This paper evaluates the effect of Structure-Soil-Structure Interaction (SSSI) between two buildings under seismic excitation given different parameters of the buildings, inter-building spacing, and soil type. An extended simplified reduced-order model, that enables higher mode interaction between structures, is proposed. This enables the exploration of the interaction between buildings with a very large difference in height. A database of strong ground motions records with Far-Field, Near-Field Without Pulse and Near-Field Pulse-Like characteristics are employed. Over 3 million system/ground motion cases are analysed in this extensive parametric study. The results suggest that the extended model captures significant interactions, in displacement responses, for the cases of a small building closely flanked by a much taller one.
