The 2003 Tokachi-Oki earthquake caused severe damage of oil storage tanks due to long-period ground motions. After that, the technical standards of the Fire Service Act regarding the sloshing with floating roof tanks were revised. The influences of non-linearity of fluid behavior and 2nd mode sloshing were taken into consideration using FEA (Finite Element Analysis) code at this time. However, it is not enough that sufficient description about FEA model such as contact definition, time steps, number of element division, hourglass control and seal model. In this paper, the authors present the suitable model of sloshing simulation for floating roof in oil storage tanks using nonlinear FEA code.
