The minimum eccentricity to be considered for an axially loaded RCC column of size 400 mm would depend on the design requirements and the specific code or standards being used.
In general, the eccentricity is the distance between the centroid of the column section and the line of action of the applied axial load. It is important to consider eccentricity in the design of RCC columns as it can lead to additional bending moments and shear forces, which can affect the structural behavior and stability of the column.
The specific minimum eccentricity requirement would depend on factors such as the column slenderness, the type of loading (e.g., concentric or eccentric), and the desired level of safety and performance.
In most design codes, there are guidelines and provisions for determining the minimum eccentricity for various column configurations and loading conditions. These provisions usually consider factors such as the column dimensions, the material properties, and the desired level of safety.
Therefore, without specific design requirements or code references, it is not possible to provide an exact value for the minimum eccentricity for a 400 mm RCC column. It would be necessary to refer to the relevant design code or consult with a structural engineer to determine the appropriate minimum eccentricity for the specific design scenario.

The minimum eccentricity to be considered for an axially loaded RCC co...
As per IS 456: 2000, clause 25.4,
Minimum Eccentricity
All columns shall be designed for minimum eccentricity, equal to the addition of the unsupported length of column divided by 500 and lateral dimensions divided by 30, subject to a minimum of 20 mm.
Where biaxial bending is considered, it is sufficient to ensure that eccentricity exceeds the minimum about one axis at a time.
Calculation:
Unsupported length = 5000 mm
Size of the column = 400 mm
Minimum eccentricity
But, in no case, the minimum eccentricity should be less than 20 mm.
