| Research Abstract |
This study investigates the behavior of the second mode resonance in the liquid storage tanks with the single-deck type floating roof. The behavior of the floating roof is simulated by the numerical analysis method that we propose, and the deformation and stress in the pontoon are investigated in detail. The stress of the pontooncalculated by the design method notified by the Fire Defense Agency is compared with the numerical results. By these results, the validity and the applicability of the design method are discussed.
