### How to calculate the total load over the RCC slab?/Calculating the factored load of a RCC slab.

Let us calculate the total load over the RCC slab as shown below.

Given data:

Length of slab = 4500mm.=4.5m.

Width of slab = 3000mm. = 3.0m.

Slab thickness = 125mm. = 0.125m.

Calculation:

Where,

= [self wt. of slab + floor finish]

a. Self wt. of slab

= [(volume of the slab) x density]

= [(length x breadth x thickness) x 25KN/m³]

= [( 4.5m. x 3.0m. x 0.125m.) x 25KN/m³]

= [1.6875m³  x 25KN/m³]

= 42.19KN.

b. Total load of floor finish

= [area of slab x wt. of floor finish /m².]

= [ (length x breadth)  x 1.5KN/m²]

= [(4.5m. x 3.0m.) x 1.5KN/m²]

= [13.5m² x 1.5KN/m²]

= 20.25KN.

= [self wt. of slab + floor finish]

= [42.19KN + 20.25KN]

= 62.44KN.

2. Total live load over the slab

= [area of slab x live load /m².]

=  [ (length x breadth)  x 4KN/m²]

= [(4.5m. x 3.0m.) x 4KN/m²]

= [13.5m² x 4KN/m²]

= 54KN.

= [62.44 + 54]

= 116.44 KN

Total load over the slab in kg.

= [116.44 KN x 101.97]

= 11,873.39 kg.

Wu = [1.5 x total load]

= [1.5 x 116.44]

Wu = 174.66 KN.

Factored load of RCC slab per unit area

W = [ total factored load ÷ area of slab]

= [ 174.66  ÷ (4.5 x 3)]

W = 12.94KN/m²

Thank you for going through these calculation steps. Have a good day 😄.
