Abstract
A float-type evacuation shelter has ever been proposed as one of urgent evacuation facilities by one of the authors. In this study, a new shelter covered by a sphere shell was proposed in order to control rotation of evacuation space for refugee. A series of hydraulic experiment was carried out to understand motion of the outer spherical shell and inner shelter. The outer shell had been kept rotating immediately after tsunami attack. In contrast, the inner shelter rotated once, but reverted back to the initial condition. The possibility of control of rotation velocity of the inner shelter by the weight was implied.
