Dynamic analysis of lateral pile under seismic loading is performed in this thesis. As an analytical model, the Beam-on-Winkler Foundation Model is used for this study because of its simplicity and acceptible accuracy. The method suggested by Kagawa and Kraft, which can account for non-linear effects, is used for the dynamic p-y relationship. This relationship is found to be the most important factor in analysis. Group pile effects are also considered approximately.
The results of dynamic analysis show that a pile without supporting mass follows the soil movement; in the case of a pile with supporting mass, the relative displacement between the soil and the pile occurs. When designing piles, it must be considered that piles have to resist the curvatures originated by the soil movement.
