# Difference Between Short Column and Long Column

## What are the Difference Between Short Column and Long Column?

Most people confuse when asked the difference between long column and short column. peoples interchange the meaning of these two terms. These terms share some similarities but they are very different from each other. The column is the most essential part of any structure. There are different types of columns are used in structure. According to slenderness ratio columns have two types:

### Long Column:

The ratio of length or height of the column to its lateral dimension is greater than 12 is called long column.

(L/b) > 12

Where

L is length or height of the column

b is the lateral dimension

A long column which can fail under load by bending not by crushing and usually the length of column is more than 20 to 30 times of diameter.

### Short Column:

Short columns are the column in which the ratio of length or height to its lateral dimension is less than or equal to 12 is called short column the lateral dimension of short column is large when compared to length.

(L/b) ≤ 12

Where

L is length or height of the column

b is the lateral dimension

The short column which can fail by crushing not by bending which leads to buckling.

### Difference between Long Column and Short Column:

There are a lot of difference between Long column and short column. The difference is given in points below:

 S.No. Short Columns Long Columns 1 The ratio of length or height to its lateral dimension is less than or equal to 12 is known as short column In long column the ratio of length or height of the column to its lateral dimension is greater than 12 is known as long column. 2 short columns can fail because of  their crushing. Long columns can fail because of  their buckling. 3 Short column is not fail by Buckling The radius of gyration of long column is less. 4 The radius of gyration of long column is less. Long column cannot fail by crushing 5 Short columns are subjected to compressive stresses. Long columns are subjected to buckling stresses. 6 In short column the ratio of length to radius of gyration is less than or equal to 40. In long column the ratio of length to radius of gyration is greater than 40. 7 Short column can fail by crushing Long columns can buckle easily or it can fail by buckling. 8 Load carrying capacity in short column is very high as compared to long columns if both columns have same cross sectional area. Load carrying capacity in long column is less as compared to short columns if both columns have same cross sectional area. 9 The load carrying capacity of short column is much more due to its low height. The load carrying capacity of long column is less due to its more height. 10 It is stronger than a long column and short column is highly recommended. It is weaker than a short column and usually, it is not preferred. 11 The lateral dimension of short column is more as compared to the height. The lateral dimension of long column is less as compared to the height. 12 The slenderness ratio short column is less than 45. The slenderness ratio of long column is more than 45.

#### Conclusion:

The main objective of this article “Differences between long column and short column” is that The ratio of length or height to its lateral dimension is less than or equal to 12 is known as short column while in long column the ratio of length or height of the column to its lateral dimension is greater than 12 is known as long column.
