Abstract
In 1995 Hyogo-ken Nanbu Earthquake, many rectangular water tanks were damaged. Rectangular water tanks are mainly produced by fiber reinforced plastic (FRP) panels or stainless steel panels in Japan. Though there have been conducted many seismic tests on FRP panel tank, few tests on stainless steel panel tanks. In conjunction with this, the shaking table tests of two different types of stainless steel panel tanks were conducted. One was the column reinforced tank. The other was the tie beam reinforced tank. From the shaking table test results, the column reinforced type tank was found to be superior in the characteristic of self standing than the tie beam type tank, thus the superiority of seismic performance of the column type was shown. The measured water pressure data were compared and discussed with the existing design formula and the potential theory calculation.
