The elevators are actually air-tight capsules, pressure-controlled for passenger comfort.Īrchitects' Statement THE EARTH AND SKY. Two high-speed elevators reach a maximum speed of 1,010 meters/minute (55 feet/second) when traveling to the 89th floor. Located on floors 89 and 91, the observation decks include the highest restaurant in Taiwan. The system transfers the energy from the building to the swinging sphere, providing a stabilizing force. The 660 ton spherical steel mass is suspended between the 87th and 92nd floors, visible from the restaurant and observation decks. To counter unwanted movement within the skyscraper, a tuned mass damper (TMD) is incorporated into the structure. The green glass curtain wall brings the color of nature into the sky.ĭesigning a building this large presented unique challenges, especially since Taiwan is subject to typhoon winds and ground-shattering earthquakes.

Collapses in Japan prompted engineers to construct the Burj with the capacity to withstand a 7.0 magnitude earthquake, and the collapse of the World Trade Center Towers in New York City forever changed the design of tall buildings. Could occupants ever be evacuated quickly in the event of an extreme fire or explosion? How well would a skyscraper this tall withstand a fierce storm or earthquake? Engineers for the Burj Kahalifa claim that the building design incorporates multiple safety features, including a hexagonal core with Y-shaped buttresses for structural support concrete reinforcement around stairways 38 fire- and smoke-resistant evacuation lifts and the world's fastest elevators.Īrchitects learn from the design failures of other skyscrapers.

The extreme height of the Burj Khalifa raises safety concerns. No expense was spared for the building's opening ceremonies and a fireworks display every New Years. During a time of economic slowdown, the Dubai Tower has become an icon for wealth and progress in this city on the Persian Gulf.
