A 3-D Full Scale Earthquake Testing Facility (E-Defense) was built in Miki Hyogo in January 2005 by NIED. The E-Defense makes it possible to do 6 DOF shaking tests. The E-Defense reproduces the earthquake wave which was actually observed. The testing model for the E-Defense is assumed about 1200 tons while the shaking table mass is about 750 tons. The mass ratio becomes substantially large, and greatly influences shaking performance. Since destruction experiment is irreversible, it must be assured that the experiment will not fail. Therefore simulation tools are needed which allow us to understand shaking performance in advance. In this research, a dynamical model of table system which includes the control system of E-Defense and the test body is made. And it aims at the development of simulation tools that can verify the performance.
