Skyscrapers, Damping Systems, and Physics

Skyscrapers are wonderful. The building failed. Wonder of the world How can they withstand the strongest winds and earthquakes? Today, engineers rely on damping systems to counteract the power of nature. Engineers can now use different types of damping systems for structures, automobiles, and even tennis rackets. This site focuses on structural changes in the damping system in the structure, mainly tuned mass dampers. How the tuned mass damper works The synchronized mass damper (TMD) consists of a mass (m), a spring (k), and a vibration damping device (c) and measures the energy energy (usually one form) I will dissipate.

Tall buildings are high-rise buildings with many floors. Buildings can be classified as skyscrapers without precise definition, floor or height. Sometimes, if a relatively small building protrudes above the surrounding building and changes the skyline of the whole city, it can be regarded as a skyscraper. Skyscrapers are usually designed for office or commercial use and there are steel frames that support the curtain wall. Prior to the 19th century, buildings with more than 6 stories were rare because the climb was too high, the water pressure was usually too low, and the water did not reach the upper floors. However, from ancient times, people tried to build high-rise buildings such as the pyramids of Giza in ancient Egypt, the Lincoln Cathedral of the 14th century, the Washington Monument of the 19th century, but because nobody lives, can not.

The first skyscraper - a skyscraper or skyscraper high-rise building - appeared from the late nineteenth century to the early twentieth century. The Chicago family insurance building was completed in 1885 and is often considered the first modern skyscraper, but the height is only ten floors. Later, higher buildings became possible through a series of architectural and engineering innovations, including inventions of the steel's first large-scale production. Today, the highest skyscraper in the world is close to 2,000 feet, even more than 2,000 feet

The general feature of a skyscraper is a steel frame hanging a curtain wall, not a traditional structured wall. Because most high-rise buildings use steel frames, they are taller than the load-bearing walls of general reinforced concrete. Skyscrapers are usually small in surface area, often considered walls. Since the walls are not heavy, most skyscrapers are characterized by the surface area of ​​the windows provided by the steel frame and curtain wall concept. However, high-rise buildings can also have curtain walls imitating traditional walls, the window surface area is small.
