Analysis Methods of Soil-pile-isolated Structure Nonlinear Dynamic Interaction

In recent years, the soil-pile-isolated structure nonlinear dynamic interaction (SPISI) has been one of the significant research issues in the field of structure seismic resistance. This paper reviewed the existing research on the SPISI field and sorted out the main analytical methods in the SPISI field, including theoretical analysis methods, time history analysis methods, model test methods and energy analysis methods, etc. On this basis, the current research results on the dynamic response of isolated structures considering soil-structure interaction were systematically summarized. Finally, the shortcomings of existing research and problems that need to be solved were analyzed and the relevant research recommendations for the imperfections of existing research were given. The research results can be used as a foundation for subsequent research in this field.
