Seismic Analysis Considering Soil-Structure Interaction

The case study on LNG storage tank, Inchon, Korea which is supported by pile foundation system is carried out using Abaqus. The dynamic analysis is carried out on a single pile of this storage tank varying the ground accelerations, as 0.08g, 0.18g, 0.28g and 0.38g and maintaining the duration constant as 25 s. The spectral acceleration at the different levels of the piles are used to obtain the transfer function which is the ratio of spectral acceleration of the pile to ground acceleration. This paper will present the seismic response of single pile subjected to an earthquake at its bottom.
