To apply smart structures to buildings, a new vibration control strategy is proposed for flexural-shear-type frame structures with smart structure using piezoelectric actuators. Actuators are incorporated in columns, and the response of the entire structure is reduced by control of the bending moment and axial force of the columns. These two controls are applied in combination by appropriate arrangement of actuators. Two control strategies were tested. One is model matching method and the other is H^∞ control theory. Excitation tests were conducted with a 4-story frame structure with a total weight of 2000 kg and a height of 3.7 m having H-section steel beams incorporating actuators as columns. The effectiveness of combined use of bending moment control and axial force control of columns with smart structures was confirmed.
