Different methods such as limit equilibrium and pseudo-static have been widely used for seismic analyses. These methods cannot completely simulate the behavior of site and continuous changes of the acceleration and velocities with time during earthquakes. Therefore, they do not represent the real model. In this study, a seismic analysis of an anchored-wall was performed by applying acceleration history. The behavior of the anchored-wall is simulated during earthquake by records of earthquake obtained by seismic studies on the project sites. The acceleration records were filtered and corrected before applying to the model by using seismosignal software. The main goal was to determine the displacement at different points of the anchored-wall and forces in anchors. For the analyses, finite difference method was employed considering an elastic-plastic formulation in continuum mechanics. The three-dimensional analysis was implemented using FLAC3D. The three-dimensional simulations found to be more reasonable in comparison with the results provided by the two-dimensional analysis. Despite increases in the displacements and forces, the complete collapse did not occur.
