This paper addresses the next generation benchmark problem in structural control, which focuses on the control of a full-scale, seismically excited, 20-story building. In this preliminary study of the benchmark problem, a lumped mass model of the full structure is employed. Magnetorheological (MR) dampers are applied to reduce the structural responses of the next generation benchmark building. 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. Moreover, MR devices can be constructed which are capable of generating the forces required for civil engineering applications. Further, the potential of the MR damper for seismic response control has been demonstrated previous analytical and experimental investigations.
