COLUMN LOAD CALCULATION
same method of beam load calculation
Unit weight of steel = 7850kg /m^3 consider as 8000kg /m^3
Unit weight of concrete=2440kg /m^3
consider as 2500kg /m^3
Total volume of the concrete 1.5% of the steel in column
The column area consider 250mm X 450mm with 2 metre height
Volume of column= 0.25mm X0.46mm X 2
=0.23m^3
Concrete weight = unit weight X volume of column
=2500 X 0.23
=575kg/m^3
Steel weight = 2% of steel X unit weight of steel X volume of area
= 2÷100 X 8000 X. 23
= 36.8kg/m^3
Total self weight
of column = steel weight + concrete weight
= 575 kg/m^3 + 36.8 kg/m^3
=611.8 kg/m^3
=6.118KN /m^3
