How to Calculate the Concrete Quantity of a Trapezoidal Footing? | Trapezoidal Footing Excel sheet

Our team explained the Calculate the Concrete Quantity of a Trapezoidal Footing process step-by-step (with a diagram) using this simple trapezoidal formula and an easy-to-use excel sheet calculator.

What is a Trapezoidal Formula?

Volume of Trapezoidal = h/3 x (A1 + A2 + √ (A1 x A2))

 

 

where,

Height of Trapezoidal h = “H”

The bottom area of Trapezoidal A1 = Length “A” x Breadth “B”

The top area of Trapezoidal A2 = Length “a” x Breadth “b”

 

“Refer the diagram below diagram”


Trapezoidal Footing Excel sheet



How to Find Volume of Trapezoidal Footing concrete?

Volume of Trapezoidal Footing Formula = F1 volume+ F2 volume

Where,

F1 = Base Footing area | F2 = Trapezoidal Area of Footing

Length “A” = Bottom Footing Length of X-direction. | Length “B” = Bottom Footing Length of Y-direction.

Length “a” = Top Footing Length of X-direction. | Length “b” = Top Footing Length of Y-direction.

H1 = Height of Bottom Footing. | H2 = Height of Trapezoidal Footing.

F1 volume = Length “A” x Breadth “B” x Height H1

F1 volume = 1.2m x 1.2m x 0.300m = 0.432 cum

 

F2 volume = H2/3 x (A1 + A2 + √ (A1 x A2))

A1 (Bottom area of Trapezoidal) = Length “A” x Breadth “B”

A1 (Bottom area of Trapezoidal) = 1.2 x 1.2 = 1.44 sqm

A2 (Top area of Trapezoidal) = Length “a” x Breadth “b”

A2 (Top area of Trapezoidal) = 0.6 x 0.6 = 0.36 sqm

 

F2 volume = 0.3/3 x (1.44 + 0.36 + √(1.44 x 0.36))

F2 volume = 0.1 x (1.44 + 0.36 + 0.72) = 0.252 cum

 

Volume of Trapezoidal Footing Formula = 0.432 + 0.252 = 0.684 cum

 

Our team have also created a simple excel sheet calculator tool. Make use of it.
