How to work out Volume of Trapezoidal Footing at construction site

This construction video from learning technology will teach you in detail how to estimate the volume of Trapezoidal Footing at construction jobsite.

If there are two columns and one of the column contains a much greater load (necessitating a broader foundation for secure bearing), then a trapezoidal shaped foundation is mostly suitable.

The trapezoidal footing is applied in an exceptional case. It may be utilized under the situation where it is required to bear unequal loads associated with two columns if the distance outside the column of the massive load is restricted.

Under this condition applying a rectangular footing may cause that the consequential of loads does not fall at the middle length of the footing.

To resolve this issue, a trapezoidal footing is utilized in an effective manner that the center of gravity of the footing is situated under the resultant of the loads. Similarly, the distribution of contact pressure will be identical.

To get the complete process, go through the following tutorial.
