Tsunami Response Analysis of Pile-Supported RC Buildings in Onagawa Town Due to the 2011 Great East Japan Earthquake and Tsunami
Pile-supported reinforced concrete buildings were uplifted and overturned due to the 2011 Great East Japan Earthquake and Tsunami. It is important to understand the mechanism that caused such damage to enable us to build resilient coastal communities against mega tsunami. In the present paper, we study numerically the difference in tsunami response among overturned buildings and surviving buildings in Onagawa town. The following conclusions have been obtained. (1) We cannot explain from the view point of only the hydrodynamic force whether these buildings overturned or not. (2) The pile resisting moment makes a significant contribution to overturning resistance for most of overturned buildings, but not for the surviving buildings. (3) The failure of the piles of overturned buildings could be caused by only the tsunami hydrodynamic force.
