A smart structure was tested for active vibration control of frame structures, in which bending moment of the columns was controlled by stack-type piezoelectric actuators integrated into the columns. Excitation tests were carried out for a model of a four-story building 3.7 m in height and 2000 kg in total weight in which 32 piezoelectric actuators 25 mm×25 mm×36 mm^H were used for the bending moment control. The actuators were installed in two ways: in one case eight actuators were attached to each column of the first story, and in the other case four actuators were attached to each column of the first and second stories. Two control strategies, a model-matching method and the H^∞ control theory were examined for the smart structure. The tests showed that the smart structure could effectively reduce the responses of the building model, and all combinations of actuator installation method and the control strategy had almost the same performance.
