<p>This Architectural Drawing is section of Column Detailing. A <strong>column</strong> or <strong>pillar</strong> in <a title="Architecture" href="https://en.wikipedia.org/wiki/Architecture">architecture</a> and <a title="Structural engineering" href="https://en.wikipedia.org/wiki/Structural_engineering">structural engineering</a> is a structural element that transmits, through <a title="Compression (physical)" href="https://en.wikipedia.org/wiki/Compression_(physical)">compression</a>, the weight of the structure above to other structural elements below. In other words, a column is a <a title="Compression member" href="https://en.wikipedia.org/wiki/Compression_member">compression member</a>. The term <em>column</em> applies especially to a large round support (the shaft of the column) with a <a title="Capital (architecture)" href="https://en.wikipedia.org/wiki/Capital_(architecture)">capital</a> and a base or <a title="Pedestal" href="https://en.wikipedia.org/wiki/Pedestal">pedestal</a>,<sup id="cite_ref-1"><a href="https://en.wikipedia.org/wiki/Column#cite_note-1">[1]</a></sup> which is made of stone, or appearing to be so. A small wooden or metal support is typically called a post, and supports with a rectangular or other non-round section are usually called <a title="Pier (architecture)" href="https://en.wikipedia.org/wiki/Pier_(architecture)">piers</a>. Generally, concrete columns consist of square, rectangular or circular cross sectional area. Columns are essentially required with the <strong>primary longitudinal reinforcement and lateral ties</strong> to avoid buckling of the primary bars. The distance between two reinforced columns ranges between 3-4 m for small buildings and 6-9 m for sizable facilities where large columns and free spaces are required. For ordinary structures, a distance of 5 m is appropriate, and <strong>the maximum span is 7.5</strong>, while the minimum is 2.5 m. For more details and information download the Drawing file.</p>
