Development of a High Accuracy Numerical Model for Predicting Motion of A Floating-Type Evacuation shelter from Tsunami with Eccentricity

Abstract

A floating-type evacuation shelter from tsunami is the facility which is swepted in tsunami. Therefore, for establishment of the shelter on site, it is an important task to predict motion of the shelter with accuracy in terms of strength for tsunami fluid force and safety of evacuees. In this study, a numerical model for prediction of translational and rotational motion of the shelter is presented. According to comparison with laboratory experimental results, calculated results on translational and rotational motion reasonably agree with experimental ones with accuracy.
