concrete and blended with structural steel. This structural system enables the building to support itself laterally and keeps it from twisting. The two wings enclose space in center to form largest atrium in the world standing about 180m height. The “V” shape steel frame wraps around the reinforced concrete tower inhabiting hotel rooms and lobbies. By combining cutting-edge technologies and cultural influences, the building serves as a global icon that is both a model for future urban centers and speaks to the global movement towards compact, livable urban areas. This settlement would be a gradual curvature of the top of grade over the entire large site. Its reinforced concrete structure makes it stronger than steel-frame skyscrapers. Khan's contributions to the design of tall buildings have had a profound impact on architecture and engineering. 3.1 Lateral Load Resisting System. Local aggregates were utilized for the concrete mix design. SOM applied a rigorous geometry to the tower that aligned all of the common central core and column elements. Phase 2: 3 Boreholes drilled with cross-hole geophysics. Each wing, with its own high performance concrete corridor walls and perimeter columns, buttresses the others via a six-sided central core, or hexagonal hub. Similar to Burj Khalifa, as each wing is buttressed by the other two, therefore, the stability of the structure is greatly enhanced. 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, entertain-ment, shopping, leisure, and parking facilities. These include a “sky-sourced” ventilation system, in which cool, less humid air is drawn in through the top of the building. The Burj Khalifa (Arabic: برج خليفة, ; pronounced English: /ˈbɝdʒ_kə'li:fə/), known as the Burj Dubai prior to its inauguration in 2010, is a skyscraper in Dubai, United Arab Emirates. The Burj Khalifa’s lateral system is a buttressed core that is 606 meters in height. When the construction was at Level 135, the average foundation settlement was 30mm (1.2"). The building officially opened on 4 January 2010. In addition to its aesthetic and functional advantages, the spiraling “Y” shaped plan was utilized to shape the structural core of Burj Khalifa. 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. Burj Khalifa structural health monitoring Strainstall completed a monitoring contract on the tallest man-made structure ever built - the Burj Khalifa Tower in Dubai. This design helps to reduce the wind forces on the tower, as well as to keep the structure simple and foster constructability. 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 wind shears and moments. Burj Khalifa uses the bundled tube design of the Willis Tower, invented by Fazlur Rahman Khan. The spire was constructed from inside the building and jacked to its full height of over 200 metres using a hydraulic pump. 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 spire was constructed from inside the building and jacked to its full height of over 200 metres (700 feet) using a hydraulic pump. The tower does not contain any structural transfers. 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 solid reinforced concrete raft is 3.7 meters (12 ft) thick and was poured utilizing C50 (cube strength) self consolidating concrete (SCC). The exterior cladding of Burj Khalifa began in May 2007 and was completed in September 2009. The structural system employed for Burj Khalifa can be called as the Buttressed Core System. The advantage of the stepping and shaping is to "confuse the wind'1. 2. Reinforcement was typically at 300mm spacing in the raft, and arranged such that every 10lh bar in each direction was omitted, resulting in a series of "pour enhancement strips" throughout the raft at which 600 mm x 600 mm openings at regular intervals facilitated access and concrete placement. 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. The Dubai Municipality (DM) specifies Dubai as a UBC97 Zone 2a seismic region (with a seismic zone facior Z = 0.15 and soil profile Sc). To reduce the effects of differential column shortening, due to creep, between the perimeter columns and interior walls, the perimeter columns were sized such that the self-weight gravity stress on the perimeter columns matched the stress on the interior corridor walls. The spire of Burj Khalifa is composed of more than 4,000 tons of structural steel. The five (5) sets of outriggers, distributed up the building, tie all the vertical load carrying elements together, further ensuring uniform gravity stresses: hence, reducing differential creep movements. 18 | Validating the Dynamics of the Burj Khalifa CTBUH Journal | 2011 Issue II Structural Overview The Burj Khalifa Project is the tallest structure ever built by man (see Figure 1). 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. SOM created a simple Y-shaped plan to reduce wind forces, as well as to foster constructability. 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. Architecture. The advantage of the tower's stepping and shaping is, in essence, to “confuse the wind.” Wind vortexes can never sufficiently coalesce because the wind encounters a different building shape at each tier. heights periodically. The concrete mix for the piles was a 60 MPa mix based on a triple blend with 25% fly ash, 7% silica fume, and a water to cement ratio of 0.32. Burj Khalifa is equivalent to 17 football (soccer) fields or 25 American football fields. The Burj Khalifa’s lateral system is a buttressed core that is 606 meters in height. Other Names. Its 160 floors have a number of uses including residential units, office spaces and hotel rooms. 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. The site geotechnical investigation consisted of the following Phases: A detailed 3D foundation settlement analysis was carried out (by Hyder Consulting Ltd., UK) based on the results of the geotechnical investigation and the pile load test results.
