reinforcement concrete foundation(mass concrete foundation )

foundation tend sto bend , the uper fibres being compressed and the lower fibres being strencthed and put in tension-remedies increase size of base or design as a reinforced concrete foundations.(imposed loads induces tensile stresses in excess of concrete own resistenace)

Size of foundations increased to provide the resistance against the induced tensile stresses -generally not economic due to the extra excavation and material required
(wall or column )


reinforced concrete foundation
strip foudation

1. Consist of continuous strip foundation of mass or reinforced concrete , formes centrally under loadbearing walls.
2. Used to transfer long continuous loads such as walls.
3. THe continouos strip serves as a level base on which the wall is built.
4. THe most economic form of foundation for small buildings on compact soils.
