Abstract

In the present study, pseudo-static approach has been used to assess the behaviour of a single pile subjected to seismic loading by FDM. Imperial Valley earthquake accelerogram has been scaled to 0.10 g, 0.13 g and 0.16 g peak bed rock acceleration (PBRA). These motions have been used to carry out equivalent linear method of ground response analysis (GRA) to get the peak ground acceleration (PGA) and deformation profile of soil column. The effect of shear wave velocity of soil mass, pile diameter, input motion, vertical load at pile head on behaviour of both free head and fixed head piles has been studied using pseudo-static approach. The study shows that the increase in PBRA and vertical load will increase the pile deflection and bending moment, whereas the increase in shear wave velocity of soil mass will cause reduction in pile deformation but an increase in bending moment.
