| Abstract: |
Piles installed in seismically active regions are subjected to predominantly lateral loads due to earthquakes. Design of laterally loaded pile is mainly governed by its bending behaviour, which may be amplified under earthquake load compared to static loads. The influence of pile diameter on seismic response of single pile embedded in clay is investigated with a help of a three-dimensional finite element model. The model developed was validated through experimental/numerical results reported in literature. Subsequently a comprehensive parametric study was carried out by varying soil and pile parameters. The results of the numerical study are interpreted to estimate bending behaviour of piles under earthquake loads. It is found that the soil/pile characteristics, particularly, pile diameter have pronounced effect on seismic response of piles in clay. |
