A Study on the sloshing behavior and its suppression method for the rectangular tank

Abstract

The damages of water tank, which gives rise to sloshing motions during an earthquake with long-period, have been reported in the present study. Herein, experimental studies have been performed to investigate the sloshing behavior of rectangular tank with the different dimensional aspect ratios, under the different excitation angles. In addition, the behavior of tank with a special aspect ratio (i.e., near to 1) has been examined in detail. Also, the sloshing suppression methods using plastic filters have been developed based on the present experimental results. Finally, the effective variables, such as position of filter installation, depth, length and area for the wall of tank, have been proposed.
