High Seismic safety reliability is required for nuclear power plant. Usually equipment and piping installed in nuclear power plant are assumed to be rigid, and are designed by using static seismic load. However seismic load is cyclic load, thus it is very important to grasp dynamic vibration characteristics. In this paper, forced vibration experiment by artificial earthquake wave is carried out then experimental results are evaluated from the viewpoint of the Energy Balance that is varied method for dynamic evaluation.
