Abstract
The oil piping was cracked by ground motions of the 2003 Tokachi-oki earthquake. A big fire occurred by the oil leakage from the crack on the tank yard. Investigation into the cause of the fire requires the understanding of the behavior of the piping during the earthquake. In this study, earthquake response analysis was conducted to obtain the displacement and the stress of the piping during the earthquake. This analysis used the actual earthquake waves which were observed on the tank yard. Also, the large deformation analysis was conducted in order to consider the depth of the defect in the piping.
