It is an engineering wonder designed to dampen the vibrations of the 1,667-foot-tall structure. The 18-foot-diameter, 660-metric-ton steel sphere is hung by eight cables in the tower's top levels and can be seen from the 88th to 92nd floors.
The purpose is to reduce noise pollution and improve the viewing experience for people living or working near the site.
There are other towers in the world that use a spheroid as a vibration damper. The Shanghai World Financial Center uses one made of glass, while the Petronas Towers in Kuala Lumpur, Malaysia, use ones made of resin.
The Taipei 101 Tower's sphere was manufactured by GGG State-owned Steel Manufacturing Corporation in Jiangsu Province, China. It was delivered to Taiwan in 2004 and hoisted into place later that year. The sphere weighs about half as much as the tower it is attached to and contains 2.5 million cubic feet of air.
People who work on the 97th floor restaurant of the Taipei 101 Tower can see the sphere hanging in the distance. They say it looks like a giant ball of smoke when the wind is not blowing in the right direction. However, when the wind is howling, it looks like a huge wave crashing toward them.
1500 meters It is 1,500 feet tall as measured from the top of its antenna masts (457 m). The structure houses various businesses and restaurants, as well as around 700 condominiums, and at the time of its construction, it housed the world's tallest dwelling. It was built as a symbol of prosperity for the Chicago area and as an advertisement for the newly formed companyJohn Hancock Mutual Life Insurance Company.
Today, the antennas broadcast signals for radio frequency identification devices used by the United States Census Bureau to track the population distribution across the country. They also broadcast information relevant to the maintenance of the building's equipment, such as temperature changes inside its structure.
The original design called for twin 1500-foot-tall towers with helical antennas spiraling up their sides. However, construction costs exceeded budget, so only one tower was built. The completed tower is 456 feet high and has 48 floors. It was designed by Mies van der Rohe and Cesar Pelli and opened in 1969. It was the first major commission for both architects.
In addition to being a famous architectural landmark, the John Hancock Center is also known for being the home of the Chicago Bulls basketball team during the 1970s and 1980s. At the time, it was the largest arena in the NBA. The team moved out after the completion of the Chicago Stadium project in 1989.
1,667 meters Taipei 101, originally known as the Taipei Financial Center, is a commercial building in Taipei, Taiwan (Republic of China). The skyscraper has 101 storeys and a height of 1,667 feet, including the spire, designed by C.Y. Lee & Partners, a local architectural firm (508 metres). It is the second-highest building in Taiwan and the 13th tallest building in the world.
It was completed in 2004 and has been called "the highest shopping mall in Asia" because of its many luxury brands in its three floors of retail space. The tower's shape is based on that of a chrysanthemum, with each floor representing one of the bookends of the flower. The center section contains offices, while the top houses a revolving restaurant with panoramic views of the city.
Taipei 101 was the first supertall building in Taiwan and it opened to great success. The building's height makes it the third-highest in the city behind only two other skyscrapers: The 88-story Grand Hyatt Taipei and the 102-story Uniroyal Tire Building. The spire on top of the building was added in 2005 after the original design was rejected by the Taiwanese government as being too flashy.
The building is owned by the Chinese company Everbright International and was built with Wuhan University as part of a plan to have them collaborate on major projects. The project was announced in 2003 and construction began that same year.
The observation deck (named One World Observatory) occupies the 100th, 101st, and 102nd floors of the One World Trade Center. The tower measures 1,368 feet from the ground to the metal and glass railing on top of the structure, which was also the height of the Twin Towers. The observation deck has floor-to-ceiling windows that provide views of New York City, including Central Park, Brooklyn Bridge, Lower Manhattan, Ellis Island, and Governors Island.
In addition to the view, visitors can expect to experience a number of additional amenities at One World Observatory. These include a restaurant called American Kitchen by José Andres, a bar called Sky Bar, a lounge named Lounge 6, a coffee shop named Coffee Shop by Stewart Raff, a gift shop, a theater, and an art gallery. There are also planters outside the doors of some rooms that contain plants donated by different cities around the world.
FDR Memorial Library, also known as the "Tower of Books," is a library in Washington D.C., built in 1936-1937. It is located on the National Mall near the Lincoln Memorial. The library is part of the Federal Government Complex and is operated by the National Archives Institute/Library of Congress.
The FDR Library was designed by architect Louis Kamper who also designed the National Museum of Natural History across the street from the library.
