This design helps to reduce the wind forces on the Lateral load resisting system and floor framing system are the two major components of the superstructure of the Burj Khalifa Tower and these systems are discussed below. The Tower foundations consist of a pile supported raft. 3.22 shows a typical floor plan of the tower, a buttress core system was used as the major structural system for this supertall tower. Construction of the tower was started in 2004. The building officially opened on 4 January 2010. Burj Khalifa structural health monitoring Strainstall completed a monitoring contract on the tallest man-made structure ever built - the Burj Khalifa Tower in Dubai. The Burj Khalifa’s structural system was cre-ated with a conscious effort to conform to and [62] Civil Engineering OCTOBER 2012 ©SOM, ALL FOUR The Burj Khalifa’s structural system was created with a conscious effort to conform to and complement current construction technology. Its reinforced concrete structure makes it stronger than steel-frame skyscrapers. 3.1 Lateral Load Resisting System. The crowning glory of Burj Khalifa is its telescopic spire comprised of more than 4000 tons of structural steel. It consists of series high-strength reinforced concrete walls: a strong central core is connected to three building wings. The spire was constructed from inside the building and jacked to its full height of over 200 metres using a hydraulic pump. Burj Khalifa has got a hexagonal concrete core with an innovative system of Y-shaped buttresses which has been incorporated to give this building a stable and unique “tripod like” stance. The piles are 1.5 meter in diameter and approximately 43 meters long with a design capacity of 3,000 tonnes each. Outriggers at the mechanical floors allow the columns to participate in the lateral load resistance of the structure; hence, all of the vertical concrete is utilized to support both gravity and lateral loads. The structure of Burj Khalifa was designed to behave like a giant column with cross sectional shape that is a reflection of the building massing and profile. Other Names. At 828 meters in height, the Burj Khalifa is the tallest building in the world. Overcoming this problem was a challenge and a great inovation to the world of structural … 2 STRUCTURAL SYSTEM BRIEF DESCRIPTION 2.1 General The Burj Khalifa project is a multi-use development tower with a total floor area of 460,000 square meters that includes residential, hotel, commercial, office, entertainment, shopping, leisure, and parking facilities. The building officially opened on 4 January 2010. Structural System In addition to its aesthetic and functional advantages, the spiraling “Y” shaped plan was utilized to shape the structural core of Burj Khalifa. The Khalifa's Tower and Podium structures are currently under construction (Figure 3) and the project is scheduled for topping out in 2008. When the rebar cage was placed in the piles, special attention was paid to orient the rebar cage such that the raft bottom rebar could be threaded through the numerous pile rebar cages without interruption, which greatly simplified the raft construction. The setbacks are organized in conjunction with the tower’s grid: the stepping is achieved by aligning columns above with walls below to provide a smooth load path. The two wings enclose space in center to form largest atrium in the world standing about 180m height. Burj Khalifa is the first mega-high rise in which certain elevators are programmed to permit controlled … The setbacks are organized with the Tower's grid, such that the building stepping is accomplished by aligning columns above with walls below to provide a smooth load path. Beyond its record-breaking height, the Burj Khalifa incorporates new structural and construction efficiencies to reduce material usage and waste. At 828 meters in height, the Burj Khalifa is the tallest building in the world. Phase I; 23 Boreholes (three with pressuremeter testing) with depths up to 90m. Burj Khalifa - Major Structural System It is correct to say that nowadays the Burj Khalifa represents the concept of excellence in building design. After getting information directly of the website about the construction of Burj Khalifa, we were able to understand more about the structural system within the building. At the pinnacle, the central core emerges and is sculpted to form a spire. Its reinforced concrete structure makes it stronger than steel-frame skyscrapers. The spiraling “Y” shaped plan was used to reinforce the structural core of Burj Khalifa. Photo of the Completed Burj Khalifa The structure of Burj Khalifa was designed to behave like a giant column with cross sectional shape that is a reflection of the building massing and profile. Photo of the Completed Burj Khalifa The structure of Burj Khalifa was designed to behave like a giant column with cross sectional shape that is a reflection of the building massing and profile. An image of the Burj Khalifa is shown in Figure 1. The center hexagonal reinforced concrete core walls provide the torsional resistance of the structure similar to a closed tube or axle. structural system of the Burj Khalifa acts like a single unit creating a tower that acts as one giant concrete beam cantilevering from the ground.
