Japan is an earthquake prone country among the world. Especially, the Southern Hyogo prefecture earthquake occurred in 1995 hit by enormous damage. Thus, structures in Japan are desired high safety. Against such a background, seismic technologies have been actively studied and developed. Seismic isolation system is one of the seismic technologies. Seismic isolation system isolates the structure from the ground. Thereby, acceleration input to structure can be reduced. However, seismic isolation structures are few compared to the total number of structures. Consequently, seismic observation records of seismic isolation structures are few in number. In order to improve seismic safety, seismic observation record of the structures obtains to important in earthquake. In this study, we deal with a seismic isolation structure of Tokyo Denki University, we conducts seismic observation since December 2011. In this paper, we investigate relationship between the intensity of the earthquake in construction site and the natural frequency of the target structure by using seismic observation record of the target structure. And, analytical model in constructed by using the above relationship. After that, analysis result by the analytical model and seismic observation records are compared. Thereby, the reproducibility of the analytical model is evaluate.
