How to calculate the self weight of RCC slab, beam, & column?/ How to find the self-weight of RCC structures?/Dead load of RCC structures.

 Let us now calculate the self-weight or dead load of the RCC structures as shown in the drawing.




Given data:

RCC slab

Length = 4m ( Ls ) 

Width = 3.3m ( Ws )

Thickness = 125mm =0.125m. (Ts )


RCC beam

Length = 4m ( Lb )

Width = 230mm = 0.23m. (Wb )

Depth = 450mm = 0.45m. ( Db )


RCC column

Height = 2.7m. (Hc )

Width = 230mm = 0.23m ( Wc )

Length = 450mm = 0.45m. ( Lc )


The self-weight of any RCC structure is calculated by the formula

  = [Unit weight × volume.]

As you know, the unit weight of the RCC structure = D =2500kg/cum.

1. Self-weight of the slab

Wt. of the slab

     = [unit weight× volume of the slab]

     = [ D × ( Ls × Ws × Ts )]

     = [ 2500kg/cum. × ( 4m. × 3.3m. × 0.125m. )]

     = [ 2500kg/cum. × 1.65cum.]

     = 4125kg.


2. Self-weight of the beam

Wt. of the beam

    = [unit weight × volume of the beam]

    = [ D × ( Lb × Wb × Db )]

    = [ 2500kg/cum. × ( 4m. × 0.23m. × 0.45m. )]

    = [ 2500kg/cum. × 0.414cum.]

    = 1035kg.


3.  Self-weight of the column

Wt. of the column

   = [unit weight × volume of the column]

   = [ D × ( Hc × Wc × Lc )]

   = [ 2500kg/cum. × ( 2.7m. × 0.23m. × 0.45m. )]

   = [ 2500kg/cum. × 0.279cum.]

   = 698.63kg.
