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