Which type of structural system is used in Burj Khalifa?
The structural system employed for Burj Khalifa can be called as the Buttressed Core System. The whole system is constructed by using high performance concrete wall. Each wing buttresses the other through a hexagonal central core as shown in figure-2.
What is buttressed core system?
Buttressed core is a structural system for high buildings, consisting of a hexagonal core reinforced by three buttresses that form a Y shape.
Is Burj Khalifa a steel or RCC?

How does the Burj Khalifa resist wind?
Reflective glass – oscillation and repeated thermal stress caused by the expansion and contraction of the air between the inner and outer glass panels. Diagonal steel bracing.
Is Burj Khalifa steel structure?
In total, 330,000m3 of concrete and 39,000 tonnes of steel rebar were used in constructing Burj Khalifa. The very top of the 828m spiral structure required a deck that was both high quality and which would be suitable for installation at such a height.
What material is the Burj Khalifa made out of?
In addition to concrete and steel, other major materials used are glass, silicone, and aluminum, which make up the outside façade of the tower. In massive structures like the Burj Khalifa, the concrete used in construction must be able to withstand the thousands of tonnes bearing down on it.
Why is the Y shape of the Burj Khalifa important?
In addition to its aesthetic and functional advantages, the spiralling “Y” shaped plan was utilized to shape the structural core of Burj Khalifa. This design helps to reduce the wind forces on the tower, as well as to keep the structure simple and foster constructability.
What are transfer beams?
Transfer beams transfer heavy and concentrated loads through shear. In order to avoid progressive collapse, the transfer beam should be cast monolithically and continuously while spanning over several supports. The structural system should also provide an alternative load path for load path redundancy.
How many piles are there in Burj Khalifa?
Over 45,000 m3 (58,900 cu yd) of concrete, weighing more than 110,000 tonnes were used to construct the concrete and steel foundation, which features 192 piles buried more than 50 m (164 ft) deep.
Who supplied steel for Burj Khalifa?
Tata Steel
From the Howrah Bridge in 1943 to the Burj Khalifa in 2010, Tata Steel has helped raise iconic structures in India and abroad. These metal marvels have become proud symbols of city skylines around the world.
How does the Burj Dubai building deal with high winds?
If you were near the top of the world’s tallest skyscraper — the Burj Khalifa in Dubai, which has 163 floors — you would feel the building sway about two metres! This steel makes up the “skeleton” of the skyscraper. It stops the tall building from swaying too much, helping the structure withstand heavy winds.
What makes the Burj Khalifa strong and stable?
The modular, Y-shaped structure, with setbacks along each of its three wings, provides an inherently stable configuration for the structure and provides good floor plates for residential. Twenty-six helical levels decrease the cross-section of the tower incrementally as it spirals skyward.
What is the structural system employed for Burj Khalifa?
The structural system employed for Burj Khalifa can be called as the Buttressed Core System. The whole system is constructed by using high performance concrete wall. Each wing buttresses the other through a hexagonal central core as shown in figure-2.
What makes Dubai’s Burj Khalifa so special?
The cladding system is designed to withstand Dubai’s extreme summer heat and to ensure its integrity further, a World War II aeroplane engine was used for dynamic wind and water testing. The curtain wall of Burj Khalifa is equivalent to 17 football (soccer) fields or 25 American football fields.
What type of concrete is used in Burj Khalifa?
There is periodic encounter of outrigger system through the height of the tower. The high-performance concrete used in Burj Khalifa guarantee low permeability and higher durability. The C80 and C60 cube strength concrete is used incorporating fly ash, Portland cement, and the local aggregates.
How many terraces are there in the Burj Khalifa?
The structure consists of 26 terraces. The Burj Khalifa employs a ‘Y’ shaped floor plan. This plan provide higher performance and provides a full view of the Persian Gulf. The shape and the upward setbacks help the structure to reduce the wind forces that is acting on the structure.
