How to design a column in Excel

RCC Column: A column plays a vital role in a structure. It is acts like the legs on which a structure rests on. It is specifically developed to withstand axial and lateral forces and transmit them to the footings in the ground.

Columns provide support to the floors in a structure. Slabs and beams deliver the stresses to the columns. So, it is necessary to design durable columns.

A column is categorized on the basis of the following factors:

1. On the basis of shape - Rectangle, Square, Circular, Polygon

2. On the basis of slenderness ratio:

The ratio of the actual length of a column to the lowest radius of gyration of its cross section is known as the slenderness ratio - Short RCC column, =< 10, Long RCC column, > 10, Short Steel column, =<50, Intermediate Steel column, >50 & <200, Long Steel column, >200

3. Dependent on the type of loading:

Axially loaded column - A column dependent on axial load and unaxial bending, A column dependent on axial load and biaxial bending
