Damage of Oil Storage Tanks Caused by Liquid Sloshing in the 2003 Tokachi Oki Earthquake and Revision of Design Spectra in the Long-Period Range

Abstract eng:
The 2003 Tokachi-oki earthquake (Mw=8.0) caused the severe damage to oil storage tanks such as fires and sinking of floating roofs by liquid sloshing excited by long-period strong ground motions. In order to prevent such severe damage due to future earthquakes, we predicted the velocity response spectra in the long-period range at more than 80 oil industrial complex districts in Japan, mainly based on the empirical method considering seismotectonic zoning. Based on both predicted spectra for earthquakes with maximum expected magnitude in each seismotectonic zone and damage pattern of oil storage tanks, we proposed design spectra with 210 cm/s in maximum as a function of period and district, which were adopted in the revised Japan Fire Service Law enforced on April 2005.
