| چکیده | ||
| This study, investigates the factors impacting on sloshing phenomenon of the tank structures including geometry, burial rate, and installation of T-shaped baffles under two different earthquake records. The results indicate that the tanks with larger dimensions will experience less sloshing height. Moreover, length, height, and the freeboard, respectively, are effective in lowering the roof force. However, freeboard plays a more important role comparing with the burial rate of the tank in reducing the roof force. Note that as the freeboard and burial rate increase, the roof force decreases. The results represent that decreasing the height to length ratio of the tank reduces the maximum sloshing height. Finally, using the energy dissipation ratio concept, it is observed that the tank with baffles shows much better performance with the energy dissipation ratio of about 96%, comparing with the burial approach in which even the tank under 100% burial rate just dissipates less than 50% the energy induced by the sloshing waves. | ||
