Abstract
<p>Bulging is a coupled vibration between tank wall and content fluid. This phenomenon is induced by seismic ground motion. Generally, SUS panel tanks are divided into two parts by partition plates. There is a case of water leakage due to damage to partition plates caused by the earthquake. In this paper, we perform the eigenvalue analysis to calculate the natural frequency of the partition plate. Next, we perform a time history response analysis using this natural frequency to measure the von Mises stress and water pressure acting on the partition plate. The measured von Mises stress confirm the resonance with the partition plate section. Furthermore, water pressure becomes extremely greater when resonating, and we find that the current design guideline is improper.</p>
