Find The Volume Of Concrete For The Trapezoidal Footing

Find The Volume Of Concrete For The Trapezoidal Footing

In this article, I will discuss how to find the volume of concrete for trapezoidal footing .find the volume of concrete for trapezoidal footing and What is the trapezoidal footing.?

Definition of trapezoidal footing.?

The definition of trapezoidal footing is that footing carries the different/unequal messes from a two-column or pedestal once the heaviest load at the outside the column or pedestal distance is proscribed. This footing is used that areas where the soil is lost,

For example, we have some given data

We will find the concrete volume of trapezoidal footing with the help of the given data.

Trapezoidal footing has two portions one is the rectangle and 2^nd is trapezoidal.

Rectangle portion

Length Of footing  =2.9m

Breath of footing =2.3m

Height of footing = 0.200m

Now find the volume of the footing of the rectangle portion

The volume of the footing of rectangle portion= length x breadth x height

Volume of Footing of rectangle portion= 2.9 x 2.3 x0.200=1.334m3

A trapezoidal portion of the footing

Length of the footing of trapezoidal portion =0.400m

Breath of footing of trapezoidal portion =0.200m

Height of footing of trapezoidal portion =0.400m

Now we find  the volume of the footing of the trapezoidal portion

Calculate the volume of trapezoidal footing with the help of this formula   

V=1/3 {A1 + A2 + (√A1 x A2)H}

Volume of footing of  trapezoidal portion = 1/3 [{A1 + A2 + (√A1 x A2)H}]

Ist we find the area of the footing of the rectangle portion and the area of the footing of the trapezoidal portion

Now we measure the area of both portions of the footing

Area of the footing of rectangle portion = A1

Area of footing of rectangle portion =A1= length x breath

Area of footing of rectangle portion =A1 = 2.9 x  2.3

Area of footing of rectangle portion =A1=6.67m2

Area of footing of trapezoidal portion = A2

Area of footing of trapezoidal portion =A2 = length  x breath

Area of footing of trapezoidal portion =A2 =0.400 x 0.200

Area of footing of trapezoidal portion =A2 = 0.08m2

Now we putt the all value in this formula

Volume of footing of trapezoidal portion  = 1/3 [{A1 + A2 + (√A1 x A2)H}]

Volume of footing of trapezoidal portion  = 1/3 [{6.67+0.08+((√6.67 x 0.08)0.4}]

Volume of footing of trapezoidal portion  = 1/3[(6.67+0.730)0.4]

Volume of footing of trapezoidal portion  = 1/3(2.960)

Volume of footing of trapezoidal portion  =0.987m3

Total volume of concrete of trapezoidal footing is equal

volume of concrete of  trapezoidal footing =  volume of footing of rectangle portion

+volume of footing of trapezoidal portion

Volume The Concrete of  Trapezoidal Footing =  1.334 + 0.987 =2.321m3
