The Regent Emirates Pearl Hotel Abu Dhabi, UAE

摘要

Located amongst palaces and high profile skyscrapers on the Corniche Street of Abu Dhabi in the United Arab Emirates, the new mixed-use $290 USD million Regent Emirates Pearl development rises and twist 840 feet (256 m) above ground. The expansive plot area of 120,000 sf (11,150 sm) is located such that it provides some of the best views of the capital city, the turquoise water of the Persian Gulf and the luxurious Emirates Palace. The structure topped out in March 2012 and will open in early 2014. The Pearl’s signature feature is the 45– story twisting elliptical floor plan and columns which contains 60 luxury serviced apartments occupying levels 1 thru 10 and a 5-star hotel with 437 rooms including presidential and royal suites occupying levels 11 thru Roof. (See Figure 1.) The expansive podium area includes five levels of restaurants, retail areas, spas, swimming pools, gym and more with another 5 levels of underground parking. The total project build up area is 55 stories and 1.4 million sf. The tower is laterally supported by an elliptical core-coupled shear wall and vertically supported by gravity columns twisting around the perimeter, oriented at 7 degrees from vertical. The inherent torsion which is driven into the core was greatly reduced by use of an innovative outrigger transfer design which reversed the torsion, making the building both possible and efficient. The use of a construction sequence model was used to verify the design and to provide direction regarding how best to construct the tower.
