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.
