A column can be defined as a vertical structural member designed to transmit a compressive load. A Column transmits the load from ceiling/roof slab and beam, including its own weight to the foundation.
Types of Columns
Columns can be classified bases on its Shape, Slenderness ratio, type of loading and Pattern of lateral reinforcement.
Classification based on Slenderness ratio
Long Column or Slender:
The length is greater than the critical buckling length and it fails by buckling.
- Short Column : :The length is less than the critical buckling length and it fails by shearing.
- Intermediate Column
Based on shape
- Rectangle
- Square
- Circular
- Polygon
Based on type of loading
- Axially loaded column
- Axial load and non-axial bending column
- Axial load and biaxial bending column
Based on pattern of lateral reinforcement
- Tied columns
- Spiral columns
RCC Columns (Reinforced Concrete Columns)
A reinforced concrete column can be defined as a structural member with a steel frame (reinforcement bars) composed of concrete that is been designed to carry compressive loads.
