Slenderness Ratio in Columns

Slenderness ratio is an important factor to consider while designing columns in a building. It is the ratio of effective length of the column to its least radius of gyration. When the slenderness ratio lies between 32 to 120, the column is known as a medium column. Let's understand this in detail.

What is a Column?

In a building, columns are vertical structural members that are used to support the weight of the structure above it. They are designed to withstand compressive loads and are an essential part of the building's structural system.

What is Slenderness Ratio?

Slenderness ratio is the ratio of the effective length of the column to its least radius of gyration. It is an important factor to consider while designing columns as it determines the stability of the column under compressive loads.

Types of Columns Based on Slenderness Ratio

Based on the slenderness ratio, columns can be classified into the following types:

1. Short Columns - When the slenderness ratio is less than 12, the column is considered a short column. These columns are designed to withstand compressive loads without buckling.

2. Long Columns - When the slenderness ratio is greater than 120, the column is considered a long column. These columns are designed to withstand compressive loads and also to resist buckling.

3. Medium Columns - When the slenderness ratio is between 32 to 120, the column is considered a medium column. These columns are designed to withstand compressive loads and are less prone to buckling than long columns.

Conclusion

The slenderness ratio is an important factor to consider while designing columns in a building. When the slenderness ratio lies between 32 to 120, the column is known as a medium column. These columns are designed to withstand compressive loads and are less prone to buckling than long columns.
