FUNCTIONS OF FOUNDATION
FUNCTIONS OF FOUNDATION
The functions of foundation are:
1. To distribute the weight of the structure over a large area so as to avoid exceeding load bearing capacity of the soil. Masonry walls R.C.C. or steel columns can carry considerable load per unit area where as soil can carry quite less load per unit area. Hence there is need to gradually increase the area for load transfer and finally provide sufficient area. This is the main purpose of foundation.
2. Incidentally by providing foundation load on soil is evenly distributed and hence unequal settlement of parts of superstructure prevented.
3. Foundation takes the structure deep into the ground and anchors it. The overturning and sliding of structures is prevented.Thus foundation gives stability to the structure.
4. Foundation provides a level surface for building operations.
