Soil-Structure Interaction (SSI) is an outstanding factor that influences the linear and nonlinear performance of any structure, and it can be taken into account as one of the most important and effective considerations on the seismic behavior of buildings. On the other hand, historic masonry buildings are specific and important structures, which are significantly affected by SSI. Preservation of these buildings is one of the main demands of every culture and every society; and evaluating the behavior of these buildings under natural events such as earthquake, considering aforementioned SSI phenomenon, is an essential step, in this regard. In this paper, the impact of SSI on the out-of-plane behavior of an ancient building in Iran, named Arge-Tabriz, has been investigated utilizing Finite Element Method (FEM). Modal and nonlinear Time-History (TH) analyses results revealed that SSI has a significant decreasing effect on the acceleration response due to removing the effective mode vectors from the resonance area of the acceleration response spectra. On the contrary, SSI has a remarkable increasing impact on the displacement response of Arg’s walls according to the displacement response spectra.

土壤-结构相互作用（SSI）是影响任何结构的线性和非线性性能的重要因素，可以将其视为建筑物抗震性能的最重要和有效的考虑因素之一。另一方面，历史悠久的砖石建筑是特殊而重要的结构，受SSI的影响很大。保存这些建筑物是每种文化和每个社会的主要要求之一；在这方面，考虑到上述SSI现象，评估这些建筑物在地震等自然事件下的行为是必不可少的步骤。在本文中，已使用有限元方法（FEM）研究了SSI对伊朗古建筑Arge-Tabriz的面外行为的影响。模态和非线性时间历史（TH）分析结果表明，由于从加速度响应谱的共振区域中删除了有效模式矢量，SSI对加速度响应的影响明显减小。相反，根据位移响应谱，SSI对Arg壁的位移响应的影响显着增加。
