Abstract
The 3-D Full-Scale Earthquake Testing Facility (E-Defence) is now under construction in Mild City in Hyogo.The Test model considered for this facility has a mass of 1200 tons compared to 1he shaking table mass of 750 tons, i.e.,1.6 times as heavy as the shaking table. For this reason, it is considered that the reaction force from the test model to the shaking table is considerably large, and this degrades vibration re-create performance of E-Defence. Li this study, the controller is designed by using Reaction Force FeedbackThe effectiveness of the control technique is verified through simulation and experiment
