Burj Khalifa (Arabic: , "Khalifa Tower") is an extremely tall skyscraper in Dubai, United Arab Emirates named after Khalifa bin Zayed Al Nahyan, and is the tallest building ever built, at 828 metres (2,717 feet).Before the building opened, it was called Burj Dubai.The building is 162 stories high. The raft was constructed in four (4) separate pours (three wings and the center core). 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. Each raft pour occurred over at least a 24 hour period. Burj Khalifa structural health monitoring Strainstall completed a monitoring contract on the tallest man-made structure ever built - the Burj Khalifa Tower in Dubai. The building was earlier known as Burj Dubai but was renamed in honor of the ruler of Abu Dhabi and the president of the UAE, Khalifa Bin Zayed Al Nahyan. 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. Seismic loading did govern the design of the reinforced concrete Podium buildings and the Tower structural steel spire. This design helps to reduce the wind forces on the tower as well as keep the structure simple and constructability. The Burj Khalifa tower is crowned with a 4,000 tonnes structural steel telescopic spire, which houses communications equipment. Burj One dificulty faced in the design of this marvelous structure was the structural aspect. Its reinforced concrete structure makes it stronger than steel-frame skyscrapers. Construction began on 21 September 2004, with the exterior of the structure completed on 1 October 2009. 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. At 828 metres (2,717ft) tall, the tower has 160 floors comprising hotels, restaurants, luxury residences, offices, and the worlds highest swimming pool and outside observation deck. The second mode is a perpendicular lateral side sway with a period of 10.2 seconds. Photo of the Completed Burj Khalifa The structure of Burj Khalifa was designed to behave like a giant column with cross sectional shape that is a reflection of the building massing and profile. It consists of series high-strength reinforced concrete walls: a strong central core is connected to three building wings. Khalifa is designed as an all + 585.7m 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 280,000-square-meter skyscraper contains office, residential, and retail space, along with a Giorgio Armani hotel. The curtain wall of Burj Khalifa is equivalent to 17 football (soccer) fields or 25 American football fields. The structure of Burj Khalifa was designed to behave like a giant column with cross sectional shape that is a reflection of the building massing and profile. The dynamic analysis indicated the first mode is lateral side sway with a period of 11.3 seconds (Figure 7). 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. https://civilengineeringupdates.blogspot.com/2013/05/1.html The spiraling Y shaped plan was used to reinforce the structural core of Burj Khalifa. 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. The story of structural system selection and the structural system optimization is a 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 groundwater in which the Burj Dubai substructure is constructed is particularly severe, with chloride concentrations of up to 4.5%, and sulfates of up to 0.6%. 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 decision to build Burj Khalifa was based on the governments decision to diversify from an oil-based 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. Burj Khalifa is the first mega-high rise in which certain elevators are programmed to permit controlled This design helps to reduce the wind forces on the The whole system is constructed by using high performance concrete wall. The C60 (cube strength) SCC concrete was placed by the tremie method utilizing polymer slurry. Each wing buttresses the other through a hexagonal central core as shown in figure-2. When the construction was at Level 135, the average foundation settlement was 30mm (1.2"). Similar to Burj Khalifa, as each wing is buttressed by the other two, therefore, the stability of the structure is greatly enhanced. Burj Khalifa is equivalent to 17 football (soccer) fields or 25 American football fields. Each wing is also braced by a series of buttress walls which are connected by coupling beams and radiated from a central closed prismatic tube. 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. Burj Khalifa - Major Structural System It is correct to say that nowadays the Burj Khalifa represents the concept of excellence in building design. 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. Keywords: architectural forms, Burj Khalifa, structural components, dynamic wind effects. Adrian Smith is the man for the structural and architectural design of Burj Khalifa. 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. The RWDI wind engineering was peer reviewed by Dr. Nick Isyumov of the University of Western Ontario Boundary Layer Wind Tunnel Laboratory. Burj Khalifa uses the bundled tube design of the Willis Tower, invented by Fazlur Rahman Khan. The setbacks are organized such that the Tower's width changes at each setback. The architecture features a triple-lobed footprint, an abstraction of the Hymenocallis flower. The advantage of the stepping and shaping is to "confuse the wind'1. The final height of the building is 2,717 feet (828 meters).
