Trapezoidal Footing Calculator | Trapezoidal Formula

How To Work With Trapezoidal Footing Calculator?

Important Point

In this calculator, we calculate the trapezoidal footing area. As per the below process work with calculator.

Step – 1.

Fill Footing area Length and Breadth as per below picture shown.

In this footing Bottom (base) area and Top area are different so carefully check in above image.

Here, As per the below image Bottom area Length A and Breadth B Fill in box

And As per the below image Top area Length a and Breadth b Fill in box

Step – 2.

Fill Footing area Height in box as per shown in below picture

In this footing Bottom (base) height and Top height are different so carefully check in above image.

Here, As per the below picture shown fill Footing Bottom(Base) Height H1 in box.

As per the below picture shown fill Footing Top Height H2 in box.

Step – 3.

As per the below picture shown your answer given in box.

Volume of Trapezoidal =

h/3 * ( A1 + A2 + √ (A1 x A2 ))

Length

Here,

A1 (Bottom area of Trapezoidal) = Length A * Breadth B

A2 (Top area of Trapezoidal) = Length a * Breadth b

h Height of Trapezoidal = H

Trapezoidal Footing Formula = F1 Area + F2 Area

F1 Area = Length A * Breadth B * Height H1

F2 Area = H2/3 * ( A1 + A2 + √ (A1 * A2 ))

A1 (Bottom area of Trapezoidal) = Length A * Breadth B

A2 (Top area of Trapezoidal) = Length a * Breadth b

Here,

F1 = Base Footing area

F2 = Traprzoidal 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 Terpziodal Footing.
