Abstract

The sloshing damping devices using floating net was developed for the damage measures of the oil storage tanks with floating roof by earthquake generated sloshing of liquid. In this paper, the shaking table tests with a scale-down model tank and the free vibration tests with a real model tank were executed and the effect of the floating net of sloshing wave height control was confirmed. Moreover, the presumption equation of the damping factor of the floating net was considered.
