The Active Variable Stiffness System with the autonomous adaptive control makes the structure the time-variant system. As the dynamic response process of this system is described as the linkage of dual linear systems, the response property is theoretically derived from the free vibration and the sinusoidal forced vibration. From the maximum response curve with the parameter of the active stiffness ratio (�¡ =kc/k), the resonant state is detected in order to bound the maximum seismic response of this system. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
