Seismic response analysis for an arch dam considering displacement and vibration properties based on measuring data

Abstract

In order to evaluate the seismic performance of an arch dam, we have developed a three dimensional finite element model by which static behavior and dynamic properties of the arch dam can be reproduced. The seismic performance of Hitotsuse arch dam was evaluated by using this model. These results were compared with measuring data such as displacement and ambient vibration, and it was confirmed that these results reproduced the characteristic of a real dam, and then, the seismic performance of Hitotsuse arch dam was confirmed.
