Abstract(s)
Among the different strategies available to control engineering vibrations, the semi-active
contrai based on Magnetorheological (MR) dampers have become a promising technology to
be used in civil engineering stmctures. The ability of these devices to change the stmctural
behavior without the need of large power sources is a major advantage that can be used to
justify their potential application to this engineering branch. This paper reviews the basic
concept of MR fluids and provides an insight of MR dampers dynamic behavior and the
available numerical procedures to describe the damper response. In the first section an
overview of the basic properties of the MR fluids and the fluid behavior under different flow
regimes are presented. Then, a selection of numerical models to simulate MR dampers
behavior will be presented based on the available literature.
