Outline of Final Research Achievements

The load effects on buildings of innundation flow caused by uncontrollable events such as tsunami, flood, and storm surge were investigated in this study by means of hydraulic experiment. Among various load effects, drag force and uplift force were forcused, because these two are the most serious factors for the safety of hydro-resistant buildings. The methods of calculating the drag and uplift forces were proposed for buidings of cuboid and cylindrical shapes, which will be substantially useful for the design of flood refuge buildings and eventually for hydro disaster mitigation.
