Influence of Pile Diameter onEffective Pile Length under Earthquake Load

摘要

Piles installed in seismically active regions are predominantly subjected to lateral loads due to earthquakes. Design of laterally loaded pile is mainly governed by depth of fixity and/or effective pile length. Effective pile length under earthquake load may be amplified compared to static loads, and there are only few equations reported in the literature to determine the effective pile length under earthquake loads. These equations were developed based on parametric analysis, especially for a constant diameter and by varying pile length. However, influence of pile diameter on effective pile length has not been investigated so far and is accordingly carried out using 3-D finite element analysis, which is presented in this paper.
