As Japan is one of the most earthquake-prone countries in the world, various kinds of efforts regarding the issue have been carried out. In particular, seismic recordings have been conducted on existing dams in order to empirically compare the characteristics of earthquake input and dam response. In order to contribute to the further advancement of seismic safety evaluation and the design of dams, the Japan Commission on Large Dams released databases of earthquake recordings in 1978, in 2002 and updated it in 2014. The study will focus on records on two concrete dams: Tagokura gravity-dam and Kurobe arch-dam with recording devices located in the dam and also in the foundation. For each dam, a minimum set of 5 earthquake records from Magnitude 4 to almost 7 are chosen. The purpose of the present study is to get as much information as possible on the dam’s response by evaluating the first eigenfrequencies. Different methods of analysis (transfer function, frequency domain decomposition, cross-spectrum) will be considered and the variability of the results will be evaluated. The reproducibility of the results with different earthquake records will also be analyzed.
