Seismic Mitigation of Tall Buildings Using Magneto-Rheological Dampers

In this paper, semi-active response control of tall buildings equipped with magnetorheological dampers is studied. Clipped-optimal control algorithm based on linear quadratic regulator (LQR) is employed for semi-active controller design. Bouc-Wenphenomenological model is utilized to investigate the nonlinear behavior of the MRdampers. The performance of the resulting control system is compared to the ncontrolledstructure for a benchmark building through simulation, and the efficiency of using MRdampers is evaluated.
