Burj Khalifa

design by Dóri Sirály for Prezi
Today in is presentation you will be learning some very interesting facts about the tallest structure in the world.There will be facts on the Burj Khalifa itself,it's purpose,the materials it used,how it resists forces and the external and internal forces that act on it.
Introduction
External and Internal forces.
Burj Khalifa
Purpose
The construction of the Burj Khalifa required 330,000 cubic meters of concrete.The foundation alone using over 45,000 cubic meters.The foundation consists of 192 piles of concrete which are buried 50 meters beneath the surface.31,400 metric tonnes of steel re bar were used to reinforce the concrete.In addition to concrete and steel the Burj Khalifa is made up of other materials too like glass,silicone,and aluminum which makes the outside of the building.
Materials
By:Riya
The purpose of the building Burj Khalifa was to diverse from oil-based economy to one that is service and tourism oriented.The purposes of the Burj Khalifa fall into 3 categories:commercial,residential,and hospitality.
It has been designed to be the centerpiece of a large-scale,mixed -use development that includes 30,000 homes,9 hotels,19 residential tower and the Dubai Mall.
To build the Burj Khalifa the only standard technique was built in shape of a 'Y' shaped plan.Each wing has it's own concrete wall and perimeter columns that buttress with a 6-sided central core.
Burj Khalifa 'the Khalifa Tower' known as the Burj Dubai before it's inauguration ,is a skyscraper in Dubai,United Arab Emirates(UAE).It was designed by Bill Baker.It is the tallest man-made structure in the world standing at 829.8m(2,722 ft).The construction started on January 6 2004 and it was completed on December 30 2010.The cost of the construction was USD 1.5 billion.
Damages
The Burj Khalifa is resistible to high winds and earthquakes because first of all it is 828.8m tall.To withstand this elements,the Burj Khalifa is designed with a buttressed core where 3 wings are set at 120 degrees to each other,made around a hexagonal contra club.This 6-sided shape is made to prevent the building from twisting.
Standard Technique
External Force-A major challenge was understanding the wind and how the building reacted for the building of this height and slenderness.Another thing is that there is a wind tunnel programmer that helps to determine the impact of the types of forces acting on the structures externally and the dynamic behavior measured in localized pressures and establishing a statistical model.
Internal Forces-The internal forces that on the structure are compression,torsion and live load.Compression acts on the structure when the concrete piles are compressed under the weight of the structure.Torsion acts on the structure because the structure goes in 2 different directions.Live Load acts on the structure internally because the load is supported by gravity that acts
on the center of the structure.
