Why always the number of steel bar are in even number?
Not in odd number like 5 bars 7 bars.
While we can but the extra bars in the tension zone.

India 4 & 5 bars used the column spacing can more than 300 mm so the column concrete will be out side in column. Next the strength will be reduce.

@Arun.
Max diameter used in longitudinal bars depends upon size of the beam.

Min. 4 bars in rectangular/square column and min. 6 bars in circular shape column.
The bar shall not be less than 12mm. The nominal cover shall any case not be less than 40mm.
In our site they provided 40mm cover. Min. Distance b/w individual bars -the dia of larger bar -5mm more.
Nominal max. Size of coarse aggregate.

But In case of circular column, why only 6 nos of bars provided? Why not 4 or 5? Can anyone clarify?

In column there is a buckling moment due to the up coming load so at each corner there should be a longitudinal main steel bar is provided.
