Title: ………………………………………………………………………………..Introduction:The Burj Khalifa it is the tallest tower in the world, which rises into the Dubai skyline at 828 metres. The project took six years (2004-2010) to complete and cost approximately $1.5 billion. It represents the collaboration and coordination of many individuals from around the world in the construction profession. New methods have been developed to build this tower due to its height, weight and Dubai's high temperatures. Advanced techniques were introduced to help raise this skyscraper and break all height records, including the long-standing record of the Twin Towers. This essay will first present the idea behind building a tower in Dubai, then discuss the problems with the building materials used and how the problems were solved. Next, we will discuss how the wind almost erased the existence of the Burj Khalifa. History: In 2003 Emaar, one of Dubai's leading real estate companies, announced the construction of a new tower in Dubai's financial district, destined to become the center financial institution of the Middle East, thus strengthening Dubai's plans to become the "capital" city of the world. Furthermore, Emaar planned to build a unique tower to attract customers to invest in the tower itself and in the Dubai market. The tower was called Burj Dubai and was expected to be completed by 2009. In February 2004, construction began on the Burj site. Meanwhile, the economic crisis had hit Dubai, leaving many developers bankrupt. Abu Dhabi, the capital of the United Arab Emirates, has decided to finance up to $10 billion for ongoing projects in Dubai, including Burj Dubai. In return the Burj Dubai changed its name to Burj Khalifa, named after Sheikh Khalifa Bin Zayed, the ruler of Ab......middle of paper......the Burj was designed with smooth, rounded edges as well as reduced width at higher levels. This design eliminated the possibility of wind shedding from the sides dragging the tower from side to side. The tower was also reoriented to the prevailing wind direction. The design of the Burj does not allow the wind to create transverse forces and therefore the tower is very stable. The external balconies of the Burj are also at great risk as the winds will be very dangerous for a person standing on an unprotected balcony. Therefore, the balconies were equipped with glazed balustrades, which prevented the wind from blowing directly through the balcony. They were also equipped with windbreaks, which prevent the wind from passing over the balustrades and the balcony surface. In addition, pylons have been installed to prevent wind blowing from the top of each balcony.
