DEVELOPMENT OF TSUNAMI DRIFTS DAMAGE-FORECASTING METHOD CONSIDERING INDETERMINACY AND BUILDING EFFECTS

Abstract

 In this research, a damage forecasting method which considered indeterminacy of each tsunami drift and effects of buildings was developed. As typical indeterminacy of tsunami drifts, the drift starting depth, the drag coefficient and the added mass coefficient were considered, respectively and allocated buildings were considered. Some numerical model tests were carried out. The results could show the significance of drifts characteristic indeterminacy and effects of building cllapsed by the tsunami.
