| Outline of Final Research Achievements |
After the 2011 Great East Japan Earthquake, the number of research activities about tsunami load and building performance against tsunami has been increasing. Although quantitative tsunami load evaluation has been proposed, quantitative safety evaluation against building collapse due to collision of tsunami-driven ships is still insufficient because of the limited number of studies. In this research, effects on building collapse due to collision of tsunami-driven ships is investigated, and the design procedure to avoid building collapse is proposed through collision tests of building column and frame specimens.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により，大規模津波が発生した際に生じうる，津波漂流船舶の建築物への衝突と，それによる建築物の崩壊に対する知見の蓄積が行われた。本研究で提案された，津波漂流船舶衝突に対する安全性検討手法は，柱の軸力保持能力評価にまだ課題を残すものの，将来の津波被害の低減を通して，安全な社会へ貢献するものと考えられる。
