円筒タンク模型のスロッシング波高に関する一考察(都市基盤デザイン工学科)

Abstract

After the Tokachi-0ki earthquake, earthquake proofing of cylindrical tanks are demanded. In particular, the measure against a sloshing is demanded. However, there is not a method obtaining effective result in an actual tank. In this paper, we propose a wave height reduction method and explain about effects of it. This proposed method is used a support and a flat board as an instrument. At first, we performed an experiment of a shaking table using the cylindrical tank's model. We examined the wave height and the wave pressure of the sloshing. When we used the proposing method, we measured the wave height and the wave pressure too. Next, in numerical analysis, we calculated sloshing wave height in a condition same as an experiment and examined the propriety of numerical analysis.
