There are different types of columns used in structures. In our previous article, we have already discussed that topic. In this article, I will discuss, the difference between short column and long column.
What is Short Column?
When the ratio of the effective length of a column to its least lateral dimension does not exceed 12, it is called short column.
What is long column?
When the ratio of the effective length of a column to its least lateral dimension exceeds 12, it is called long column.
Difference Between Short Column And Long Column:
| Short Column | Long Column |
| 1. The ratio of the effective length to its least lateral dimension is less than 12. | 1. The ratio of the effective length to its least lateral dimension is greater than 12. |
| 2. The slenderness of short column is less than 45. | 2. The slenderness of long column is greater than 45. |
| 3. Less radius of gyration. | 3. Greater radius of gyration. |
| 4. The load-carrying capacity of short column is greater than long column. | 4. The load-carrying capacity is less compared to short column of same cross-sectional area. |
| 5. Stronger than long column and highly preferrable. | 5. Weaker than short column and generally not preferred. |
| 6. Short column is subjected to compressive stress. | 6. Long column is subjected to buckling stress. |
| 7. Mechanical failure mainly occurs due to shearing. | 7. Long columns are liable to fail due to buckling. |
