Abstract

Super structure and pile foundation of Konan junior high school were severely damaged by the Tokachi-oki Earthquake, September 26, in 2003. The objective of this study is to investigate the damage by earthquake response analyses. The analyses of the structure on pile foundation are conducted using a numerical model taking into account an effect of soil nonlinearity. The observed strong motions in the borehole array at Atsuma Site by KiK-net are employed as an input motion to the soil-pile foundation-structure system. It is found that the super-structure had a lot of shear cracks by differential settlements induced by the compression failure at the pile head, and that the pile foundation damage at the pile head was caused not only by inertial forces of the super-structure but also by large soil displacements in very soft silt layer.
