Settlement magnitude in Y - direction

Fig. 6. The frequency of settlement magnitude in X and Y directions.

The mode range of the pile settlement is modeled in figure 7, it defines concerning the extracted peak seismic loading in both X and Y directions, figure 7 was demonstrated the distribution density of the settlement associated with the applied seismic loading in the X and Y directions. In the applied seismic loading at the X direction, the displacement of the pile is not like the Y direction, the frequency of the nonlinear settlement of the pile at Y direction is higher. Due to the extracted high acceleration peaks of the seismic loading with different characteristics the soil pile interaction and the settlement density behave in two mechanisms which are modeled in figure 7. The settlement frequently occurrence following two different patterns in X and Y directions. The range of the settlement density is the different between the X direction with Y direction in a soil-pile interaction.
