Meaning of COLUMN in English

In architecture, a vertical element, usually a slender shaft, that provides structural support by carrying axial loads in compression; columns are also subject to buckling.

Columns may be exposed or hidden in walls; constructed of precast concrete, masonry, stone, or wood or of steel wide-flange, pipe, or tubular sections; they may be plain, fluted, or sculpted, with or without a capital and base. Columns may also be nonstructural, used for decorative or monumental purposes. See also intercolumniation , order .
