Abstract
The response of structures in static and dynamic conditions deeply depends on
soil-structure interaction (SSI). 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
