The superstructure is currently under construction and as of fall 2020 has reached over 160 stories. The final height of the building is 2,717 feet (828 meters). The height of the multiuse skyscraper will fortably exceed the current record holder, the 509 meter (1671 ft) tall Taipei 101. The 280,000 m2 (3,000,000 ft2) reinforced concrete multiuse Burj Dubai tower is utilized for retail, a Giorgio Armani Hotel, residential and office. As with all supertall projects, difficult structural engineering problems needed to be addressed and resolved。 Structural System Description Burj Khalifa has refuge floors at 25 to 30 story intervals that are more fire resistant and have separate air supplies in case of emergency. Its reinforced concrete structure makes it stronger than steelframe skyscrapers Designers purposely shaped the structural concrete Burj Dubai Y shaped in plan to reduce the wind forces on the tower, as well as to keep the structure simple and foster constructibility. The structural system can be described as a buttressed core (Figures 1, 2 and 3). Each wing, with its own high performance concrete corridor walls and perimeter columns, buttresses the others via a sixsided central core, or hexagonal hub. The result is a tower that is extremely stiff laterally and torsionally. SOM applied a rigorous geometry to the tower that aligned all the mon central core, wall, and column elements。 Each tier of the building sets back in a spiral stepping pattern up the building. The setbacks are organized with the Tower39。s grid, such that the building stepping is acplished by aligning columns above with walls below to provide a smooth load path. This allows the construction to proceed without the normal difficulties associated with column transfers The setbacks are organized such that the Tower39。s width changes at each setback. The advantage of the stepping and shaping is to confuse the wind39。1. The wind vortices never get organized because at each new tier the wind encounters a different building shape. The Tower and Podium structures are currently under construction (Figure 3) and the project is scheduled for topping out in 2020。 Architectural Design The context of the Burj Dubai being located in the city of Dubai, UAE, drove the inspiration for the building form to incorporate cultural, historical, and organic influences particular to the region。 The center hexagonal reinforced concrete core walls provide the torsional resistance of the structure similar to a closed tube or axle. The center hexagonal walls are buttressed by the wing walls and hammer head walls which behave as the webs and flanges of a beam to resist the win
