Introduction
A columns/pillar is something that can be termed as an architectural member as well as a structural member. When it is termed as a structural member then it implies that the column is working as a compression member and is transferring loads whereas when we talk about being an architectural member, we are talking about columns that exist for aesthetic needs. The ancient Egyptian architecture used columns back in 2600 BC when Imhotep used stone columns for buildings
How Does A Column Work?
A column works by transferring the load that is being applied to its top to the bottom. It is by essence a compression member and usually transfers the load to the foundation/ground. The column is designed while keeping in mind the slenderness ratio and the moments that it will be subjected to.
Types of Column
- Doric order
- Tuscan order
- Ionic order
- Corinthian order
- Composite order
- Solomonic
Applications of Column
- Vertical Compression Member
- Aesthetics
- Load Bearing
- To Transfer load from top to bottom
- Architectural
- Structural (buildings, frame structures)
Precautionary Measures 
- Slender Ratio should be kept in mind.
- Columns shouldn’t buckle.
- No column should be loaded with more weight than it has been designed to carry.
- Any sort of cracks should be attended to right away.
- Jacketing should be carried out to reinforce a weak column.
