| Outline of Final Research Achievements |
Since the 2011 Great East Japan Earthquake, the need for tsunami refuge buildings which contribute to protect human lives during tsunami disasters has been increased. In this proposed subject, safety evaluation of a tsunami refuge building by dynamic analysis using the Adaptively Shifted Integration (ASI)-Gauss code was carried out. The following three load conditions were considered; seismic excitation, fluid force which contains buoyant force and tsunami force, and impact force by tsunami debris. By performing the analysis with the loads consecutively applied to the tsunami refuge building, it was confirmed that a tsunami load had a great effect, and the impact force of debris even higher effect, on the damage of the building. In addition, tsunami fluid force acting on a structure was evaluated by performing a hydraulic experiment. Also, some useful information such as scope of application of estimated wave force were obtained by applying the stabilized finite element method.
