Abstract. The objective of this study is to present a new macroelement modeling, based on the principles of the hypoplasticity theory, and aimed at better representing the soil-structure interaction (SSI) during seismic events. Its target is to overcome the limitations of the three-dimensional model by Grange (2008), particularly when it comes to significant instabilities or material fatigue the structure reaches during cyclic loading, which leads to a larger gap between reality and the model. A physico-mathematical analysis of the soil-structure interaction is therefore proposed, and the model is numerically integrated into a computation code to verify its performance against the experimental results. This approach could contribute to improving seismic standards in terms of performance-based design.
