The Burj Khalifa through Virtual Reality



About burj khalifa

 central core emerges at the top and culminates in a sculpted spire. A Y-shaped floor plan maximizes views of the Arabian Gulf. Viewed from the base or the air, Burj Khalifa is evocative of the onion domes prevalent in Islamic architecture.




Wind Tunnel Testing


Over 40 wind tunnel tests were conducted on Burj Khalifa to examine the effects the wind would have on the tower and its occupants. These ranged from initial tests to verify the wind climate of Dubai, to large structural analysis models and facade pressure tests, to micro-climate analysis of the effects at terraces and around the tower base. Even the temporary conditions during the construction stage were tested with the tower cranes on the tower to ensure safety at all times.



Stack effect or chimney effect is a phenomenon that affects super-tall building design and arises from the changes in pressure and temperature with height. Special studies were carried on Burj Khalifa to determine the magnitude of the changes that would have to be dealt with in the building design.



Construction


Excavation work began for Burj Khalifa in January 2004 and over the ensuing years to its completion; the building passed many important milestones on its goal to become the tallest man-made structure the world has ever seen. In just 1,325 days since excavation work started in January 2004, Burj Khalifa became the tallest free-standing structure in the world.



Construction Highlights


Over 45,000 m3 (58,900 cu yd) of concrete, weighing more than 110,000 tonnes were used to construct the concrete and steel foundation, which features 192 piles buried more than 50 m (164 ft) deep. Burj Khalifa's construction will have used 330,000 m3 (431,600 cu yd) of concrete and 39,000 tonnes (43,000 ST; 38,000 LT) of steel rebar, and construction will have taken 22 million man-hours.



The exterior cladding of Burj Khalifa began in May 2007 and was completed in September 2009. The vast project involved more than 380 skilled engineers and on-site technicians. At the initial stage of installation, the team progressed at the rate of about 20 to 30 panels per day and eventually achieved as many as 175 panels per day.



The tower accomplished a world record for the highest installation of an aluminium and glass façade with a height of 512 metres. The total weight of aluminium used on Burj Khalifa is equivalent to that of five A380 aircrafts and the total length of stainless steel bull nose fins is 293 times the height of Eiffel Tower in Paris.



In November 2007, the highest reinforced concrete core walls were pumped using 80 MPa concrete from ground level. A vertical height of 601 metres. This smashed the previous pumping record on a building of 470m on Taipei 101; the world’s second tallest tower and the previous world record for vertical pumping of 532 metres for an extension to the Riva del Garda Hydroelectric Power Plant in 1994. The concrete pressure during pumping to this level was nearly 200 bars.



The amount of rebar used for the tower is 31,400 metric tons - laid end to end this would extend over a quarter of the way around the world.
