Abstract |
In the case of fluid storage structure, hydrostatic pressure acts on the structure due to fluid surge during an earthquake. At this time, hydrodynamic pressure of the fluid charge not only by the strength of the earthquake but also by the sloshing height of the fluid. Factors affecting the change of load include the size, width and height of the fluid storage structure and height of fluid, time-history shape, etc. This paper wanted to identify the relationship between the earthquake shape and fluid free surface shape. The sloshing height measured the height of the fluid by applying earthquake to a tank whose width 500mm and comparison of the experiment and analysis. In addition, the shape of the fluid free surface was measured while varying the shape of earthquake and effective of the shape of earthquake of the fluid was analyzed.
