A review of the challenge to use dynamic FEM analysis in seismic design practice of quay walls after the Kobe earthquake disaster

抄録

Quay walls in Kobe Port are severely damaged in 1995 Kobe Earthquake Disaster. The fact that a very severe shaking was observed at the site revealed the difficulties and limitations of conventional seismic design process. Thus, the advanced dynamic FEM method has been implemented in the seismic design practice in Japan. However, in the process of implementation of dynamic FEM analysis in seismic design practice, various kind of effort have been made. In this paper, these efforts after Kobe earthquake are reviewed from the viewpoint of V&V (Verification and Validation) procedure. The achievement and remaining future tasks on the practical use of FEM after Kobe earthquake are summarized.
