What is the tallest tower in the world?

Burj Dubai has set a number of world records, including the tallest building, the tallest independent building, the largest outdoor observation deck with the largest floor area, the tallest elevator and the tallest swimming pool. Burj Khalifa is too high to be described as a skyscraper, so the construction industry calls it a "super skyscraper". This 828-meter-high skyscraper in downtown Dubai was built in September 2004. Developed by aimar, a state-owned real estate company in the United Arab Emirates, designed by SOM architectural design company in the United States and built by Samsung products in South Korea. The base of Burj Khalifa is Islamic architecture style, with six Desert Flower petals. The whole building is Y-shaped, and the three architectural themes are gradually connected into a core, spiraling up, and the top is transformed into a steeple. Since the architectural drawings of Burj Dubai surfaced, its height has become a mystery. Bill Baker, a civil engineer who participated in the design of Burj Dubai, said: "We thought it would be slightly higher than Taipei 10 1, the tallest building in the world." Taipei 10 1 The building is 508 meters high. "[Developer aimar Real Estate] has been asking us to raise the design height, and even we don't know how high it will be in the end," Baker said. "We adjusted the design like an instrument, and the height kept rising ... Finally, the height of the building far exceeded our expectations." At the opening ceremony of 65438+10.4, the mystery was finally solved. The Burj Dubai is 828 meters high. At the same time, it was officially named "Alpha Tower". The Burj Dubai, with that world's fast elevator, has 65,438+069 floors (it is also report that it has 65,438+060 floors), which is made of 330,000 cubic meters of concrete and 365,438+040 tons of steel, and can be seen at least 95 kilometers away. The building has 1044 residential units, 49-storey office building and a luxury hotel, which is expected to accommodate 12000 people. The world's tallest Burj Dubai not only challenges the height limit, but also has the world's tallest and fastest "intelligent" elevator, which can reach the "top" of the world's tallest outdoor observation deck on the124th floor in one minute. On sunny days, visitors can overlook the scenery 80 kilometers away. Burj Dubai has 57 elevators, which are the longest elevators in the world and installed in different areas of the tower. Tourists, residents, office workers and hotel guests use different elevators. There are no direct elevators on all floors 160 in the tower, and there are "transfer areas" on floors 43rd, 76th and123rd. The main elevator in the center of the tower is 504 meters high, ranking first in the world, exceeding the record of 448 meters in Taipei 10 1 building elevator, and almost 1.5 times as high as the elevator in Empire State Building (38 1 meter). It is worth mentioning that there is a swimming pool on the 76th floor of Burj Khalifa, making it the highest swimming pool in the world. In addition, developers have a bolder idea. They plan to build a mosque on the 158 floor. Burj Dubai remains stable in strong winds, with a height of 828 meters, and needs a solid foundation to support buildings weighing more than 500,000 tons on the ground. Burj Dubai is built on a triangular base with a thickness of 3.7 meters, and is supported by 192 steel pipe piles or columns with a diameter of 1.5 meters. These steel pipe piles or cylinders are 50 meters underground.
