In the 2011 off the Pacific coast of Tohoku earthquake, tsunami caused movement damage such as drifting of oil storage tanks. It is reported that about 70% of the oil storage tanks damaged by the tsunami are small storage tanks of less than 500kL, and tsunami safety measures are extremely important to prevent and mitigate these tsunami damage. As tsunami countermeasures for small storage tanks, the authors have proposed two sliding/drifting countermeasures using CFRP, which are excellent in durability (corrosion resistance), workability, and strength. In this study, the full-scale steel tank was installed on the RC slab to conduct the large-scale tsunami hydraulic experiment to confirm the effectiveness of the two proposed countermeasures, and the CFD analysis was conducted for the experiment.
