A column is a vertical structural member that functions as a type of strut.
Understanding Struts
According to structural definitions, a strut is a structural member that is subjected to an axial compressive force. This means the forces acting on the strut are pushing inward along its length.
Based on the definition provided:
- "A structural member, subjected to an axial compressive force, is called a strut."
- Struts can be found in various orientations: "As per definition, a strut may be horizontal, inclined or even vertical."
Struts are fundamental components in many structures, used to brace against forces that would otherwise cause instability or collapse.
What is a Column?
While a strut can have any orientation, a column is a specific type of strut based on its direction and use.
As the definition clarifies:
- "But a vertical strut, used in buildings or frames, is called a column."
Therefore, a column is simply a vertical strut typically found in buildings, frames, and similar structures. The term "column strut" isn't a distinct classification but rather describes a column in terms of its function as a vertical compression member (a strut).
Key Characteristics
Here's a summary of the relationship and characteristics:
- Strut: A structural member under axial compression. Can be horizontal, inclined, or vertical.
- Column: A vertical structural member under axial compression. Essentially, a column is a vertical strut used in specific contexts like buildings and frames.
- Function: Both resist compressive loads.
- Orientation: This is the key difference distinguishing a column from other types of struts.
In essence, when you see a vertical support member in a building that is primarily carrying downward weight, it is acting as a column, which is by definition a vertical strut.
