# Short column and Long column- Difference by the Slenderness ratio

A compression member i.e. column is an important element of every reinforced concrete structure. These are used to transmit the load of superstructure to the foundation safely.

A column is a vertical compression member which is mainly subjected to axial loads and the effective length of which exceeds three times its lateral dimension.

## Types of column

1. Short Column
2. Long Column

## What is slenderness ratio?

The slenderness ratio is the ratio of the effective length of the column to the least lateral dimension of the column.

## Short column

The column is considered as short column when the slenderness ratio of column i.e. ratio of effective length to its least dimension,

Lex = Effective length of column in minor axis

Ley = Effective length of column in minor axis

d = Depth of column in respective axis b = Breadth of column

## Long column

The column is considered as long column when the slenderness ratio of column is greater than 12.

Lex = Effective length of column in minor axis

Ley = Effective length of column in minor axis

d = Depth of column in respective axis
