The Capital Gate, also known as the Abu Dhabi Leaning Tower, is a high-rise building in Abu Dhabi that is more than 160 meters (520 ft) tall, 35 stories high, with more than 16,000 square meters (170,000 sq ft). ) used in the office. Capital Gate is one of the tallest buildings in the city and is designed to slide 18 ° to the west. The building is owned and built by the Abu Dhabi National Exhibitions Company. The tower is the focal point of the Capital Center.
The Capital Gate ‘Feature Tower’ is an iconic development found in the exhibition area of the great masterplan of ADNEC. The tower is made of stainless steel and glass with a striking biological form. With its tea-lined tea lounge and open-air deck, it offers a unique presence in the sky of Abu Dhabi and creates a memorable space in the exhibition center. The stainless steel ‘plash’ slides down the front and the lower level forms the roof of the hotel’s entrance, flows over a large local seat, and serves as a solar flare tool in both the building and the grandstand seat. The free form is an internal atrium with a moving glass roof that brings natural light and space into the tower. Outdoor lighting is designed to reduce low light pollution and energy consumption, based on the combination of low landscape lighting with façade lamps that contain a net of compact LED clusters integrated into the glazing metal system. Over 160m in height, the building is 35 floors high and offers more than 16,000 sqm of high-quality office space, as well as the first Abu Dhabi Hyatt hotel
The building is based on the foundation of 490 pilings excavated 30 meters (98 ft) underground. Deep pilings provide stability compared to strong winds, gravitational force, and seismic pressure resulting from a building tilt. Of the 490 pilings, 287 is 1 meter (3 ft 3 in) wide and 20 to 30 meters (66 to 98 ft) deep, and 203 is 60 inches (24 in ) width and 20 meters (66 ft) depth. All 490 piles were piled together using a reinforced concrete slab approximately two feet (6.6 ft) deep. Some of the piles were pressed at first while construction supported the lower floors of the building. Now they are in trouble as the extra pressure caused by the overhang has been applied.
CORE OF THE STRUCTURE:
The Capital Gate theme was built using jumping formwork, also known as climbing formwork. The central concrete foundation had to be specially designed to accommodate the maximum strength created by the building’s angle of elevation or camber. The spine consists of 15,000 cubic meters (20,000 cu yd) of concrete reinforced with 10,000 tons of steel and using a straight vertical junction and constructed with a standing pre-camber. This pre-camber means that the context is constructed with a slight opposite dependence. When each floor was installed, the floor weight with a split grid, or diagrid, the system pulled the core and guided it slightly. The total consists of 146 vertical steel muscles, each 20 meters (66 ft) long, used for back fractures.
Given the 18 ° leaning of the building, the construction required two diagrid systems: an external drawing describing the structure of the tower and an internal drawing connected to the center by eight separate elements, connected by pins. The outer diagram contains 720 sections of various scenarios, based on the reference on which the tower rests. The outer grid carries a lower weight while the inner drawing connects to the outer and transfers the load to the part, thus eliminating the need for columns on the floor. Structurally, this challenging building resides on a massive distribution of 490 pits dug up to 30 meters underground to provide gravity, wind, and earthquakes created by the unique dependence of the structure. The Feature Tower is an example of RMJM design and in-house engineering skills.
In June 2010, Guinness World Records adopted the Capital Gate tower as the world’s most dependable building. A new record shows that the Capital Gate tower was built 18 ° west, four times the size of Suurhusen’s Leaning Tower. Guinness World Records recognition was awarded by an award committee appointed by Guinness in January 2010, when the cover was completed. In January 2010 the Capital Gate in Abu Dhabi was recognized as the world’s tallest man-made tower by the Guinness Book of World Records.
DESIGN AND ARCHITECTURE:
The building has a design specifically designed to capture and transmit energy generated by wind and earthquake, as well as the gradient of Capital Gate. Capital Gate is one of the few paintings in the world. Others include St Mary Ax (Gherkin) of London 30, Hearst Tower of New York, and National Stadium in Beijing. Capital Gate was designed by the construction company RMJM and completed in 2011. The tower covers 16,000 square meters (170,000 sq ft) of office space and the Andaz Hotel on the 18th to 33rd floor.
