### 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.
