THE SIGNIFICANCE OF STRUCTURE-FOUNDATION INTERACTION

An examination of the importance of structure-foundation-soil interaction with regard to the effect on differential displacement of the column bases, bending moments in the structure and column loads is presented. The structures considered are plane frames with pin-based columns, the foundations considered are strip footings of finite length, and the soil is regarded as being an isotropic homogeneous perfectly elastic continuum of infinite length. The purposes of the paper is to show which factors are most important in controlling the magnitude of interaction effects and to provide graphs of change in differential displacement, bending moment and column load for a range of the most important of these variables. From these results it should be possible to decide when a full interaction analysis needs to be carried out for the structure under consideration, or to decide that interaction effects are of little significance and a complete anlysis can be avoided. /Author/TRRL/
