Columns are vertical structural elements where the load is transferred parallel to the longitudinal axis as compression, and sometimes as tension . For example, think of a rectangular table with four legs at the corners. The weight of the table and all the objects on the table is transferred to the floor through the legs acting in compression.

Columns with biaxial loading is common in corner columns with beams rigidly connected at right angles at the top of columns.

What are the three columns in Greek architecture?
Greek columns are classified in three different styles, or orders. These orders include Doric, Ionic, and Corinthian. These orders were adopted by the Romans, and this adoption took place in the 1st century BC. Today, these three orders are still used in architecture around the world, especially in European culture. The Doric and Ionic orders were said to have originated around the same time. Ionic order was established in eastern Greece, while the Doric started the west and mainland. Many say that these two orders originated as wooden structures. And soon after 600 BC, the Doric order seemed to have spread across Greece and into Sicily. It’s also important to note that early Greeks were well aware of the use of stone columns in Ancient Egyptian architecture, but these were mostly used in the interior of buildings. In Greece, these stone columns were primarily used as a dominant feature in exteriors.

Why are columns important?
Columns are still used widely today for many different purposes. While many of these are less decorative and less meaningful than they were centuries and millennia ago, columns are still an important part of architecture today. But while many of the same styles and forms are used in contemporary columns, builders have introduced new materials to make these columns larger, stronger, and more effective at holding weight for long periods of time. Steel, iron, and concrete are some of the more popular materials that have been added to the construction of columns since the Greek and Roman periods The addition of these materials have made buildings stronger than ever before. The brute strength of steel allows builders to create large structures and extremely heavy buildings. Columns will continue to get more sophisticated and strong as time goes by, so humans should expect to see more advanced types of columns introduced in the decades to come.
Where did the Doric and Ionic order originate?
The Doric and Ionic orders were said to have originated around the same time as one another. The Ionic order was established in eastern Greece, while the Doric started in the west and mainland of modern-day Greece.

It’s important to note that the early Greeks were well aware of the use of stone columns in ancient Egyptian architecture. However, in ancient Egypt, columns were mostly used in the interior of buildings. In Greece, these stone columns were primarily used as the dominant feature in exterior structures. This made them exterior columns.

Over the centuries, a variety of column types and column designs have evolved, including in Egypt and Persia. To see different styles of columns, browse our Photo Gui…
Function of A Column
- Columns are historically functional. Today a column can be both decorative and functional. Structurally, columns are considered compression members subject to axial compressive forces — they allow space to be created by carrying the load of the building. How much load that can be carried before "buckling" depends on the column's length, diameter, and construction material. T…
Columns and Your House
