The soil-structure interaction can be analysed by means of the soil stiffness functions. The classic stiffness approach comes from elastic analysis and does not take into account soil nonlinearity. This paper deals with the effects of soil nonlinearity in the formulation of new stiffness functions for a shear wall with a shallow foundation. This type of structure can be used for strengthening at low cost buildings against earthquakes. The analysis of the whole soil, foundation and shear wall system behaviour in static and pseudostatic conditions is carried out by means o
