This study presents an investigation of the dynamic interactions between a surface structure lying on two different
soil deposits and a square-shaped buried structure embedded in the soil. To this end, a large number of numerical models are
generated by using a well-known Finite Element Method software, i.e., OpenSEES. The interaction phenomenon is assumed to
be affected by six different parameters. In the parametric study, these parameters are assumed to have various values in
accordance with the engineering practices. A total of 1620 possible combinations of the parameter values are addressed in this
study. 30 different numerical models are also generated as the ‘free-field cases’ to set a reference. The surface structure drift and
acceleration amplifications are used as a measure to evaluate the dynamic interactions. The response (i.e., drifts and
accelerations) amplifications are calculated as the ratio of the maximum surface structure response in any ‘case’ to the maximum
surface structure response in corresponding free-field case. Variation of the response amplifications with any of the investigated
parameters is addressed in this paper. The results obtained from the numerical analyses clearly reveal that the presence of a
buried structure in the vicinity of a surface structure can cause both amplification and de-amplification of the surface structure
responses, depending on the case parameters.
