| Outline of Final Research Achievements |
The Great East Japan Earthquake caused damage of water tank. Against the impending earthquake disasters such as the giant earthquake, we understand the dynamic behavior of the water tank and also control the sloshing phenomenon. In previous studies of the authors, it has been proven that there is a decrease effect of damping panels device against water tank. However, construction of the dampers is poor, spent a lot of time for construction. So, we devise a method that is possible to improve the workability due to assemble the damping device in the 8 shape. We carry out vibration experiment with the actual water tank, and investigate the decrease effect against the sloshing phenomenon and the workability of this damping device. As a result, workability of damping device is much better than conventional damping device, we found that this damping device is also possible to exert the same decrease effect as conventional damping device about the wave height level and reduction rate.
