Model test on interaction of reactor building and soil-Part 2

Theoretical studies of soil-structure interaction have progressed in recent years. At the same time, experimental studies to verify the theoretical results have been carried out energetically. These experimental studies, however, have been mostly conducted by means of vibration tests or earthquake observations individually. In order to investigate experimentally the effects of soil-structure interaction, it is desirable to carry both the forced vibration tests and the earthquake observations of the same models. To this end, the earthquake observations were conducted to obtain the dynamic behaviors of soil-reactor building system during earthquakes and to compare them with the results of the forced vibration tests. The results are described in this paper
