The earthquake occurred in the northern part of Osaka Prefecture around 7:58 on June 18, 2018. On the Hanshin Expressway, the permanent seismic observation was performed using measuring instruments installed in the structure, and many earthquakes were also observed in the earthquake. In this study, we investigated the response reproducibility by the dynamic analysis model used for the design, using the measured seismic waves.
In the seismic response analysis in which the acceleration measured on the foundation is directly input to the lower end of the dynamic analysis model, the displacement of the other observation point can be approximated, and the validity of the analysis method was confirmed.
