Abstract :
This paper proposes two methods for controlling flexible tall buildings using intelligent structural control. The first method can be used to control the vibration of tall buildings brought about by strong winds and large earthquakes. By placing actuators between a pair of flexible buildings the vibrational force to which both buildings are subject can be offset by the vibrational force which each buildings produces. By pairing buildings together the countervailing force required to resist large vibrational disturbances can be achieved. The second method for controlling vibration employs a lumped mass model used to prevent spillover due to neglected higher order vibrational modes. Filtered LQ control theory is used in their design and the effectiveness of teach method is demonstrated experimentally
