Abstract
In order to experimentally confirm the dynamic characteristics of embedded reactor building, shaking table tests and hammering tests were carried out, utilizing hard ground model made of hard silicone rubber and structural model made of aluminum which is embedded by soft silicone rubber. From the test results, it was confirmed that embedment increases system frequency of soil- structure interaction system, the ratio of elastic deformation of structure and radiation damping. Using the transient data of impulse responses, impedance function and foundation input motion could be identified in a smooth shape. Simulated results for non-embedded case by wave propagation theory and axi-symmetric FEM showed fairly good agreement with test results.
