シングルデッキ型浮屋根貯槽模型の地震時スロッシング実験 Model tests on sloshing in a cylindrical oil storage tank with a single-deck type floating roof under seismic excitation
Shaking table tests are carried out to investigate the sloshing in a cylindrical oil storage tank with a single-deck type floating roof. The experimental tank is a stainless-steel cylinder of 1, 600mm in diameter with a floating roof composed of an inner deck made of polyvinyl chloride sheet and an outer pontoon made of acrylic plate. The optical motion capture system is employed to measure the roof displacement over the whole roof surface. Free oscillation tests as well as seismic oscillation tests are performed using the 2003 Tokachioki earthquake recorded at Tomakomai K-Net station. It is observed that the nonlinear oscillation modes with the number of circumferential waves 0, 2 and 3 may occur, which cannot be predicted by the linear theory.
