Abstract The seismic behavior of reinforced soil retaining walls with polymeric strips is examined. A series of 1-g shaking table tests were employed on 80 cm high reinforced-soil wall models. Also, some uniaxial tensile and pullout tests were performed in reduced-scale models to determine the best material to be used instead of polymeric strips in models
