    Computational Modelling of Soil-Structure Interaction for Piles in Soil Undergoing Liquefaction

    Earthquake induced liquefaction increases pore water pressure reducing the soil stiffness as well as soil shear strength. Due to this, considerable buckling is generated in the pile resulting excessive bending moment damaging the piles. In this paper an attempt is made to investigate the response of pile under liquefied soil using spectrum compatible accelerogram corresponding to the maximum credible earthquake for the most sever seismic zone of Indian standard. The pile-soil interaction is simulated considering pore water pressure with finite element model (FEM) in OpenSees platform. Finally, a comparative study is carried to show the effect of liquefaction on pile response.
