Burj Khalifa is not just the world’s tallest structure, it has likewise broken two other amazing records: tallest structure, recently held by the KVLY-TV pole in Blanchard, North Dakota, and tallest unattached structure, recently held by Toronto’s CN Tower. The Chicago-based Council with respect to Tall Buildings and Urban Habitat (CTBUH) has set up 3 criteria to figure out what makes a tall structure tall. Burj Khalifa wins by a wide margin in each of the three classes.
Talness to Structural Top
Tallness is estimated from the dimension of the least, critical, outside, person on foot access to the structural top of the structure. This incorporates towers, however does exclude receiving wires, signage, flagpoles or other utilitarian specialized gear. This estimation is the most generally utilized and is utilized to characterize the Council on Tall Buildings and Urban Habitat rankings of the Tallest Buildings in the World.
Most Noteworthy Involved Floor
Stature is estimated from the dimension of the most minimal, critical, outside, passer by access to the most elevated constantly involved floor inside the structure. Upkeep territories are excluded.
Stature to Tip
Stature is estimated from the dimension of the most minimal, critical, outside, person on foot access to the most astounding purpose of the structure, independent of material or capacity of the most astounding component. This incorporates receiving wires, flagpoles, signage and other practical specialized hardware.
In May 2008 Putzmeister pumped concrete with more than 21 MPA ultimate compressive strength of gravel to surpass the 600 meters weight of the effective area of each column from the foundation to the next fourth level, and the rest was by metal columns jacketed or covered with concrete to a then world record delivery height of 606 m (1,988 ft), the 156th floor.
Over 45,000 m3 (58,900 cu yd) of concrete, weighing more than 110,000 tonnes (120,000 short tons; 110,000 long tons) were used to construct the concrete and steel foundation, which features 192 piles; each pile is 1.5 metre in diameter by 43 m in length, buried more than 50 m (164 ft) deep.The foundation was designed to support the total building weight of approximately 450,000 tonnes (500,000 short tons; 440,000 long tons).
Burj Khalifa’s construction used 330,000 m3 (431,600 cu yd) of concrete and 55,000 tonnes (61,000 short tons; 54,000 long tons) of steel rebar, and construction took 22 million man-hours.
Special mixes of concrete were made to withstand the extreme pressures of the massive building weight; as is typical with reinforced concrete construction, each batch of concrete was tested to ensure it could withstand certain pressures.
All Time Record Breaker
Some other World Records that Burj Khalifa holds are: highest residential apartments, highest base jump from a building, highest restaurant from ground level, tallest elevator in a building, most floors in a building etc.
Jeddah Tower, a skyscraper located in Saudi Arabia is predicted to be the building that by 2020 will knock Burj Khalifa, the Dubai’s legend, off its throne. Until then, our 830m tall icon of engineering will be the Queen of Structures.
