ResumoA foundation is here modelled as long plate of variable thickness placed underneath the base of a long thin wall and resting on the surface of the underlying medium. The foundation distributes the vertical load due to the wall over the relatively soft substrate. The design of the foundation traditionally relies upon empirical or semi-empirical criteria. An analysis of these criteria using optimisation theory reveals that they probably depend upon the principles of minimum stress acting on the foundation's lower edge and of maximum permitted height of the bulb of foundation.
