Rammed earth (RE) is a soil-based construction material which attracts scientific researches because of its sustainable properties. This paper presents a numerical study to investigate the in-plane seismic behaviour of RE walls. First, an in-situ RE wall was modelled by the discrete element method (DEM). The robustness of the model was checked by comparing dynamic properties of the model with the experimental values. Then, an earthquake excitation was introduced to the model to assess the seismic behaviour of the RE wall studied. The signal was scaled at different amplitudes to assess the damages following different earthquake intensities. The drifts were recorded and the seismic behavior was discussed. � 2020, Springer Nature Singapore Pte Ltd.
