Different types of foundations will be selected based on the soil density, bearing capacity to make the structure strong and durable.
However, a small amount of displacement will happen during construction or after the construction of the structure by the load occurrence regardless of the foundation.
Imagine you try to stand on wet soil. After some time, you could see your footprints on the ground. How? Because you applied a force on the soil, which makes it compress and displaced it, making a dent.
The same applies to buildings. A vertical displacement that happens on the structure when the load occurs is called settlement of the foundation. The foundation settlement is measured in mm.
The foundation settlements have been classified as below.
The total vertical displacement (the combination of all settlement) happens at the foundation due to load occurrence is called a total settlement of the foundation.
The specification and calculation of foundation settlement have been mentioned in IS code 8009 Part 1 and Part 2.
It is classified as,
The structure may settle down due to the following reasons,
The foundation settlement for different construction works has been mentioned below.
