A general analysis is presented for the settlement of a structural foundation in which the structure, foundation and soil are treated as a single system. For pad, pile and raft foundations, a brief review is made of some elastic solutions for settlement behaviour which are required for the complete structure-foundation interaction analysis. For a simple two-dimensional frame, a series of solutions are presented to show the effect on the settlement and differential settlement of such factors are the type of foundation, the consideration of interaction between footings, the consideration of horizontal as well as vertical movements and the number of storeys in the frame. In general, the stiffness of the structure tends to reduce differential settlements, and hence economics in foundation design may be effected by taking structural stiffness into account. For cases in which the structure is relatively flexible, a simple equal settlement criterion is described for pad footings. This criterion leads to larger footings than the usual equal pressure criterion but results in greatly decreased differential settlements. /Author/TRRL/
