Introduction The pile enhances seismic stability of the infrastructure and the small building through the transferring and distributing applied seismic loading and all the other applied load to the infrastructure in a suitable subsoil location. A pile with a suitable prediction of working mechanism, settlement type, and failure pattern are require for minimizing construction costs.

The prediction technique has been applied for damage evolution, fracture in the mixed-mode, and fatigue strength (Albinmousa et al., 2020; Marsavina et al., 2017a; Marsavina et al., 2019; Song et al., 2018). The prediction method supports future events for engineering judgment through select sampling from the group of the data are available in most phenomena including engineering science. The predict future event has a significant influence on safety and economic engineering products. On the other hand, the prediction helps to minimize engineering analytical processes and time consumption in product design. The statistical method was employed to identify the strength of the material and failure possibility based on the fracture strength of irregularly-shaped particles by Qian et al. (2019), and also the statistical method was used to evaluate the resultant stress applied on rock and cohesive soils when the specimen was diagonal cross-section, and the loading interaction was assessed by Lei et al. (2019), however the statistical method applicable in the several engineering problems either linear or nonlinear loading are applied to the model. The statistical analysis is a promising method and can make comparative analysis for the new suggested method. The pile group with considering working mechanism, multilayered soil-structure nonlinear interaction due to seismic loading, the differential settlement of concrete footing because of concrete footing shape design, timber structural element seismic design, tsunami modeling, embankment-subsoil subjected to the nonlinear loading using shaking table test and assessment of soil bearing capacity by considering mechanical properties of the soil are reported in the literature (Chen et al., 2019; Namdar, 2020; Namdar et al., 2019a; Namdar et al., 2019b; Namdar and Nusrath, 2010; Namdar and Pelkoo, 2011; Namdar and Pelkoo, 2009), they can be more in deep investigate and predict with using statistical models. The pile exhibit with different settlement mechanism based on the pile geometry, type of construction materials for build a pile, nature of the applied load, and the soil type. Considering these factors will not support exact the pile seismic response prediction and the application of seismic load in the analytical process require time to complete an analytical process. The statistical model is applicable in seismic analysis of the pile settlement. In this study, to predict settlement of the pile, in two major lateral directions independently, the important peaks of the seismic loadings and whole recorded seismic loading were applied on the pile and to predict the accuracy of the pile settlement the statistical model was applied, to verify results of the analytical results, statistical models have applied to the settlement range and density trough the distribution probability of settlement. 2. Modeling and analytical process Figure 1 displays the geometry of the pile model was simulated and subjected to the near-fault ground motion. The square concrete pile of 0.3 (m) x 0.3 (m) cross-section dimensions and with 18 (m) length was simulated. The pile is modeled with an equal thickness along with the height of 18 (m).
