CONTROL OF STRUCTURAL RESPONSE AGAINST EARTHQUAKES BY USING INFORMATION ON PREDICTED EXTERNAL FORCE

Abstract

This paper proposes an algorithm to control seismic response of structures by using information on predicted external force. The proposed control rule is composed of stationary feedback term and feedforward prediction terms. Numerical simulation in one degree of freedom system having one control system is used to clear the efficiency of this method. It shows that feedforward prediction terms act as bandstop filter of seismic wave and that the proposed method has more effective in control efficiency than stationary feedback control.
