Abstract
The National Research Institute for Earth Science and Disaster Prevention (NIED) is now conducting for constructing a three-dimensional full-scale earthquake testing facility (E-Defense). This facility has 24 actuators to supply enough power to the shaking table, and will be equipped basic controller that is designed by Three Variable Control (TVC) technique. However the table was designed lighter than the capacity of maximum weight of test structure, it is supposed to have interaction between the test structure and the shaking table. Therefore, to equip a more highly developed controller, we should understand the property of table-structure coupled system with this basic controller. This study shows a simulation result of the structure-table coupled system with TVC.
