Abstract(s)

Passive, active, semi-active and hybrid control of wind and seismic induced vibrations in civil structures has been widely studied and reported in the last decades. Due to the noticeable advantages over other control approaches, semi-active control constitutes a promising technology to civil engineering applications, in particular intelligent damping systems such as those based on MR dampers. Besides, fuzzy based control systems are particularly suitable for non-linear structures or uncertain systems such as civil structures. In this context, this paper presents a semi-active control approach for a SDOF structure equipped with a MR damper under earthquake excitation. A fuzzy model of the MR damper and a fuzzy control algorithm are proposed and numerically studied. The results show the effectiveness of the suggested semi-active control system in reducing the response of the SDOF structure.
