A STUDY ON PREDICTION FOR INCIPIENT MOTION OF A FLOATING-TYPE EVACUATION SHELTER FROM TSUNAMI

Abstract

 As an urgent and temporal evacuation facility from tsunami, a floating-type evacuation shelter has been proposed. In order to understand translational and rotational motion of the shelter after tsunami attacks, hydraulic experiment was carried out. On the basis of experimental results, the relationship of translational and rotational motion of a shelter and wave property is presented. A numerical model for prediction of motion of a shelter is presented. According to comparison with experimental results, calculated results on translational and rotational motion agree with the order on experimental ones. It is found that improvement of the presented model is acquired for more accurate prediction of motion of a shelter.
