Abstract
The Hanshin-Awaji earthquake disaster occurred in Kobe area of Japan in 1995. Japanese government has decided to construct a three-dimensional Full Scale Earthquake Testing Facility from the lessons of this earthquake disaster. The facility is under construction of the supervision of the National Research Institute for Earth Science and Disaster Prevention (NIED). The purpose of constructing this shaking table is to conduct fracturing and collapsing tests of full scale structures. In the tests, the traditional operation and control procedure such as the trial excitation method for the shaking table cannot be effective, because dynamic property of the test structures varies with the progress of fracturing and collapsing. The need for developing new operation and control methods for the shaking table is high and urgent. In this paper, dynamic interaction behaviors of the shaking table with a bi-linear test model is firstly studied and reducing the interaction effect from the motion of the shaking table by employing the Minimal Control Synthesis (MCS) algorithm is tried, and the efficacy of the MCS algorithm through the simulations and experiments by using the two dimensional small scale shaking table with a bi-linear test model structure is shown.
