Slenderness Ratio
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] |

Icon (building)
An icon () is a religious work of art, most commonly a painting, in the cultures of the Eastern Orthodox, Oriental Orthodox, and Catholic churches. They are not simply artworks; "an icon is a sacred image used in religious devotion". The most common subjects include Christ, Mary, saints and angels. Although especially associated with portrait-style images concentrating on one or two main figures, the term also covers most religious images in a variety of artistic media produced by Eastern Christianity, including narrative scenes, usually from the Bible or the lives of saints. Icons are most commonly painted on wood panels with egg tempera, but they may also be cast in metal, carved in stone, embroidered on cloth, done in mosaic or fresco work, printed on paper or metal, etc. Comparable images from Western Christianity can be classified as "icons", although "iconic" may also be used to describe a static style of devotional image. In the Greek language, the term for icon painti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 stars appear to be drifting. The celestial sphere is conventionally divided into 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 daytime sky appears blue because air molecules scatter short ...
