摘要

This study consists of a numerical analysis of pile-soil structure interaction through the time history approach adopted in the ANSYS finite element software, where effect of Pile foundation along with interaction of soil and structure is considered. The study incorporates spectral values from four significant Indian earthquakes: Chamba, Chamoli, Bhuj, and Uttarkashi. The analysis considers three types of soil soft, medium and hard soil. The study proposes to assess dynamic response of pile foundation to different seismic conditions and type of soil. Notably, total deformation in soft soil was 45% higher than in hard soil under the Uttarkashi earthquake scenario whereas the maximum principal stress ranged from 10 MPa in medium soil to 5 MPa in hard soil under the Uttarkashi earthquake scenario. The research is useful for deciding on the specificities of seismic design for construction in areas with varying soil and seismicity parameters.
