has a higher frequency in the vibration compared to model 1. Additionally, a higher magnitude is observed in model 2, but it is not in the final stage of the numerical simulation.

Fig. 6. The statistical model for nonlinear displacement from the simulation at all stages of the simulation. In literature was indicated that the higher fit in R 2 in the statistical modeling for geotechnical engineering is evidence for the reduction of differential displacement of multilayered soils when the model is subjected to seismic excitation in the horizontal direction (Namdar and Satyam, 2021). According to the statistical model of the present
