Keywords:SUS panel tank, Bulging vibration, Attack angle

Various damages to SUS panel tanks have been reported due to the earthquake. These causes are due to the bulging vibration. In this paper, we carried out the time history response analysis of the fluid structure interaction with changing attack angles. This analysis clarifies the weak points of SUS panel tanks when the bulging vibration occurs. As a result, it was found to be maximum of the displacement at the attack angle 0°. As for the stress, corner members are the weak points regardless of the attack angles.
