Classification of Columns

Columns are vertical structural members that transfer the load from the slabs and beams to the foundations

Columns are mainly subjected to axial compression forces. So it is the compression members of the structure.

When a compression member is vertical and its effective length (height) exceeds three times its least lateral dimension, It is called Column.

When the compression member is horizontal or inclined, it is called Strut. Struts are usually found in concrete trusses.

A short compression member, with a height less than three times its least lateral dimension, is called a pedestal or a stub column. Pedestals are placed at the base of columns to transfer a load of columns to a footing, pile cap, or mat foundation.
