Abstract

To apply smart structures to buildings, a new vibration control strategy is proposed for flexural-shear type frame structures with smart structures using piezoelectric actuators. Actuators are incorporated in columns, and the response of the entire structure is reduced by controlling the bending moment and axial force of columns. Combined application of these two control is performed by arrangement of actuators. Two control strategies were tested. One is model matching method and author is H(infinity) control theory. Excitation tests were conducted with a 4-story fame structure of total weight 2,000 kg and height 3.7 m having H-steels incorporating actuators as columns. Effectiveness of combined use of bending moment control and axial force control of columns with smart structures was confirmed.
