Abstract

This paper proposed the establishing procedure and introduced an OpenSessPL for investigating dynamic p-y curves in liquefying ground based on the simulated shaking table tests for pile-soil-bridge structure were conducted successfully corresponding to liquefying ground covered with clay layer simulated as a middle circumference of three layers adopting reinforced concrete single pile-pier exposed by a series of sinusoidal and EI centro earthquake events wave of different amplitudes and frequencies. A series of numerical simulations based on the established 3D finite element analysis method was carried out by including earthquake events to investigate the deveplod of p-y curves due to the effect of design parameters such as; pile stiffness, the internal angle of sand and the depth of pile insertion. The mentioned parameters beside seismic motion shape, peak acceleration (g) and degree of ground inclination have a certain theoretical and practical significance for seismic design related to lateral resistance and pile displacement.
