Abstract

<p>Tsunami-driven ships can cause a critical damage to buildings when colliding with their columns. In this paper, the authors report a collision test using reinforced concrete frame specimens and steel bars as colliding ships, and propose quantitative evaluation procedures of the maximum response displacement of the columns. The maximum column displacement is estimated using balance of the energy dissipation capacity of column specimens (calculated using estimated backbone curve) and the energy transferred from the steel bars (calculated using kinetic energy and coefficient of restitution). The proposed procedures could accurately estimate the maximum response deformation of the columns.</p>
