A two-dimensional, structure–soil–structure interaction, formulation using simple discrete models for structures and soil, and including a rotational spring as a key buildings interaction mechanism is proposed. An inverse cubed power law is proposed for this rotational interaction spring. This relationship is obtained by equating energies from the low order discrete and high order Finite Element models. By employing simplifying assumptions, the dynamic problem is conveniently reduced to a meaningful set of four parameters. Insight into the influence of the geometrical characteristics of the structures, distance between them and soil type on the dynamic structure–soil–structure interaction effects is closely examined.
