the central core up to the end of wing, where they have thickened with hammer head walls. This central core provides the torsional resistance for the structure similar to a closed pipe or axle (Ref.5,6). This shape along with the upward spiraling pattern of setbacks in the wings, helped to reduce the wind forces on the tower (the shape was determined based on extensive wind tunnel tests). The structural system can be described as a “buttressed core”, and consists of high performance concrete (HPC) wall construction. Each of the wings buttresses the others via a hexagonal central core, Fig. The “Y” shaped floor plan provides high-performance and maximizes views of the Persian Gulf. 3).įigure 3: Comparision of height of other well-known structures (Source: Ref. The design is based on the 73-floor Tower Palace Three, an all-residential building in Seoul, South Korea (Ref. The Burj Dubai resembles the bundled tube form of the Willis Tower, but is not a tube structure. The architectural and structural design for the Burj Dubai was performed by Adrian Smith and his team of ninety designers at the Chicago office of Skidmore, Owings and Merrill (SOM). (Adrian Smith worked with the company till 2006.) SOM also designed the Willis Tower (formerly known as Sears Tower) in Chicago, Illinois and 1 World Trade Center in New York City. Taken 22 million man-hours to construct.The total weight of aluminium used on Burj Dubai is equivalent to that of five A380 aircraft and the total length of stainless steel bull nose fins is 293 times the height of Eiffel Tower in Paris.Curtain walls: 83,600 sq.m of glass and 27,900 sq.m of metal (equivalent of 17 soccer fields).Steel rebars: 39,000 tonnes (laid end to end this would extend over a quarter of the way around the world).Total area: Tower+ Podium: 465,000 sq.m area ¨ Concrete used : 250,000 cu.m (weight of 110,000 elephants).Area of Tower: 280,000 sq.m residential and office space and a Giorgio Armani hotel.The height and the number of stories were kept as a secret till the opening of the tower. The total project cost is estimated to be around US$20 billion, out of which the tower itself will cost $4.2 billion. In addition the Giorgio Armani hotel is also situated in this tower (will occupy the first 37 floors). The tower has 280,000 m 2 of area which will be utilized predominantly for 700 residential apartments in floors 45 through 108, and corporate offices, in the remaining space up to the 160 th floor. The Burj Dubai project located near down-town Dubai, United Arab Emirates, consists of the following:
