A steel column is extended by welding or bolting splice plates on the flanges and webs or walls of the columns to provide a few inches or feet of load transfer from the upper to the lower column section. A timber column is usually extended by the use of a steel tube or wrapped-around sheet-metal plate bolted onto the two connecting timber sections.
In Roman and post-Renaissance work, the entablature may be carried from column to column in the form of an arch that springs from the column that bears its weight, retaining its divisions and sculptural enrichment, if any. There are names for all the many parts of the orders.

[citation needed] Ionic columns are most often fluted. After a little early experimentation, the number ...
In Australia, these steel sections are commonly referred to as Universal Beams (UB) or Columns (UC). The designation for each is given as the approximate height of the beam, the type (beam or column) and then the unit metre rate (e.g., a 460UB67.1 is an approximately 460 mm (18.1 in) deep universal beam that weighs 67.1 kg/m (135 lb/yd)).

In their original Greek version, Doric columns stood directly on the flat pavement (the stylobate) of a temple without a base. With a height only four to eight times their diameter, the columns were the most squat of all the classical orders; their vertical shafts were fluted with 20 parallel concave grooves, each rising to a sharp edge called an arris.
The orders, structural systems for organising component parts, played a crucial role in the Greeks' search for perfection of ratio and proportion. The Greeks and Romans distinguished three classical orders of architecture, the Doric, Ionic, and Corinthian orders; each had different types of capitals atop the columns of their hypostyle and ...
The form with the f-block included in the main body is sometimes called the 32-column [6] or long form; [33] the form with the f-block cut out the 18-column [6] or medium-long form. [33] The 32-column form has the advantage of showing all elements in their correct sequence, but it has the disadvantage of requiring more space. [34]
