Transcript of THE BURJ KHALIFA

THE BURJ KHALIFA
INTRODUCTION:
Hi, my name is Athar. We are learning about Structures in Science. I researched on the Burj Khalifa.Burj means "tower" in Arabic.The construction for the Burj Khalifa started in 2008 and was built in 2010 by Sheikh Muhammed and Sheikh Khalifa .(Sheikh Muhammed is currently the Vice President of U.A.E). The Burj Khalifa is 829.8 metres!(2,722 feet).The Burj Khalifa is the tallest structure in the world. My six inquiry questions are: What was the purpose of building the Burj Khalifa, Is the Burj Khalifa the tallest free-standing structure in the world, What is the Burj Khalifa used for, What materials and construction techniques were used to build The Burj Khalifa, How will The Burj Khalifa be able to withstand Natural Disasters, and What standard building techniques were used to ensure that The Burj Khalifa can withstand forces placed upon it.


HOPE YOU ENJOY!☺
WHAT WAS THE PURPOSE OF BUILDING THE BURJ KHALIFA?
The main purpose of building The Burj Khalifa is because Sheikh Muhammed wanted something attracting and really sensational in the city of Dubai. The decision to build the Burj Khalia went on as a very big issue that had been reported to the Government of U.A.E(United Arab Emirates). Then the Government said that for the honour of Sheikh Muhammed the vice president they are going to build The Burj Khalifa. So then, they hired some workers to build The Burj Khalifa .The decision to build the Burj Khalifa was reportedly based on the government's decision to diversify from an oil-based economy that was tourism-oriented. Adrian Smith the design architect said that the triple lobed footprint of the Burj Khalifa was inspired by the Hymenocallis flower.
WHAT IS THE BURJ KHALIFA USED FOR?
The Burj Khalifa is a resedential and commercial building with an attached shopping mall. The Burj Khalifa was also built for tourism purposes. Fazlur Rahman Khan invented the bundled up-tube that was used to build the The Burj Khalifa
.
The Burj Khalifa was designed as the center-piece of a large-scale. The use of the development that includes 30,000 homes, nine hotels, 3 hectares of parkland, 19 residential towers, the famous Dubai Mall, and the man-made Burj Khalifa Lake.
WHAT MAKES THE BURJ KHALIFA DIFFERENT FROM OTHER STRUCTURES?
The Burj Khalifa is different from other structures because it is made in a shape of a Hymenocallis flower. The way that the Burj Khalifa was built was that it was made like a very broad staircase shape that also gives it the main support. The Islamic architecture patterns were also used to build the Burj Khalifa. The Burj Khalifa's peak consumes 50MVA electricity which is similarly equivalent to 500,000,100 watt light bulbs. The construction to build The Burj Khalifa started in 2009 and ended on 2011. The Burj Khalifa was designed by Skidmore, Owings and Merril who also designed The Willis Tower in Chicago, USA. The tip of the spire is more than 0.5 miles above the ground.
HOW DOES THE BURJ KHALIFA BE ABLE TO WITHSTAND NATURAL DISASTERS?
The Burj Khalifa is resistable to high winds and earthquakes, especially that The Burj Khalifa is 828m tall. To withstand these elements, The Burj Khalifa is designed with a butressed core, where three wings are set at 120 degrees to each other, made around a hexagonal-central hub. This six-sided core is made up of concrete and is like an axle, preventing the building from twisting. Each wing supports the others, so when the wind blows on two of the wings, the third wing resists the force. The different steps in The Burj Khalifa's shape ensures that the wind flow is disrupted.
WHAT MATERIALS & CONSTRUCTION TECHNIQUES WERE USED TO BUILD THE BURJ KHALIFA?
The materials of construction of the Burj Khalifa required 330,000 cubic meters of concrete, the foundation using over 45,000 cubic metres, the foundation consisted 192 concrete piles, which are buried 50 meters beneath the surface. 31,400 metric tons of steel rebar were used to reinforce the concrete. All this rebar laid end to end would stretch over more than a quarter of the Earth. In addition to concrete and steel, other major materials used are glass, silicone, and aluminum, which make up the outside facade of The Burj Khalifa. The construction techniques that were used was the Hymenocallis flower shape that was shaped like a triangle and triangles are a very strong shape. Another construction technique that was used to build the Burj Khalifa was that most of the Islamic symbols are triangolic so that is why the triple-lobed footprint was used.
