Short column:
This column has the ratio of effective length and least lateral dimension less than twelve.
- Short columns fails due to crushing and buckling.
- Rankine-Gordon's formula is used to determine buckling in short and long columns. Euler's formula is used to determine buckling only in long columns.
Long columns:
- This column has the ratio of effective length and least lateral dimension greater than or equal to twelve.
- These columns fail due to buckling.
- Euler's theory is applicable for long columns.
