# Difference Between Short Column and Long Column

• There are many differences between the Short column and the Long column, some of which are given below.
• A short column is a column whose ratio of its actual or effective length and its minimum lateral dimension is less than or equal to 12. A column with such features is called a short column.
• The formula by which a short column can be calculated is ( lef / b ) <= 12 . Where lef = Effective Length of a column, b = Least lateral dimension of a column.
• If the average working length and minimum lateral size are less than or equal to 12, then it is called a short column.
• In the case of the short column, the effective length to a minimum radius of gyration ratio is less than or equal to 40.
• In the case of the short column, the buckling tendency is very low as compared to the long columns.
• In the case of the short column, the crushing tendency is very high as compared to the long columns.
• In the case of a short column, the load-carrying capacity is higher as compared to the long columns of the same cross-sectional area.
• In the case of a short column, the failure is due to their crushing.
• In the case of a short column, the radius of gyration is more as compared to the long columns.
• The short column has the capacity to carry a large load due to its low height as compared to the long columns.
• The short columns are under great pressure and compressive stress.
• In the case of the short column, the slenderness ratio is less than 45.
• In the case of the short column, the columns have a larger lateral dimension as compared to their height.
• The short column is much stronger than the longer column and is highly recommended.
• Long or thin is the column whose ratio of its actual or effective length and its minimum lateral dimension is not less than 12. A column with such features is called the long column.
• In long columns, the allowable values of pressure or stress in concrete and steel, which are used for small columns, should be multiplied by the coefficient Cr given by the following formula.
• Cr = 1.25 – lef / 48 b , where Cr = Reduction Coefficient, Where lef = Effective Length of a column, b = Least lateral dimension of a column.
• If the average working length and minimum lateral size are greater than 12, then it is called a long column.
• In the case of the long column, the effective length to a minimum radius of gyration ratio is greater than 40.
• In the case of the long column, the Long and cylindrical pillars are easy to buckle down as compared to the short columns.
• In the case of the long column, the crushing tendency is very low as compared to the short columns.
• The load-bearing capacity of a long column is less than that of a short column of a similar cross-sectional area.
• In a civil structure, all long columns fail due to their buckling.
• In the case of the long column, the radius of gyration is less as compared to the short columns.
• The long column has the capacity to carry less load due to its high height as compared to the short columns.
• Long columns are subject to buckling pressure or stress.
• In the case of the long column, the slenderness ratio is more than 45.
• In the case of the long column, the columns have a smaller lateral dimension as compared to their height.
• The long column is much weaker than the short column and is usually not preferred.
