The Active Variable Stiffness (AVS) System is characteristic in its mechanical and logical control procedure to reduce building's response during earthquakes by establishing a non-resonant state with changing building's stiffness. In order to improve its accuracy in selecting appropriate building's stiffness during earthquakes, some new methods to detect building's resonance were proposed. The methods were originated with attention to the dominant period of the input motion, the dominant period of the response of each uncontrolled stiffness type, the difference in phase between the input motion and the uncontrolled responses, and the sign of the increment in the input energy. The effectiveness of the methods was verified with the results applied to an active base isolation system during 8 types of earthquakes.
