Some sloshing response analyses of floating roofs using commercial code LS-DYNA have been reported thus far, but there are unknown factors like the damping ratio in the analyses. In this paper, the effects of several parameters which are considered to have influence on damping in the analyses are investigated. On that basis, several earthquake response analyses were performed and the results were compared with the ones which have been already reported. Because the results of LS-DYNA give smaller response, some precautions when applying LS-DYNA to sloshing analyses are shown.
