Difference between Long Columns and Short Columns

LONG COLUMN	SHORT COLUMN
The column, whose lateral dimension is very small when compared to its length (or height), is called as long column.	The column, whose lateral dimension is very large when compared to its length (or height), is called as short column.
It is generally fails by buckling.	It generally fails by crushing.
Ratio of effective length to least lateral dimension is greater than 12.	Ratio of effective length to least lateral dimension is less than 12.
Slenderness ratio is greater than 45.	Slenderness ratio is less than 45.
As the height of column increases the load carrying capacity is less.	As the height of column decreases the load carrying capacity is more.
Radius of gyration is less.	Radius of gyration is more.
Load carrying capacity is less.	Load carrying capacity is more.
Long column is subjected to buckling stress	Short column is subjected to compressive stress.
