A series of hydraulic model experiments were carried out to investigate tsunami wave load acting on a tsunami evacuation building with openings. We have found that 1) wave impact force can be dominant only under restricted conditions, 2) existing design formula predicts tsunami wave pressure values on the safe side, and 3) due to the openings, tsunami wave force acting on the building decreases by a factor of (1-aperture ratio) or smaller. We also carried out a numerical experiment, succeeding to reproduce the results of physical experiments.
