ステンレス鋼製貯水槽の地震による側板破損原因の解明および地震対策案の検討

Abstract

The water storage tank damages by earthquakes have been reported. The damaged water tanks lost storage capacity. Therefore, it is impossible to supply satisfactorily water to evacuees. It is important to prevent such secondary disasters. Therefore, it is necessary to reduce damage to tanks due to earthquakes. In this study, seismic excitation experiments have performed to investigate the damage mechanism of the stainless steel panel tank. The purposes of this study is to clear the damages by focusing on the panel joints. And, clear the damage mechanism under the dynamic water pressure. From these results, seismic resistant method design will be suggested.
