Skyscraper
A skyscraper is a tall continuously habitable building having multiple floors. Most modern sources define skyscrapers as being at least or in height, though there is no universally accepted definition, other than being very tall high-rise buildings. Skyscrapers may host offices, hotels, residential spaces, and retail spaces. One common feature of skyscrapers is having a steel frame that supports curtain walls. These curtain walls either bear on the framework below or are suspended from the framework above, rather than resting on load-bearing walls of conventional construction. Some early skyscrapers have a steel frame that enables the construction of load-bearing walls taller than those made of reinforced concrete. Modern skyscraper walls are not load-bearing, and most skyscrapers are characterized by large surface areas of windows made possible by steel frames and curtain walls. However, skyscrapers can have curtain walls that mimic conventional walls with a small surfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Storey
A storey (English in the Commonwealth of Nations, Commonwealth English) or story (American English), is any level part of a building with a floor that could be used by people (for living, work, storage, recreation, etc.). Plurals for the word are ''storeys'' (UK, CAN) and ''stories'' (US). The terms ''floor'', ''level'', or ''deck'' are used in similar ways as storey (e.g., "the 16th ''floor''"). However, when referring to an entire building, it is more usual to use storey or story (e.g., "a 16-''storey'' building"). The floor at ground or street level is called the ''ground floor'' (i.e. it needs no number); the floor below ground is called ''basement'', and the floor above ground is called "first" in many regions. However, in some regions, like the US, ''ground floor'' is synonymous with ''first floor'', leading to differing numberings of floors, depending on region – even between different national varieties of English. The words ''storey'' and ''floor'' normally exclud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
