Structural System The Spiraling Y shaped was utilized shape the structural core of the Burj Khalifa. The Burj Khalifa tower is crowned with a 4,000 tonnes structural steel telescopic spire, which houses communications equipment. It consists of series high-strength reinforced concrete walls: a strong central core is connected to three building wings. The spire was constructed from inside the building and jacked to its full height of over 200 metres (700 feet) using a hydraulic pump. Wind Engineering Design The tower does not contain any structural transfers. Structural System Material The tower superstructure of Burj Khalifa is designed as an all reinforced concrete building with high performance concrete from the foundation level to level 156, and is topped with a structural steel braced frame from level 156 to the highest point of the tower. The Burj Khalifa’s lateral system is a buttressed core that is 606 meters in height. 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. Structural System The Spiraling Y shaped was utilized shape the structural core of the Burj Khalifa. L-box, V-Box and temperature. As it rises from a flat base, setbacks occur at each element in an upward spiraling pattern, reducing the tower’s mass as it reaches skyward. High performance concrete with high compressive strength The structural system employed for Burj Khalifa can be called as the Buttressed Core System. The spiraling “Y” shaped plan was used to reinforce the structural core of Burj Khalifa. Structural System In addition to its aesthetic and functional advantages, the spiralling “Y” shaped plan was utilized to shape the structural core of Burj Khalifa. Each raft pour occurred over at least a 24 hour period. Structural System Brief Description 2.1. Other names the building has commonly been known as, including former names, common informal names, local names, etc. Built of reinforced concrete and clad in glass, the tower is composed of three elements arranged around a central buttressed core. Phase 3: 6 Boreholes (two with pressure meter testing) with depths up to 60m. The central core has a higher resistance towards the torsional resistance. It was determined the maximum long-term settlement over time would be about a maximum of 80mm (3.1"). In addition to its aesthetic and functional advantages, the spiraling “Y” shaped plan was utilized to shape the structural core of Burj Khalifa. This system was introduced by Fazlur Rahman Khan while at the architectural firm Skidmore, Owings & Merrill (SOM), in their Chicago office. ... For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system… 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. This enabled construction to proceed without the normal delays associated with column transfers. The tower is composed of three elements arranged around a central core. 2 STRUCTURAL SYSTEM BRIEF DESCRIPTION 2.1 General The Burj Khalifa project is a multi-use development tower with a total floor area of 460,000 square meters that includes residential, hotel, commercial, office, entertainment, shopping, leisure, and parking facilities. d) 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 concrete was also designed as a fully self consolidating concrete, incorporating a viscosity modifying admixture with a slump flow of 675 +/- 75mm to limit the possibility of defects during construction. 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 chloride and sulfate concentrations found in the groundwater are even higher than the concentrations in sea water. Burj Khalifa is equivalent to 17 football (soccer) fields or 25 American football fields.
