How To Calculate The Self Weight Of Column & Beam
Hello Guys in this topic we know about how to calculate self weight of column. In structural building designing by civil engineer it is considered that how much load is applied on column and distribute in footing and in soil by Foundation footing and column.
There is various types of load acting on RCC Column. Calculating the load applied on RCC column in structural designing and construction size of footing, size of column and size of beam will be decided according to strength capacity
Various types of load acting on column
1) Self weight of column
2) Self weight of beam per meter running length
3) Weight of slab per sq. meter
4) Brick wall per meter running length
Weight of slab is total calculation of Dead load of slab floor finishing load and live load

How to calculate self weight of column
Calculation : height of column = 3 m
Assume Size of column = 9″×9″
Inch into mm = 230mm× 230mm
For calculating self load for column we have require self weight of concrete that is 2500 kg/m3 for RCC and self weight of Steel that is approx. 8000 kg/m3
Self weight of column is equal to weight of concrete in column and weight of Steel which is used in construction of column. First we calculate weight of concrete in column.
A) weight of concrete used in column
Size of column = 230mm×230mm
Height of column=3m
Volume of concrete = 0.23m×0.23m×3m
Volume of concrete= 0.1587 m3
Weight of concrete = volume × density
Weight of concrete =0.1587 m3×2500kg/m3
Weight of concrete = 396.75 kg
We should convert in kilo Newton we get load applied by concrete in column is about 3.96 kN

B) now calculate weight of Steel used in column by Thumb Rule we know that approx. 1% of concrete steel is used in column
Density of steel = 8000kg/m3
Volume of steel is 1% of concrete
Weight of steel = 0.01×0.1587m3×8000kg/m3
Weight of steel = 12.7 kg
Now convert kilo per meter into kilo Newton so load applied by Steel in column is approx. 0.127kN
Now total weight of column is equal to weight of concrete and weight of Steel
Total weight = 396.75 kg+12.7kg
Total weight = 409.446 kg
Now total self load of column is about 4.09 k.N acting on column
Hence total self load of column is about 4.09 kilo Newton per floor.
