This research aims to develop a seismic response control method for dual high-rise buildings arranged in parallel. The connected control mechanism is utilized, and semi-active control method using variable damper is applied. As a variable damper, magnetorheological (MR) damper with biased hybrid magnet is introduced. Semi-active controller is designed by two method: LQ-feedback controller based mapping design, and genetic algorithm (GA) feedback controller based mapping design. Obtained controllers are investigated through computer simulation and control experiments. The results demonstrated the capability of presented control system design.
