Concrete surrounds all stairwells and the building service and firemans elevator will have a capacity of 5500kg and will be the worlds tallest service elevator.
The superstructure of Burj Khalifa is supported over a large reinforced concrete raft. At the pinnacle the central core emerges and is sculpted to form a spire. The Burj Khalifa is one of the greatest concrete structures ever built.
BURJ KHALIFA WORLDS TALLEST STRUCTURE DrNSubramanian Consulting Structural Engineer Maryland USA. The weight of aluminum used on the Burj Khalifa is equivalent to that of five A380 aircraft. The grade of concrete raft.
Tower Form and Concept Overview Structural System Foundation Lateral Resisting System Loads. The initial concept for the design of the Burj Khalifa originated from the hymenocallis flower and spiral minarets that are an important part of Islamic architecture. The raft has a thickness of 37m and was constructed in four separate pours.
It consists of series high-strength reinforced concrete walls. Putzmeisters specially designed BSA 14000 SHP-D reached a world record vertical concrete pumping height of 1988 feet 606m topping out. The building was opened in 2010 as part of a new development called Downtown Dubai.
Construction of the Burj Khalifa began in 2004 with the exterior completed five years later in 2009. Only 4 men died during its construction. The construction of this 828 m tall reinforced concrete tower structure broke several records during its construction.
A length of 600 m of high-pressure ZX 125 delivery pipe was laid out horizontally with transducers to measure concrete pressure after pumping through distances of 250 450 and 600 m Figure 3. The BurjKhalifa Tower is a multi-purpose ultra-high skyscraper was successfully completed in a record time by the joint venture of Samsung BeSix and ArabTec sponsored by Emaar Properties.

Fire safety and speed of evacuation were prime factors in the design of Burj Khalifa. The critical Independent Verification and Testing Agency IVTA role on the 160-plus storey Burj Khalifa was led by concrete specialist Dr James Aldred who is now the Technical Director of Concrete Future. This raft is in turn supported by bored reinforced concrete piles.
At the construction site of the Burj Khalifa the worlds tallest building concrete was pumped to a record height of 606 meters m. A strong central core is connected to three building wings. The primary structure is reinforced concrete.
It is designed to be the centrepiece of large-scale mixed-use development. The raft has a thickness of 37m and was constructed in four separate pours. The superstructure of Burj Khalifa is supported over a large reinforced concrete raft.
A strategically designed concrete pumping system made the final conveying height a reality as the concrete flowed through several stages up the 828-m tower. Concrete pumping trials were conducted before the Burj Khalifa tower construction using a Putzmeister BSA 14000 HP-D stationary pump with a maximum hydraulic pressure of 310 bar. As it rises from a flat base setbacks occur at each element in an upward spiraling pattern reducing the towers mass as it reaches skyward.
More than 110000 tons of concrete 55000 tons of steel rebar is use and 22 million man-hours to complete the Burj Khalifa. This raft is in turn supported by bored reinforced concrete piles. La position des ailes forment un escalier en colimaçon à gauche direction entourant le bâtiment et sert à contrer les vents forts et les tempêtes de sable nombreux à Dubaï.
Built of reinforced concrete and clad in glass the tower is composed of three elements arranged around a central buttressed core. Similar to Burj Khalifa as each wing is buttressed by the other two therefore the stability of the structure is greatly enhanced. The grade of concrete raft.
