Slenderness
In architecture, the slenderness ratio, or simply slenderness, is an aspect ratio, the quotient between the height and the width of a building. In structural engineering, slenderness is used to calculate the propensity of a column to buckle. It is defined as l/k where l is the effective length of the column and k is the least radius of gyration, the latter defined by k^2=I/A where A is the area of the cross-section of the column and I is the second moment of area of the cross-section. The effective length is calculated from the actual length of the member considering the rotational and relative translational boundary conditions at the ends. Slenderness captures the influence on buckling of all the geometric aspects of the column, namely its length, area, and second moment of area. The influence of the material is represented separately by the material's modulus of elasticity E. Structural engineers generally consider a skyscraper as slender if the height:width ratio exceeds 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Highcliff
Highcliff is a luxury apartment building on a south slope of Happy Valley on Hong Kong Island in Hong Kong. The 75-storey building's construction (70 floors of which are liveable space) began in 2000 and was completed in 2003 under a design by DLN Architects & Engineers. It was the Silver Winner of the 2003 Emporis Skyscraper Award, coming in second to 30 St Mary Axe in London. The tower is the tallest "all"-residential building in Hong Kong island. Highcliff is thin for such a tall building; it has a slenderness ratio of 1:20 thus being one of the thinnest buildings in the world. Therefore, a passive wind damper was fitted to the top, the first of its kind for a residential building. This was installed because typhoons approach Hong Kong most late summers. Because of the obvious similarity with a nearby similar building The Summit, the two have been informally called "The Chopsticks". These two buildings highlight the characters of pencil-thin towers that are highly con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pencil Tower
A pencil tower (also known as a skinny skyscraper, pencil-thin tower, super-slender tower, or super-slim tower) is a high-rise building or skyscraper with a very high slenderness ratio, meaning it is very tall while being very thin. There is no universal definition of how slender these buildings are to be categorized, but some definitions of 10:1 or 12:1 ratios and higher have been used. Hong Kong started developing pencil towers in the 1970s. Residential buildings of twenty or more stories with one unit per floor were built over small lots. It has become one of the most common types of buildings in the city, making Hong Kong the world's highest concentration of pencil towers. Hong Kong's most notable towers are the 72-story Highcliff Tower, which has a slenderness ratio of 20:1, and its neighbor, The Summit (Hong Kong), The Summit, a 65-story residential building. In the 2010s, pencil towers became a new phenomenon of building design in New York City. The newer pencil towers on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Icons are most commonly painted on wood panels with egg tempera, but they may also be cast in metal or carved in stone or embroidered on cloth or done in mosaic or fresco work or printed on paper or metal, etc. Comparable images from Western Christianity may be classified as "icons", although "iconic" may also be used to describe the static style of a devotional image.

Sky House
The sky is an unobstructed view upward from the surface of the Earth. It includes the atmosphere and outer space. It may also be considered a place between the ground and outer space, thus distinct from outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an abstract sphere, concentric to the Earth, on which the Sun, Moon, planets, and fixed stars, stars appear to be Diurnal motion, drifting. The celestial sphere is conventionally divided into IAU designated constellations, designated areas called constellations. Usually, the term ''sky'' informally refers to a perspective from the Earth's surface; however, the meaning and usage can vary. An observer on the surface of the Earth can see a small part of the sky, which resembles a dome (sometimes called the ''sky bowl'') appearing flatter during the day than at night. In some cases, such as in discussing the weather, the sky refers to only the lower, denser layers of the atmosphere. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
