Abstract
LNG(Liquefied Natural Gas) has been considered as the green energy. Thus, the demand of natural gas is keep increasing around the world, and various studies are actively under progress about the LNG storage tank. To calculate the seismic forces of actual LNG storage tank, FEM model has to include inner tank, outer tank, pile and soil to implement the interaction between structure and ground. So, this paper is represent the study about inner tank model of three cases using Malhotra method in EN 1998-4(European Standard). The results of calculation were compared, and the most suitable to inner tank model was suggested.
