A semiactive control design is developed in which magnetorheological (MR) dampers are applied to reduce the responses of an asymmetric test structure. The MR damper is chosen for this study because it has attractive characteristics for civil applications. Specifically, devices based on MR fluid technology are reliable, inexpensive, relatively insensitive to temperature fluctuations, and require minimal power. Control input determination is based on a clipped-optimal control algorithm which uses absolute acceleration feedback. The performance of this method is studied experimentally using a 2-story building model with an asymmetric stiffness distribution and compared to results of passive control cases where a constant voltage is applied to MR damper.
