Burj Khalifa in interesting number Burj Dubai Vs. some other buildings in the world Challenges video definition :: definition : Burj khalifa is a skyscraper located in the Emirate of Dubai, United Arab Emirates, The Burj khalifa the highest building built by man and the world's tallest tower. PowerPoint Presentation: definition : In year 2004 Began construction in the Emirate of Dubai, the completion of the restructuring of State in year 2009 , was officially opened in year 2010 , to become the world's tallest building immediately replace Taipei 101 in Taiwan. Why this name was called: : Why this name was called: During the opening of the tower, Sheikh Mohammed bin Rashid Al Maktoum , President of the UAE and Dubai, decide to change the name of the tower"Burj Dubai", to the Tower of Sheikh Khalifa bin Zayed Al Nahyan (President) to appreciation his efforts, and for his support of Dubai and all other Emarites . The Construction :: The Construction : Work began in January 2004 and amounted to a total cost of $ 1.5 billion The length of the tower 828 meters, a total area of 4,000,000 square meters Contain 37 floors and 403 suites hotels. The Construction :: The Construction : It has 57 electric elevator, the fast speed is 10 m / s. Owned by Emaar immovable, is one of the largest real estate companies in the world and had assumed the process of building the Samsung company and technology Some properties :: Some properties : The top of the tower includes a balcony view open to the public, as well as the highest mosque, and the highest restaurant, and the highest swimming pool, and a lot of apartments, offices, business people and beautiful scenery, antiques and rare graphics and wonderful jewelry. Some inside Picture:: Some inside Picture: Burj Khalifa in interesting number: Burj Khalifa in interesting number 95 – the distance in kilometers at which Burj Dubai’s spire can still be seen 124 – the floor location of ‘At The Top, Burj Dubai’, the world’s highest and only publicly accessible observation deck with an outdoor terrace 160 – the number of luxury hotel rooms and suites 605 – the vertical height in meters to which concrete was pumped in the construction of Burj Dubai, a world record for concrete pumping Burj Khalifa in interesting number: Burj Khalifa in interesting number 504 – the distance traveled, or ‘rise’ in meters of Burj Dubai’s main service lift, the most of any elevator 49 – the number of office floors, including the 12-floor annexure 57 – the number of elevators 1,044 – the total number of residential apartments inside Burj Dubai Burj Khalifa in interesting number: Burj Khalifa in interesting number 3,000 – the number of underground parking spaces 5,500 – the capacity in kilograms of the tower’s service lift 31,400 – the amount of steel rebar in metric tonnes used in the structure of Burj Dubai 28,261 – the number of glass cladding panels making up the exterior of tower and its two annexes Burj Khalifa in interesting number: Burj Khalifa in interesting number 15,000 – the amount of water in liters collected from the tower’s cooling equipment that will be used for landscaping irrigation 900 – the length in the feet of the world’s tallest performing fountain, The Dubai Fountain, that lies at the foot of the tower 19 – the number of hectares of lush green landscaping that envelops the foot of the tower 12,000 – the numbers of workers on site during peak of construction Burj khalifa Vs. some other famous buildings in the world …!!: Burj khalifa Vs. some other famous buildings in the world …!! Challenges : Challenges gives the steel structure of the tower, who took over his company Aeffersanda Malaysian, high flexibility of the tower in the face of the wind at an altitude of 828 meters or higher. The pay wind velocities at the top of the tower to be tilted at 4 degrees. But the construction techniques used by the Samsung was developed and gives the steel structure of the tower, the highest flexibility and allows it to tilt rod for more than 6 degrees (35 centimeters) horizontally and vertically winds Challenges: Challenges Samsung says that the degree of inclination that are not effective at all and will not be felt by the population because it occurred that you will be in the upper layers for services, that is in between floors and above the 160-story uninhabited. winds Challenges: Challenges According Pkering , the tower also bears strong winds with speeds up to 200 kilometers per hour, thanks to the durability of concrete and steel structure and strength compared to other skyscrapers in the world winds Challenges: Challenges In the Tower Khalifa , rather than fight the winds of speeds up to 200 km / h, the Bill and the design team decided to outwit the wind. The tower was not flat and rectangular, but they gave to the Khalifa Tower design is expected. Each section in the tower is designed to distort the wind in a different way, and this weakens the strength of vortices and breaks the force of the storm wind. winds Challenges: Challenges Khalifa tower can resist earthquakes, power up to seven degrees on the Richter scale because it has a concrete structure reinforced and tremendous. But engineers are facing a different problem here, construction of the giant building of this length on the sands of the desert requires special measures. Earthquake resistance Challenges: Challenges in the case of Tower Khalifa .. Rocks, shallow and very weak as it is unbreakable .. So you can not afford a lot of weight so the project went 70 meters deeper in the rocks to reach the rocks sufficient to support this structure. Earthquake resistance Challenges: Challenges Rock under the tower Khalifa fragile and saturated with groundwater, and any Stnglgl a big gap in those holes directly. To prevent this, the engineers mobilized drilling holes ventricle viscose polymer that drive groundwater and rock fragments to the edge of the drill hole to keep it open Earthquake resistance Video….: Video…. PowerPoint Presentation: Any question…!!
