Several problems about estimating the seismic information and choosing performance index of the control in the algorithm of active variable stiffness (AVS) control have been discussed.AVS efficiency and its influence factors,such as damping of the controlled structures,time delay and arrangement of variable stiffness devices in the structure,are investigated by numerical examples.The numerical results show that AVS control technique is an available control method applied for suppressing the structural vibration.The economic and practical aim for AVS control can be achieved if it is reasonably applied to the controlled structures.
