Large earthquakes occurring worldwide regularly renew the interest in the analysis of the post-seismic serviceability of Geosynthetic Reinforced Soil Walls (GRSWs). Several post-earthquake reports show that, differently from other types of retaining walls, GRSWs have generally exhibited a satisfactory performance characterized by a ductile behavior against seismic-induced deformations. Similarly, experimental data concerning shaking table and centrifuge tests emphasize the satisfactory seismic performance of GRSWs. In this vein, a simplified displacement-based predictive model, aimed to the evaluation of the seismic performance of GRSWs in terms of magnitude of seismic-induced permanent displacements, was proposed and, using the results of a parametric analyses, the main peculiarities of the seismic performance of GRSWs are discussed in the paper focusing on the possible coupling between the frequency content of the input motion and the vibration frequencies of GRSWs and on the influence of the mechanical properties of reinforcements
