Vanity Height
Vanity height is defined by the Council on Tall Buildings and Urban Habitat (CTBUH) as the height difference between a skyscraper's pinnacle and the highest usable floor (usually observatory, office, restaurant, retail or hotel/residential). Because the CTBUH ranks the world's tallest buildings by height to pinnacle, a number of buildings appear higher in the rankings than they otherwise would due to extremely long spires. The controversy began when the Petronas Towers were named the world's tallest buildings in 1998, despite having a roof 63.4 m (208 ft) lower than that of the Willis Tower. The world's tallest building, Burj Khalifa, is officially 828 meters tall, but its highest usable floor is 585m above ground. Therefore, its vanity height is 244 meters or 29% of the building's total height. Without this vanity height, the Burj Khalifa would still be the tallest building in the world, but only exceeding the Shanghai Tower's highest usable floor by 2 meters. The n ...

Comparison Of Vanity Height
Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and the arts. General usage Comparison is a natural activity, which even animals engage in when decidin ...

Council On Tall Buildings And Urban Habitat
The Council on Tall Buildings and Urban Habitat (CTBUH) is an international body in the field of tall buildings, including skyscrapers, and Sustainable design, sustainable urban design. A non-profit organization based at the Monroe Building in Chicago, Illinois, United States, the CTBUH announces the title of "The World's Tallest Building" and is widely considered to be an authority on the official height of tall buildings. Its stated mission is to study and report "on all aspects of the planning, design, and construction of tall buildings." The CTBUH was founded at Lehigh University in Bethlehem, Pennsylvania in 1969 by Lynn S. Beedle, where its office remained until October 2003 when it relocated to the Illinois Institute of Technology in Chicago. Ranking tall buildings The CTBUH ranks the height of buildings using three different methods: #Height to architectural top: This is the main criterion under which the CTBUH ranks the height of buildings.

World's Tallest Buildings
This is the History of the world's tallest structures. Overall Below is a list of the tallest structures supported by land. For most of the period from around 2650 BC to 1240 AD, the Egyptian pyramids (culminating in the Great Pyramid of Giza) were the tallest structures in the world. From 1240-1884 the records were held by European churches, and from 1954-2008 they were held by guyed radio or TV masts. Since 2008, a skyscraper in Dubai called the Burj Khalifa has been the tallest structure supported by land, at 829.8 metres (2,722 feet). Although oil platforms supported by the sea have been the taller since about 1980, with some examples up to 2,934 metres (9,627 feet). And some countries monitor their borders with tethered aerostats which can rise to 6,096 metres (20,000 feet). The Kanishka Stupa near Peshawar, Pakistan was built c. 151 and rebuilt in the 4th century. Ancient travelers claimed it was up to 171 metres (560 feet) tall, which would've been a rec ...

Spire
A spire is a tall, slender, pointed structure on top of a roof of a building or tower, especially at the summit of church steeples. A spire may have a square, circular, or polygonal plan, with a roughly conical or pyramidal shape. Spires are typically made of stonework or brickwork, or else of timber structures with metal cladding, ceramic tiling, roof shingles, or slates on the exterior. Since towers supporting spires are usually square, square-plan spires emerge directly from the tower's walls, but octagonal spires are either built above a pyramidal transition section called a '' broach'' at the spire's base, or else free spaces around the tower's summit for decorative elements like pinnacles. The former solution is known as a ''broach spire''. Small or short spires are known as ''spikes'', ''spirelets'', or '' flèches''. Etymology This sense of the word spire is attested in English since the 1590s, ''spir'' having been used in Middle Low German since the 14t ...

History Of The World's Tallest Buildings
The tallest building in the world, is the Burj Khalifa in Dubai, United Arab Emirates. The title of " world's tallest building" has been held by various buildings in modern times, including Lincoln Cathedral in Lincoln, England, and the Empire State Building and the original World Trade Center, both in New York City. Before the modern skyscraper era emerged, between 1311 and 1884 the tallest buildings and structures were mostly Christian churches and cathedrals. Prior to then, the tallest buildings in the world cannot be conclusively determined. For instance, the Lighthouse of Alexandria, which was completed in approximately 280 BC, has been estimated to have been tall, but its true height is not known. For thousands of years, the Great Pyramid in Egypt was the tallest ''structure'' in the world until Lincoln Cathedral of 1311, but the Great Pyramid is not considered a building since it is not habitable. Similarly, the Eiffel Tower was the world's tallest structure from 1889, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communications Tower
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. A mast radiator or radiating tower is one in which the metal mast or tower itself is energized and functions as the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guy-wires. ; A ''mast'': is a guyed mast, a thin structure without the shear strength to stand unsupported, that uses attached guy lines for stability. They may be mounted on the ground or on top of buildings. Typical ''masts'' are of steel lattice or tubular steel const ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tallest Buildings
This is a list of the tallest buildings. Tall buildings, such as skyscrapers, are intended here as enclosed structures with continuously occupiable floors and a height of at least . Such definition excludes non-building structures, such as towers. History Historically, the world's tallest man-made structure was the Great Pyramid of Giza in Egypt, which held the position for over 3,800 years until the construction of Lincoln Cathedral in 1311. The Strasbourg Cathedral in France, completed in 1439, was the world's tallest building until 1874. The first building considered to be a skyscraper was the Home Insurance Building, built in Chicago in 1885. The United States would remain the location of the world's tallest building throughout the 20th century until 1998, when the Petronas Towers were completed. Since then, two other buildings have gained the title: Taipei 101 in 2004 and Burj Khalifa in 2009. Since the beginning of the 21st century, the Middle East, China, and Southe ...
