A column is a vertical feature in architecture that is often a rounded shaft with a capital and a base that acts as a support in most circumstances. A column can also be non-structural, serving a decorative purpose or standing alone as a memorial. In classical architecture, columns were used to articulate different parts of a building, such as entrance ways and hallways.
Columns are used to provide structural stability where needed and to present a pleasing appearance where they will be seen by the public. They may also serve a religious purpose by taking on symbolic values. For example, in Christianity, columns are used to articulate churches (especially main entrances), while in Islam they are used to enclose a prayer room (called a mosque).
The word "column" comes from the Latin word columna, which means "stem" or "stalk". Therefore, a column is a slender object that extends upward from a base platform or floor to a capstone or crown. It is usually made of stone or wood, but metal and concrete columns are also found occasionally. The oldest known columns were made of limestone and were built in Egypt around 3000 B.C. These early columns had flat bases and were probably placed within walls as supports for roof beams.
As technology progressed, so did the need for stronger and more stable forms of construction.
Columns are commonly employed to support beams or arches that support the top portions of walls or ceilings. In architecture, a "column" is a structural element with proportional and ornamental characteristics. It provides support for an elevated surface such as a ceiling or roof. In building construction, the term column is also applied to any of several large-diameter cylindrical objects used as supports for heavy materials, especially in interior decorating. The word is also used colloquially for any tall person, object, etc.
The word "column" comes from the Latin word columna, which means "stem" or "stalk." Thus, a column is a slender body supporting at its base so that it cannot be touched without being liable to collapse. The Columner is a kind of column used in architecture and sculpture. It has a circular shaft with four equal branches coming off it.
In mathematics, a column of numbers is a sequence of numerical entries arranged in vertical lines. For example, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100. A column vector is a vector whose components are columns of numbers.
A column is a vertical structural element that is used to convey compressive loads. Columns are often made of compressive-strength materials such as stone, brick, block, concrete, wood, steel, and so forth. The term "column" can also refer to the human body's central supporting bone, known as the columna vertebralis or spinal column.
Columns are used in architecture to provide support for heavy structures such as ceilings and floors. They may be used instead of joists or beams if sufficient space is available to do so. In buildings with load-bearing walls, columns are also required to bear some of the weight of the structure. They may be made of steel or wood, but usually not both in the same house.
The word "column" comes from the Latin word columna, which means "stalk" or "stem". This refers to the appearance of many species of plants, especially flowering plants, such as roses. Flowers commonly have long, slender stalks called petals; inside these petals are more stamens (male organs) than usual leaves (female organs). Because of this configuration, flowers often appear to be surrounded by columns. However, only three of these "stalks" really exist: one main stem with two branches coming off it.
In architecture, a pillar is a strong vertical support feature that stands straight and is often made of a single block of stone, concrete, or bricks. A column is a vertical structural element of a larger structure that acts as a strong foundation. It may be made of wood, steel, or concrete and can be either free-standing or part of a wall or beam.
Pillars are found in many different buildings while columns appear mainly in temples and religious structures. They usually have a flat base with no feet, but some columns have flanges at their bottom to fit into holes in the ground or they may be stood on a base of stones or bricks. The height of a pillar or column is often standardised by law or regulation. For example, in Europe, pillars used as traffic lights must be at least 150 mm high.
