Seismic Analysis of Steel Pile Type Pier Considering Effective Stress

In this study, seismic analysis of steel pile type pier was done by applying the pore water pressure in accordance with the water depth. In order to analyze the behavior of earthquake quay structure due to pore water pressure, the finite difference analysis program FLAC 3D was used. the seismic analysis compares the horizontal displacement of the quay top based on the total stress and the effective. From numerical analysis, it was concluded that seismic response of pier increases if effective stress of ground soil is taken into account.
