A REPORT ABOUT DYNAMIC FLUID PRESSURE BY SLOSHING ON THE WALL OF A REAL WATER TANK

Abstract

 It has been reported that there were many cases of damages at rectangular water tanks in water supply facilities, under Tohoku earthquake. These many cases, wall panels are destroyed. This kind of dameages is thought to be caused by sloshing which is risen by long term earthquake. In this paper, the authors measured water presser by sensors at surface of the wall through experiment with real scale water tank on large shaking table. The purpose is examining an effect on wall by variety of shake direction angle, shake time and shake amplitude and understanding the differences. In the end, we found out some possibility of that the part near corner and roof of tank being structural week point.
