load carrying capacity of column
Here, we have uploaded the excel sheet to calculate load carrying capacity of different column sizes, you can also calculate the column load(different column sizes) by using the excel
Pu = 0.4fck.Ac + 0.67fy.Asc
as per IS code 456 2000
Where
Pu = ultimate axial load carrying capacity of the column
fck = characteristics of the comprehensive strength of concrete which is given
Ac = area of concrete in the column which will be calculated
Asc = area of Steel in the column which will be calculated

EXAMPLE
1.The load carrying capacity of a column designed by working stress method is 500 kN. The ultimate load of the column is 750 kN
Permissible stresses in steel structure member:
S.No. | Types of stress | Permissible stress (MPa) | Factor of safety |
1 | Axial Tensile stress | 0.6 fy | 1.67 |
2 | Maximum axial compressive stress | 0.6 fy | 1.67 |
3 | Bending tensile stress | 0.66 fy | 1.515 |
4 | Maximum bending compressive stress | 0.66 fy | 1.515 |
5 | Average shear stress | 0.4 fy | 2.5 |
6 | Maximum shear stress | 0.45 fy | 2022 |
7 | Bearing stress | 0.75 fy | 1.33 |
8 | Stress in slab base | 185 | - |
