Columns or Struts are defined as compression parts with an effective length that exceeds three times the smallest side size.
A structural element that mainly bearing compression forces along the axis is called a compression part.
When compression is subjected to a vertical member, it is called a column, and when it is inclined or horizontal, it is called a strut.
Classifications of Columns on different bases:
Classification of Columns based on Cross Section
- Rectangular Column

- T, L, or + shapes Column
Classification of Columns based on Type of Reinforcement
- Tied Columns
- Spiral Columns
- Composite Columns
Classification of Columns based on Loading
- Axially Loaded Columns
- Eccentrically Loaded Columns: Uniaxial
- Eccentrically Loaded Columns: Biaxial
Classification of Columns based on Slenderness Ratio
- Short Columns
- Long Columns
Classification of Columns based on Construction Materials
- Reinforced Concrete Column
- Steel Column
