The foundation of a building is that part of walls, piers and columns in
direct contact with, and transmitting loads to, the ground. The building
foundation is sometimes referred to as the artificial foundation, and the ground
on which it bears as the natural foundation. Early buildings were founded on
rock or firm ground. It was not until the beginning of the twentieth century
that concrete was used as a foundation base for walls. The primary functional
requirement of a foundation is strength and stability.
The combined, dead, imposed and wind loads on a building must be
transmitted to the ground safely, without causing deflection or deformation
of the building or movement of the ground that would impair the stability of
the building or neighboring structures. Foundations should also be designed
and constructed to resist any movement of the subsoil.
Foundations should be designed so that any settlement is both limited and
uniform under the whole of the building. Some settlement of a building on a
soil foundation is inevitable. As the building is erected the loads placed on
the foundation increase and the soil is compressed. This settlement should be
limited to avoid damage to service pipes and drains connected to the building.
Bearing capacities for various rocks and soils are assumed and these capacities
should not be exceeded in the design of the foundation to limit settlement.
There are a number of approaches to foundation construction, from strip
foundations, piles and rafts, all of which are constructed of concrete
