AN EXPERIMENTAL STUDY ON SEISMIC RESPONSE CONTROL OF ASYMMETRIC BUILDINGS USING MR DAMPERS
|
´˜^i‰pjF |
This paper proposes a semiactive control system to reduce the torsional lateral coupling response in asymmetric buildings under lateral seismic excitations. Magnetorheological (MR) dampers are applied as semiactive control devices and the 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 the MR damper.
