Mid-story isolation systems have previously been studied for decrease of the earthquake induced responses of high-rise buildings. The systems have been successfully applied to several buildings in Korea and Japan. Structural designers usually have to ensure that both the peak story and isolator drifts are within permissible limits. However, these two objectives conflict with each other. To solve this problem, a smart mid-story isolation system can be used for tall buildings. The system is composed of rubber bearings and magnetorheological (MR) dampers. The system was employed for an existing structure to reduce both the isolator and story drift. The control efficiency of smart mid-story isolator was evaluated based on a passive system. An artificial seismic load was made for numerical analyses for both systems. A fuzzy soft-computing technique with a multi-objective optimization was adopted to make control algorithm for decrease of both the inter-story and isolator drift. A numerical analysis results presents that the proposed method can effectively decrease the seismic-induced inter-story and isolator drift in the example of a tall building.
