FORWARD SPECTRAL FORECASTING OF GROUND MOTION WITH THE INFORMATION OF EARTHQUAKE EARLY WARNING SYSTEMS FOR STRUCTURAL CONTROL

Abstract

There has been steady progress in research and development of earthquake early warning systems and its application to structural control. In this paper our proposed methodology about forecasting frequency contents of strong motion is first introduced, then its application to feed forward structural control with the usage of semi active control devices is simulated, and lastly it is showed that non-resonance structural control can be achieved before the strong motion of an upcoming earthquake reaches to a building of interest.
