    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.
