000013692 520__ $$2eng$$aAn innovative design for a semi-active tuned mass damper (SATMD) with variable stiffness has been proposed for structural vibration control. The stiffness of the device can be continuously varied within a certain range using the variations of moment of inertia of an area. This adaptive tuned mass damper (TMD) is capable of real-time retuning and operates effectively in broad band frequency excitations. Employing the numerical simulations, the responses of a SDOF model coupled with the SATMD subjected to a seismic record are obtained. Wavelet transform is used to detect the instantaneous frequency of the excitation. The control effectiveness of the proposed SATMD is evaluated by comparing the results with those of the system coupled with a TMD. It is found that, the vibration suppression by the proposed SATMD is significantly superior to that of a conventional passive TMD.
