چکیده: Abstract: Abstract Although the dynamic analysis of structures has been of interest to researchers since the beginning of the 20th century, the consideration of soil effects in these analyzes is not very old. In recent years, the issue of considering the effect of soil in seismic analysis has increasingly attracted the attention of designers. This issue has been given special attention by international regulations in the last ten years. Based on this, it is predicted that in the coming years, the designers of large and medium engineering structures will need the knowledge of soil and structure interaction. In this research, the structure is modeled using SAP software. Then, assuming a rigid foundation, the structure is modeled in ABAQUS software. Also, to avoid the complexity of the problem, the structure is modeled using beam elements. In the following, soilfoundation-candles are modeled in a single set. Earthquake is applied to bedrock as acceleration. In this research, the effect of the type of connection between the foundation and the pile on the soil-structure-pile interaction has been investigated, and finally, the results of the analysis and investigations show that the displacement, anchorage, and foundation shear created in the structure, when The soil of the construction site has been improved by reinforced pile. The connected pile has a better performance on the structure than the Un-connected pile.By increasing the thickness of the mattress layer, the amount of displacement, anchoring and cutting of the base of the structure has increased.
