Fundamentally, the stability of masonry structures is dependent on the soil-basement wall interaction. Due to the ease of calculation and design of retaining walls by the quasi-static method of Mononobe-Okabe (M-O), this method has been widely used. However, the results of numerical models and experimental data have shown that this method is not very accurate, and the design is either very conservative or is unsafe. Since, in Iran, the use of masonry structures without reinforcement is predominant, in this study, the dynamic interaction between soil and masonry walls has been evaluated. This study has been conducted utilizing a 2D Plane Strain Finite Element Model. The behavior of the wall before cracking is idealized as elastic plate. After cracking, the strength of the wall drops very quickly, and, in this case, the remaining strength can be ignored, which can be assumed as having collapsed. Considering the geotechnical aspects that normally occur in practice, they have been simulated to produce the state of rest (
