This paper reports a feasibility study of a smart member installed into a building structure by way of a bracing mechanism to achieve a relatively high augementation of damping effect. A dynamic numerical analysis with respect to a tall building, approximately 100 meter high, is reported. The proper adjustment of the damping coefficient of the smart member gives a over all damping factor about 10〜20 % to the building structure, and reduction of the response, deformation and shesr forces are numerically certified. Based on the requirements obtained from the previous study, a scaled model device was designed and employed for the experiments. The developed device depends but relatively little on the environmental temperature, the amplitude of the load and the excitation frequency. The feasibility of the full scale device is also reported.
