WHAT IS FOUNDATION IN BUILDING CONSTRUCTION
Foundation is the part of wall pierce or column in direct contact with the soil which transmits load from the structure to the soil. It is sometimes referred to as Artificial foundation on the ground on which it bears as natural foundation.
The primary functional requirements of foundation is strength and stability.
The combined dead load, imposed load and wind load on the building must be safely transmitted to the soil without causing any form of deflection or deformation of the building or movements of the drum that would impair the stability of the building structure.
Foundation in construction can generally be classified into two, namely Shallow Foundation and Deep Foundation.
Shallow Foundation transfers the load to a stratum present in a shallow depth. While the deep foundation transfers the load to a deeper depth below the ground surface.
High-rise building like a skyscraper or a building constructed on very weak soil requires deep foundation. If the constructed building has the plan to extend vertically in future, then a deep foundation must be recommended.
FUNCTIONS OF FOUNDATION IN BUILDING CONSTRUCTION
- It provides a firm and level base capable of carrying the superstructure without any distortion.
- It Provides overall lateral stability for the structure.
- Load Distribution is carried out evenly.
- The load intensity is reduced to be within the safe bearing capacity of the soil.
- The soil movement effect is resisted and prevented.
- Scouring and the undermining issues are solved by the construction of foundation.
REQUIREMENTS OF FOUNDATION IN CONSTRUCTION
The foundation must possess the following requirements :
- It must not twist or break under load.
- It must not disintegrate in the presence of water.
- It must not crack because the soil is not firm.
- It must transmit the dead and the imposed loads to the soil.
- The location of the foundation must not be affected or influenced by future works or factors.
- The foundation should be designed and constructed to resist any movement of the subsoil
