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

__Given data:__

Length at the base = L = 750mm.

Breadth at the base = B = 600mm.

Total height H = 500 mm.

Top surface length = l = 450mm.

Top surface width = b = 300mm.

**Calculation:**

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**.

The volume of the RCC footing is calculated in a separate article as linked below.

**The self-weight of RCC footing**

= [ 2500 kg/m³ × 0.1904m³]

= **476kg.**

Let us now calculate the self-weight or dead load of the **plinth beam** as shown in the drawing.

__Given data:__

The span of plinth beam-1 (PB1) = 4500mm.=4.5m.

The span of plinth beam-2 (PB2) = 3000mm.=3.0m.

Sectional dimension of plinth beams = 230mm. × 450mm.

= 0.23m. × 0.45m.

**Calculation:**

**The self-weight of the PB2**

= [Unit weight × (volume)]

= [ 2500 kg/m³ × (3m × 0.23m. × 0.45m.)]

= **776.25kg.**

** The self-weight of the PB1**

= [Unit weight × (volume)]

= [ 2500 kg/m³ × (4.5m × 0.23m. × 0.45m.)]

= **1164.38kg.**

Thank you for going through these calculation steps❤. Have a good day ðŸ˜„.
