STUDY ON TSUNAMI DRIFTING COUNTERMEASURE OF OIL STORAGE TANK WITH BASE FIXED USING CFRP

Abstract

 In 2011 Tohoku Pacific Ocean Earthquake, many oil storage tanks located in the coastal area drifted, and fire caused by spilled oil is a problem. Many of the oil storage tanks damaged by the tsunami are small-scale tanks that are less than 1,000kl, and these countermeasures for tsunami drifting are urgent. Therefore, the authors suggest fixed between the tank base and the RC slab using CFRP sheet that is excellent in durability, workability and tensile strength. In this paper, to confirm the influence on this measure at earthquake, shaking table test using 20kl tank was carried out. In addition, the effect of countermeasures against drifting during tsunami wave action was examined by nonlinear finite element analysis.
