Abstract text:
In this paper a three-storey building coupled with passive or semi-active tuned mass damper for reduction in the response of the structure to harmonic and seismic excitations is presented. Uncertainties in dynamic characteristics of a structure as well as the frequency content and intensity of the excitation may cause a deterioration of the performance of the passive tuned mass damper (TMD). For these reason a semi-active tuned mass damper (STMD) with variable damping is studied. Semi-active clipping control strategy is performed in order to optimize the performance of the STMD. The models are analyzed from numerical simulations point of view, for harmonic and seismic excitations. The OBTAINED results indicate that the efficiency of a STMD is better than that of passive TMD and comparable with that of an active tuned mass damper (ATMD).
Key Words:
