15WCEE | Evaluation of Lateral and Buoyant Forces on Reinforced Concrete Buildings by the Tsunami of the 2011 East Japan Earthquake [pdf]

Tsunami waves associated with The Great East Japan Earthquake on March 11, 2011, caused serious structural damages to reinforced concrete building structures, such as story collapse and base overturning. In this paper, the equivalent loads on the building structures were estimated from the damages in relation with the velocity and buoyancy of the tsunami. The drag force on building structures can be given by a function of the tsunami velocity, which was correlated with a distinction between inun
