Transcripción del abstract original del autor: In this study, preliminary earthquake response analysis of 200,000kl large capacity aboveground LNG storage tank for the basic design section under development by DAEWOO E&C Co. LTD has been performed. In this study, more accurate seismic response analysis considering fluid-structure interaction by using a general-purpose finite element analysis program ANSYS has been performed. From the results, which comparable to the theoretical solutions, of modal analysis on inner liquid, it has been validated the modeling of LNG liquid by finite element. Base on these results, the modal analysis on fluid-structure interaction system of LNG storage tank also has been conducted. Finally the seismic analysis of 200,000kl large capacity LNG storage tank has been carried out in time domain.
