Minimum depth of foundation for the load bearing wall of a building is restricted to
Answers
The Building has two main components, one is constructed above the ground level is known as super-structure while another is constructed below the ground level is called sub-structure. Foundation system falls into the category of sub-structure. The foundation is the part of a building that transfers the load of the structure to the ground. The foundation transfers the load of structure in such a manner so that the soil below the footing never undergoes excessive settlement. To resist the excessive settlement, the footing should be designed considering the factors like type of building, type of soil, the minimum depth of foundation, site topography, etc. The groundwater level, underground water courses, old drains, pits, wells, the old foundation, etc, and presence of excessive sulphates or other injurious compounds in the groundwater and soil should also be considered at the time of footing design.
The minimum depth of foundation is the most important factor which affects the stability of footings. Hence the foundation should be located at a minimum depth, that the footing gets maximum stability and it can easily transfer the load of the structure to the ground.
