Further implications of this research extend to seismic design considerations, emphasizing the importance of restricting maximum pile moments and the subsequent determination of values for optimal foundation performance. The presented formulas and designations conform to established building codes, adding credibility to the study's findings. As future research avenues, exploring the dynamic behavior of pile foundations under varying soil conditions and incorporating advancements in material science could enhance the robustness of foundation design methodologies. In conclusion, this study contributes valuable insights to the nuanced understanding of pile foundation behavior under diverse forces, offering a foundation for further advancements in geotechnical engineering and structural design.
