Summary Structure‐soil‐structure interaction (SSSI) phenomena under earthquake excitations are investigated in this paper. Based on the results of the shaking table test, this work presents a 3‐dimensional finite element numerical simulation method using ANSYS software. In the simulation, an equivalent linear model is assumed for soil behavior, and contact elements are adopted to consider the nonlinearity state of the interface between foundation and surrounding soil. In addition, constrained equations are added to manage the uncoordinated degrees of freedom. By comparing the results of the finite element analysis with data obtained from the shaking table test, the dynamic response of the shaking table test can be simulated properly. Finally, the dynamic response of adjacent structures considering the SSSI effect is analyzed. The results show that with increased excitation, contact pressure, strain amplitude, and pile slip increase, whereas the peak acceleration magnification coefficient decreases. These results are significant for studying the effect of SSSI on seismic responses of structures.

“…The first known study was performed by Warburton et al [8][9][10] , and the following 1970s was the initial phase of the SSSI study [3][4][5][6][7] . The rapid progress of SSSI studies in subsequent decades has been stimulated by the needs of nuclear power plants (NPPs), which always consist of a reactor building adjacent to a turbine building and control building [21][22][23] . In recent years, apart from its continuation in NPPs [24][25][26][27] , studies related to the SSSI have focused more on structure clusters in urban areas.…”

“…They have observed some detrimental effects on structure response during an earthquake when a target wall is located adjacent to a larger and heavier one. More recently, Nakagawa et al [26] and Kitada et al [27] performed a large-scale force vibration test for a cluster of NPP and found that the appearance of Control Building can result in a decrease in Reactor Building response in the vicinity of the structures' resonant frequency. Xu et al [28] and Broc [29] have conducted back-analysis for the above large-scale force vibration tests, using SASSI program and couple boundary element method and finite element method.…”

: In a megacity, structure response during an earthquake could be increased or decreased due to effects from neighboring structures, through structure-soil-structure interaction (SSSI). In the present study, a series of dynamic geotechnical centrifuge tests are carried out to investigate SSSI effects on responses of structure with various characteristics of mass, height, and natural frequency. Experimental observations are focused on the effects of the distance between two structures, type, and peak acceleration of input excitation. A period lengthening is observed in the soil-foundation-structure interaction (SFSI) effects of all structures. It is monitored that an increment in response of smaller structure and a decrement in response of larger structure, compared to isolated structure, due to SSSI effects. Unfavorable distance reveals that the most significant increment in response of S2 structure occurred at approximately one-fourth of wavelength transmitted from the vibrating adjacent structure. More severe SSSI effects are found under a lower input earthquake acceleration. It is found that both height and mass ratios, between two adjacent structures, are particular parameters on SSSI, resulting in increment or reduction of structure response.
