The purpose of the present study is to analyze the response of Gas Utility subjected to Earthquake and to discuss the failure prediction of Kogas Storage Tank. Initially here, characteristics of Earthquake are reviewed and then earthquake-resistance Design is investigated based on previous earthquake hazard cases. Next, considering the distribution of the transverse permanent ground displacement and equivalent spring constant effect, formulae obtained by a beam theory are established to analyze PeungTak Center Control Room. This analysis was performed without consideration of axial effects. So the finite element analysis was used in order to consider the axial stiffness of Structure.
